How to remove a VAZ 2107 axle shaft, replacing the oil seal, size, drawing, instructions with photos and videos

Experienced owners of VAZ 2101-07 cars know that costly repairs or complete replacement of the engine can only be avoided if all mechanisms are carefully taken care of.
The VAZ 2101 oil seal is an inexpensive, but very important part. It is not only used to seal joints, but also prevents the leakage of working fluid. If you install a low-quality reinforced cuff or do not change it in time, the element will leak. Often car owners do not notice this, so there is a risk of failure of the unit where this oil seal is installed.

It is always cheaper to buy a new seal on time than to repair or completely replace a specific unit later. Our company builds trusting relationships with clients. It is in our interests to provide the client with a suitable rubber product, which will be distinguished not only by its suitable size, but also by the high quality of the material.

Gearbox seal VAZ 2107 - description and purpose

An oil seal is a special seal in a vehicle that is necessary to seal gaps and cracks. For example, in a gearbox, the oil seal plays a vital role - it is fixed at the junction between the moving and stationary mechanisms, preventing oil from leaking out of the gearbox.

The oil seals in the VAZ 2107 gearbox are not made of rubber, as most drivers believe. In fact, this product is constantly in the transmission oil, and to keep production to a minimum, manufacturers make oil seals from CSP and NBR composite materials. At the same time, the gasket feels equally “good” at any temperature - from -45 to +130 degrees Celsius.

Box seal dimensions

The gearbox itself on the “seven” is designed for many years of service. However, the service life of the device directly depends on how often (and in a timely manner) the driver changes the seals. Indeed, during the operation of the machine, it is the oil seals and sealing joints that are the first to fail (tear, wear out, squeeze out). Therefore, timely replacement of the oil seal will help prevent expensive repairs of other gearbox mechanisms.

For proper replacement, you need to know the dimensions of the VAZ 2107 gearbox seals:

1. The input shaft seals have a weight of 0.020 kg and dimensions of 28.0x47.0x8.0 mm.
2. The secondary shaft seals weigh a little more - 0.028 kg and have the following dimensions - 55x55x10 mm.

Which ones are better

The main question for any VAZ 2107 driver when repairing the gearbox is: which oil seal is best to put on the shafts to avoid rapid wear? In fact, there is no universal option.

The standard equipment of the shafts involves the use of Vologda oil seals, but if necessary, you can install any others, even imported ones.

Industry leaders can be considered:

• OJSC "BalakovoRezinoTekhnika" (main materials of manufacture - composites and alloys);
• (the main manufacturing material is thermoplastic elastomers);
• (made from rubber compounds with various additives).

The most affordable oil seal for a box shaft costs 90 rubles; the more modern the manufacturing technology, the more expensive the product will be valued.

Oil seals

What is an oil seal?
This page showed oil seals by size for VAZ cars and catalog numbers, role and purpose... I welcome all readers to the RtiIvaz.ru blog. The page shows photographs of crankshaft oil seals as a set for the gearbox of a family of classic rear-wheel drive cars, as well as gearboxes of front-wheel drive eights and a dozen VAZs. The cuff of the rear gearbox, also called the rear axle, is installed in rear-wheel drive “Classic” cars.

In fact, there are many of them different in shape, size, and purpose. Some hold oil, antifreeze or antifreeze, others hold air, water pressure, all are designed to protect car parts from dirt, dust and other factors.

For example, the crankshaft seal and the camshaft keep oil from flowing between the joints of the camshaft journal and the seat of the engine block. The same role is played by the cuffs of the gearbox, gearbox, and axle shaft. The hub is protected from dirty water and dust from leaking antifreeze or antifreeze into the pump.

You can list the role of the purpose of car oil seals, I will only say one thing without them in our age of mechanical engineering. Someday they may disappear in a car, but this is already on the verge of fantasy when the car becomes something like a flying saucer “UFO”. In the meantime, we will think about these photo seals and where to use them.

Let's look at a photo of crankshaft cuffs for VAZ 2108 car engines; 2109; 2113; 2114; 2115; 2110; 2111; 2112; 2170; 1118 and 1111 "Oka".

The set includes three seals, two small and one large. Of the small ones, one goes to the front camshaft cover, the other small one goes to the front crankshaft of VAZ 2108 cars; 2109; 2113; 2114; 2115; 2112; 2115; 2170; 1118 and 1111 "Oka". The large rear one is located in the engine crankshaft on the clutch side.

• 2108-1005034 size: 28x42x7 2 pieces (front small ones numbered 2 and 3).
• 2108-1005160 size: 80x100x10 1 piece (large rear one under number 1).

That's all about the rubber cuffs (RTI) of the VAZ 2108 car engine.

Next photo is the crankshaft oil seals for Lada 2101-2107:

Let's look at a photo of crankshaft cuffs for VAZ 2101-2107 car engines.

Next is a photo of the rear axle gearbox oil seal for cars 2101-2107:

Signs of oil seal destruction

The seals are located directly on the shafts inside the box, so their wear can be visually determined only when disassembling the gearbox. However, any driver can quickly detect oil seal damage by eye, because there are obvious symptoms:

1. Transmission oil leaks under the car.
2. Constantly low oil level in the box.
3. Problems with shifting gears while driving.
4. Crunching and grinding in the gearbox when changing gears.

There are plenty of options. If there is an oil leak at the junction of the clutch bell and the engine, then it could be either the engine crankshaft rear oil seal or the gearbox input shaft oil seal. If there is a leak at the junction of the clutch bell and the gearbox body, the gasket is kaput. If it is wet at the rear end of the box - the gasket or oil seal of the secondary shaft

It would seem how the performance of such a complex unit as a gearbox can depend on a small part. However, loss of tightness for the box is fraught with big problems, because even minor losses of transmission oil will immediately affect the lubrication of moving elements.

It is recommended to change the oil seals in the VAZ 2107 box every 60 - 80 thousand kilometers. The replacement is associated with an oil change, so it will be convenient for the driver to perform these works at the same time. Before this period, it is necessary to change the oil seal only when there are clear signs of its destruction.

How to understand that it's time to change

The dense crankshaft rings are encased in a hard shell and consist of two parts - the front and rear oil seals. They prevent dust and dirt particles from entering the car crankcase and causing oil leakage.

Typically, the mileage of a part is designed to last one hundred and fifty thousand kilometers, but they can wear out earlier due to poor quality of the part or if the VAZ operates under high loads. The same can happen if there is constant overheating or if you do not change the oil and filter in a timely manner.

You can tell that a problem has arisen by the appearance of oily smudges on the gearbox or engine. It is worth considering that such problems with oil are fraught with rupture of the timing belt, which, as a rule, will lead to the risk of damage to the valves. This, in turn, already threatens serious repairs to the car’s engine, and therefore you cannot let the situation go on the brakes without doing anything to eliminate leaks.

Input shaft oil seal

The input shaft oil seal is located directly on part of the input shaft and is in contact with the clutch housing. Therefore, to replace this product, you will need to remove the casing.

To work you will need to prepare:

• nut heads;
• hammer;
• puller;
• flat screwdriver;
• knife (they are most convenient for removing the old gasket);
• new oil seal;
• transmission oil;
• new input shaft seal.

The procedure for replacing the seal can be carried out either on the removed box or directly on the car. However, it is easier and faster to change the product on a dismantled gearbox:

1. Disconnect the gear shift fork from the box.
2. Remove the release bearing by clamping it with a puller.
3. Unscrew the six nuts securing the clutch housing.
4. Remove the casing from the box.
5. Use the tip of a knife or screwdriver to pry up the old oil seal on the input shaft and remove it.
6. It is good to clean the landing area so that there are no traces of the seal, spraying or oil leaks.
7. Install a new oil seal, having previously lubricated it with transmission oil.
8. Next, assemble the box in reverse order.

Replacing the rear crankshaft oil seal

A sign that the rear crankshaft oil seal needs to be replaced is oil leaking through its lip.

In this case, the oil splashes around the rotating flywheel inside the clutch housing and then flows out through the cracks between the crankcase and its front cover.

If there is a strong leak, the clutch driven disc linings may become oily.

We carry out the work on a lift or inspection ditch.

Replacing the front crankshaft seal on a VAZ 2110, VAZ 2111, VAZ 2112

Welcome!

Crankshaft oil seal. thanks to it, the oil does not spill over the edge of the crankshaft, there are two entire oil seals on the shaft, for the scientific one, the front oil seal, the rear oil seal, the forward one can still be changed the most, but the rear one will be a problem, for this, in order to remove the gear, this will be needed, then a flywheel, not all people will take it for this.

The note!

The front seal is not removed in time quickly, during operation, the two crankshaft pulleys, the alternator belt, the fender cover, the wheel, etc. must be removed, but you need tools for this, namely: all these you need to remove and install the timing belt mechanism (see "Replacing the Timing Belt in Tens"), as well as two flathead screwdrivers that you will need, a small hammer, head. this is the correct size for the stuffing box, press again, pliers and motor oil, exactly as currently filled, you need to drive the car!

Where is the front crankshaft seal located?

VAZ 2110 cars are equipped with sets of engines, starting with a carburetor engine taken from nine and ending with a 124 injection engine, with 16 valve heads, but the lower part, namely the piston group of cylinders, they all have the same and therefore the crankshaft seal on All engines are located in the same place, but it is only more difficult to remove the stuffing box on the 124 engine, because it is not so easy to drop the timing belt on them and install it back, and this will need to be done, the location of this stuffing box can be seen in more detail in the two photos a little lower, in the large photo we have indicated the crankshaft pulley (behind it there will be another pulley that needs to be removed, all of them will be needed) and in the small photo the seal itself is already visible and both pulleys are removed from the car.

When should I replace the front crankshaft seal?

Oil seals are only changed after they start to pour oil through them, you can tell this by looking at the car (if the summer is dry outside), or if the oil starts to leave quickly, then the oil seals should also be checked to see if the oil will squeeze out through the crankshaft oil seal or at the rear (not really) and then immediately check the crankcase ventilation system and if possible clean it or if the hoses are pinched in it and then correct this problem, since the crankcase ventilation greatly affects the oil crankshaft seals la and works best with it, and perhaps the problem will go away and the seals will not change (see article: "Cleaning the crankcase ventilation system on dozens").

The note!

Typically, when the oil seal is worn out and a little oil begins to flow through it, when the engine is running, the pulley sprays all the oil on the engine, and therefore the oil and timing belt lightly fall onto the engine itself, which is very bad, in the end it turns out that the belt is all in oil (because of this it can jump and the car will start to start), so if possible, look under the engine, remove the timer cover as often as possible, everything under it, and if it turns out that the oil seal is slightly torn and does not hold the gap in lubrication system, you will immediately see that there will be no problems with the car in the future, and you will be assured that it will not sit on the road for a long time!

Secondary shaft oil seal

This gasket is located on the secondary shaft and disconnects it from the box flange. In this regard, replacing the secondary shaft oil seal proceeds according to a different scheme and is very different from working on the primary shaft.

To replace you will need:

• spanners;
• screwdriver with a flat thin blade;
• puller;
• pliers;
• transmission oil.

The work progresses according to the following algorithm on the removed gearbox:

1. Firmly fix the box flange so that it does not move.
2. Turn the nut securing it with a wrench.
3. Using a screwdriver, carefully pry up the metal ring and pull it out from the secondary shaft.
4. Place the puller against the end of the shaft.
5. Press out the flange together with the fixing washer.
6. Use pliers to grab the old oil seal.
7. Clean the seating area and install a new oil seal.
8. Next, assemble the structure in reverse order.

Video: operating instructions

Thus, replacing oil seals on a VAZ 2107 gearbox does not present any serious difficulties. However, inexperienced drivers are advised to seek help from professionals to avoid problems with the car, since working with the gearbox requires knowledge and experience.

What is needed for repair

If you decide to repair it yourself, take care of the site where you plan to inspect the machine. This could be an overpass or an inspection ditch in which it will be convenient to make the replacement.

The set of tools for work should include screwdrivers, cuffs, new oil seals, a set of heads and keys. Be sure to use sealant when making repairs. Remember that parts and consumables must be purchased only from the manufacturer, in order to avoid purchasing low-quality products or counterfeiting original parts.

Replacing the secondary shaft oil seal of a VAZ 2107 gearbox

The need to replace the secondary shaft oil seal in the gearbox of a VAZ 2107 car arises when oil leakage is detected from the gearbox. The presence of oil drops on the gearbox housing is not allowed, but oil sweating is acceptable, which is not a sign of oil seal damage. To perform the work of replacing the oil seal in the gearbox, you will need a three-jaw puller and fixing glue.

Removing the gearbox seal of a VAZ 2107

1. We install the VAZ 2107 car on an inspection hole or overpass (see “Preparation of the VAZ 2107 car for maintenance and repair”). 2. On VAZ 2107 cars with an injection system, remove the heat shield (see “Drivetrain - removal and installation”). 3. Disconnect the driveshaft from the rear axle gearbox and unscrew the two bolts securing the intermediate support of the driveshaft to the cross member (see “Driveshaft - removal and installation”). 4. Disconnect the elastic coupling of the cardan drive from the flange on the secondary shaft of the gearbox (see “Drivetrain - disassembly and assembly”) and move the cardan drive back. 5. Using pliers, remove the thrust ring.

6. Secure the elastic coupling flange from turning by inserting bolt A into its hole. Using a 30 mm wrench, unscrew the flange fastening nut and move the centering ring B of the elastic coupling along the shaft.

7. After tightening the nut a few turns, use two slotted screwdrivers to pry up the centering ring and remove it from the secondary shaft of the gearbox.

8. Unscrew the nut.

9. Remove the bolt from the flange hole. 10. Place the screw of the three-jaw puller against the end of the secondary shaft and press the flange off the shaft.

11. Remove the flange along with the washer.

12. Using sliding pliers, remove the damaged oil seal from the gearbox.

Installing the VAZ 2107 gearbox oil seal

Attention
Before installing the oil seal, check the condition of the inner cylindrical surface of the flange in contact with the oil seal.
There may be signs of corrosion and wear that should be removed by polishing. Before installation, lubricate the surfaces of the new oil seal with a thin layer of grease. 1. Press in the oil seal with a mandrel of suitable diameter.

For clarity, we show the following operation on a gearbox removed from a VAZ 2107 car. 2. Use a hammer to press the flange onto the shaft. Having installed the washer, apply fixing glue to the threaded surface of the shaft (according to the instructions for use) and tighten the nut.

1. Place the car on a lift.
2. Disconnect the wire from the terminal.
3. Remove the flywheel.
4. Remove the rear shield of the clutch housing, which is directed towards the bushings.
5. Unscrew the bolts (8 pieces).
6. Remove the holder from the part.
7. Now you need to knock it out of the gearbox; to do this, use a screw and a hammer.
8. Now we take the new element and press it into the holder. Outer diameter - (99±0.5) mm.
9. The working edge should be on the inside, if anything, turn it over.
10. A gasket that is torn must be removed. It will stay in place thanks to the lubricant on the holder.
11. Lubricate the edge with engine oil.
12. Also lubricate the crankshaft flange with engine oil.
13. Place the working edge onto the flange.
14. Tighten the bolts.
15. Reinsert the crankcase and bushings.
16. Replace the flywheel and clutch.

The process of disassembling the gearbox
is ready, the replacement of the VAZ 2110 gearbox seal has been successfully completed.

Let your machine run for a long time and not leak. A good owner's car is always in excellent condition. So it all depends on you! Monitor and check, take it for diagnostics on time if necessary. And try not to spend a lot of money on service centers, but also don’t try to do everything yourself if you don’t understand this area!

The meaning of the primary and secondary shaft oil seals

The direct and main purpose of these small parts is to reliably seal the metal parts and connections of the gearbox housing and other parts of the vehicle system to prevent transmission oil from leaking. Oil seals are made of durable polyurethane alloy using special compounds, since they are constantly in an aggressive environment. Oil is constantly present inside the parts, which negatively affects the condition of the part over a long period of time. Externally, these parts can be damaged as a result of mechanical stress due to breakdown or under the influence of an aggressive natural environment. The average resource or lifespan of units largely depends on operating conditions.

The manufacturer does not provide a specific guarantee for these parts; accordingly, it does not limit their service life; planned replacement is not required at certain mileages. However, in most cases, under normal operating conditions, the service life of the parts is sufficient for runs of up to 200 thousand kilometers. When used in harsh natural conditions, reliability decreases accordingly, and with it the service life of up to 100 thousand kilometers.

These parts are located at the junction of the transmission with the clutch in the case of the primary shaft, and the secondary one is located directly inside at the junction of the flange and the gearbox housing. Sealing of pipes and hoses, as well as metal parts, is achieved by tightly connecting two parts directly to the seals, which is a circle with several layers of polyurethane material. It is precisely because of the unsatisfactory condition of these small parts that transmission fluid often leaks outside the box. Therefore, responsible owners, when the first signs of malfunction appear, replace the part with a new one. Due to their simple design and the absence of any moving parts, these units cannot be repaired; they are simply replaced with new ones. However, their failure can cause major consequences in the form of failure of the entire gearbox as a result of oil “starvation”. Therefore, preventing the condition of oil seals is one of the important procedures in the daily maintenance of the VAZ 2107.

Dimensions of oil seals in the VAZ 2107 gearbox

To correctly replace VAZ 2107 gearbox seals, precise geometric dimensions are required, as well as the weight of the product. Otherwise, when installing other parts, the operation of the entire gearbox may be impaired, which may also lead to breakdown. The manufacturer has established clear dimensions for the VAZ 2107 gearbox seals; these parts must fit under them, regardless of the company that will produce them for installation on this model. For the secondary one, the length is 55 mm, the circumference height is also 55 mm, and the width/thickness is 10 mm. The secondary seal weighs 28g, although weight may vary by supplier and is not particularly significant.

How to replace the front crankshaft seal on a VAZ 2110-VAZ 2112?

The note!

This article covers the process of replacing the oil seal on 16 valve engines only, if you have 8 10 valves, then in that case, go to the article entitled "Replacing a Crankshaft Seal on 9s" in it, with an example of an 8 cylinder engine, everything is described!

Conclusion:

To remove the oil seal, first remove the timing belt from all the upper pulleys and rollers (as explained in the article on replacing the timing belt on a car, we already mentioned the link to this article at the very beginning of the article, scroll up), then the alternator belt will be removed, you need to remove the crankshaft pulley (How to remove the belt, described in the article: “Replacing the alternator belt on a VAZ”), after completing the operations, proceed to removing the large and small crankshaft mechanism, both gears are fixed with one bolt (it holds them in the center ), which is there (see photo 1), but to get to it, the jack must lift the right side (when you look at the car, see), remove the wheel (see article: Correct replacement of wheels on cars) and, if necessary, remove the wheelbarrow , if the suspension does not interfere, then without removing it, turn the pulley bolt and first of all, remove the large pulley from the crankshaft, install a washer on it without losing it, remove it from the large crankshaft pulley (see picture). photo 2), follow the belt with a small release of the pulley (see photo 3), and at the end remove the small pulley from the shaft, that's all, you can assume that you have hit the packing, but there is one caveat, there is a wrench (see photo 4), when this is done, you can remove the oil pump cover seal using thin screwdrivers, when you remove it, notice that it is on the side, Install the new packing in the same way.

Any part of a modern car, no matter how high-quality and reliable it is, has its own working life, upon reaching which it must be replaced, which allows for the most comfortable and safe operation of the entire propulsion system. Crankshaft oil seals are no exception; they should be diagnosed and replaced approximately every three years. Today we will talk about how to replace the front crankshaft oil seal at home.

Diagnostics of VAZ 2107 gearbox seals

A responsible car enthusiast, owning a domestic rear-wheel drive car, is obliged to constantly monitor the condition of many units and components. One of these are oil seals. There are simple but quite labor-intensive means of checking and preventing these parts. To do this, you need to lift the car on a lift or drive it into a pit and conduct a visual inspection of the box body. In the places where the seals meet the parts of the clutch or rod there should be no fogging in the form of oil stains or drips of this substance. Fogging at the place where the part is attached is the first sign of failure; even if there are small spots, it is necessary to replace it, since the leak will only increase in the future.

It is also necessary to wipe and clean the parts from dirt and dust and inspect them for cracks, which may subsequently leak.

The simplest method of prevention without using a lift is to periodically check the oil level in the crankcase using a dipstick.

In addition, one of the signs of failure of parts and the subsequent need to replace the seal of the VAZ 2107 five-speed gearbox is a crunching sound when shifting gears both down and up. Also, this situation may be accompanied by a parasitic hum, which is not inherent in this type of box. At the first signs of malfunctions, it is necessary to urgently carry out a visual inspection, either yourself or go to a specialized service.

Replacing the front crankshaft oil seal on a VAZ 2110

What tool is useful for such repairs: a screwdriver, engine oil (for topping up), a pipe or a wrench head with a 41 mm outer diameter.

Some people also remove the oil pump when replacing the oil seal, but we will show you how to avoid this. Of course, if you remove the pump, you will avoid possible distortion of the seal, but you will spend an order of magnitude more time. So, first of all, remove the timing belt.

1. Now we remove the gear pulley. If you have a puller, perform this operation using it. If there is no puller, as often happens, then pry it off using 2 screwdrivers.

1. When the pulley is removed, we can examine the oil seal itself. Don't pay attention to its appearance, it may look almost like new. But at the same time, it may be dry, which is why oil oozes through it.

How to change the oil seal on a VAZ 2107 gearbox

The procedure for replacing the rear oil seal of a VAZ 2107 gearbox differs from that on the front part due to the design features of the fasteners, as well as the very location of the parts and their design. In general, both procedures are divided into several stages.

Replacing the input shaft oil seal in a VAZ 2107 gearbox

Replacing the front oil seal of a VAZ 2107 gearbox occurs in several stages:

1. First you need to disconnect the parts of the clutch with which this part interacts by dismantling the clutch fork, housing and release bearing, which are secured with several bolts.
2. Then it is necessary to dismantle the casing itself, thereby freeing up space for removing the oil seal itself.
3. After this, you should remove the used part by removing it from the seat using a knife. The vacated seat must be carefully processed to remove any remaining waste oil from the part, as well as other contamination.
4. A new unit is installed in its original location, lubricated with transmission oil, and the entire system is reassembled in the reverse order.

Replacing the secondary shaft oil seal in a VAZ 2107 gearbox

The secondary oil seal is changed in another way:

1. Fix and dismantle the gearbox flange, since it is this part that is fixed to the secondary oil seal.
2. After dismantling, it is necessary to press it out using a special puller and gain access to the oil seal itself.
3. Next, use a screwdriver or other tool to remove the used part, and also treat the landing site.
4. Install the new element and reassemble in reverse order.

Work order

1. First of all, we disconnect the negative terminal, as a result of which we de-energize the VAZ-2110. After this procedure, it is necessary to remove the protection of the timing belt and the car engine.
2. We loosen the tense timing belt, and then simply remove it, making sure that the marks match.
3. We remove the right wheel in front of the VAZ. After completing the manipulations with the wheel, the generator drive belt is also removed, after which you must unscrew the bolt securing the crankshaft pulley.
4. The engine oil is drained and the oil pump, to which the front oil seal is attached, is dismantled. We replace the cuff and carefully coat it with sealant.
5. The cuff on the inside is generously coated with oil, then remove the seal and take out the front cuff of the car. We collect all this in the reverse order of the above steps.

Replacing the rear cuff will be much more difficult. The procedure for carrying out repair actions is as follows:

1. We remove the negative terminal from the battery, after which it is necessary to remove the clutch basket. After these procedures, we proceed to dismantling the flywheel, and then to removing the crankcase casing.
2. The rear oil seal holder is removed by unscrewing the tightened bolts securing it. We unscrew the bolts that secure the flywheel.
3. While holding the latch, you need to pull out the seal. To do this, you can use a vice and inspect the fixing part of the cuff. If there are any defects in it, this part is also replaced, and then the working edge of the new cuff is placed inside the retainer and the gasket is replaced.
4. The edge of the crankshaft together with the flange is generously coated with oil. We install the holder, very carefully tucking the working edge of the sealing ring onto the flange. Reassembly after repair is carried out in the reverse order. After making repairs, you need to check from time to time to see if engine oil is leaking.

What to do if one day you notice that a small puddle of oil appears under the car. There are two main reasons for oil leakage from the engine: either the oil pan gasket is broken, or there is a problem with the rear or front oil seals.

If the problem is in the gasket, then it is very easy to install. You need to crawl under the car and look at the pan. If it is wet where it connects to the engine, then the problem is in the sump. If you still determine that the problem is in the oil seal, then see the instructions below. Of course, you can go to a service station, but it will be expensive. Therefore, I advise you to replace the VAZ 2110 crankshaft oil seal with your own hands.

Tips and recommendations for replacing the oil seal in a VAZ 2107 box

There are many manufacturers of spare parts for VAZ cars on the market. These are both domestic and foreign enterprises. A lot of these also produce seals. However, the negative side of diversity is the unstable quality of spare parts. There are frequent cases of defects, regardless of the country of origin. Therefore, responsible drivers should carefully examine the unit when purchasing it for quality of workmanship, the presence or absence of cracks.

In general, despite the low cost of the part itself, the installation process takes quite a lot of time, so the best option would be to purchase the part from the car manufacturer itself, which complies with the design dimensions, as well as the production technology of original spare parts.

Also, when installing new parts, it is always necessary to have a drain container on hand to remove excess parts of the transmission fluid, as well as new fluid for subsequent topping up.

The main reasons for device failure

The main factor indicating that crankshaft oil seals on VAZ 2110 models require increased attention is the numerous oil flows in the engine system, which arise under the influence of a number of reasons, including:

• Aging of the unit and its natural, physical wear;
• Problems with the installation of the device or its incorrect installation, which entails the occurrence of cracks on the working plane of the cuff;
• Various mechanical damages;
• Use of low-quality rubber.

Gearbox and automatic transmission repair

The transmission is one of the most reliable units with a long service life. Breakdowns are usually caused by irregular maintenance, improper operation, and the use of counterfeit consumables and components.

VAZ 2107 axle shaft broke, what is it for, design, characteristics, replacement

Home › Cars › VAZ ›

The rear axle is one of the main components of a car's transmission. Not only the driving performance of the car, but also the safety of the driver and passengers depends on the serviceability of its elements. In this article we will talk about the axle shafts of the rear axle of the VAZ 2107, consider the purpose of these parts, design, possible malfunctions and ways to eliminate them on your own.

In rear-wheel drive cars, which the “seven” actually belongs to, the rear wheels are driving. It is they, rotating, that make the car move.

The torque is transmitted to them from the gearbox through the drive (cardan) shaft, gearbox and axle shafts. There are only two axle shafts: one for each rear wheel.

Their role is to transmit torque from the corresponding gear of the gearbox to the wheel rim.

Axle shaft design

The axle shaft is an all-metal shaft made of steel. At one end there is a flange for attaching the wheel disk, and at the other there are splines for engagement with the gearbox gear. If we consider the axle shaft assembly, then in addition to the shaft, its design also includes:

• oil deflector;
• sealing gasket;
• oil seal (cuff);
• bearing.

Each of the axle shafts is installed in the corresponding (left or right) rear axle housing. An oil deflector with a gasket and an oil seal are used to prevent lubricant from leaking out of the casing. The bearing is designed to ensure uniform rotation of the axle shaft and distribute shock loads coming from the wheel to the rear axle of the vehicle.

Main technical characteristics of VAZ 2107 axle shafts and their elements

Axle shafts for the “seven” in Russia are produced under catalog number 21030–2403069–00. The right and left parts, unlike some other rear-wheel drive cars, are absolutely identical in the VAZ 2107. They have a diameter of 30 mm (for the bearing) and 22 slots. On sale you can also find so-called reinforced axle shafts with 24 splines, but to install them you will need to change the design of the gearbox.

Axle bearing

The bearing is the element that bears most of the loads. And although its declared resource is about 150 thousand kilometers, it can become unusable much earlier.

It all depends on the operating conditions of the car, the serviceability of other transmission parts, as well as the quality of its manufacture.

The most reliable today are considered to be bearings from the Vologda Bearing Plant, produced under article numbers 2101–2403080 and 180306. Imported analogues have catalog number 6306 2RS.

Stuffing box

The axle shaft cuff has a much shorter lifespan than the bearing, since its main working material is rubber. It needs to be changed every 50 thousand kilometers. Axle shaft seals are available under catalog numbers 2101–2401034.

Malfunctions of VAZ 2107 axle shafts, their causes and symptoms

The main failures of axle shafts include:

• shaft deformation;
• fracture;
• wear or cutting of splines;
• Damage to the wheel rim mounting threads.

Deformation

The axle shaft, although made of high-strength steel, can become deformed under high loads.

Such a malfunction is often a consequence of gearbox jamming, bearing problems, or the corresponding wheel falling into a deep pothole.

A sign of deformation of the axle shaft is strong vibration of the wheel rim, sometimes accompanied by a hum, knocking, or crackling noise.

Fracture

The result of a wheel hitting a pothole or a strong impact on a bump can be a fracture of the axle shaft. In this case, the car loses control because one of the drive wheels stops rotating. If the axle shaft is broken, the gears of the gearbox may also fail, so if such a malfunction occurs, it must be checked.

Worn or cut splines

Natural wear of the axle shaft splines may appear after 200–300 thousand kilometers. More often they are cut off, which occurs when one of the wheels jams and the gearbox malfunctions. Also, the splines are cut off due to wear of the axle gear teeth that mesh with them.

A sign of wear or cutting of the splines is a crunch (crack) from the axle shaft, which usually occurs when starting or moving downhill. The crunching sound indicates that the gear teeth are slipping between the axle shaft splines.

Damage to wheel threads

It is quite difficult to damage the threads on the flange, but such troubles still happen. The reason for this may be non-compliance with the tightening torque of the wheel bolts, incorrectly set direction of the bolts when tightening, or violation of the thread pitch on the bolts. A sign of thread damage is vertical play in the wheel, or beating in the rear of the car while driving.

Gearbox repair (automatic and manual transmission)

There are no unnecessary or unimportant components and assemblies in the car. However, the gearbox is treated differently. This mechanism must work clearly. And if you notice problems and malfunctions (the gearbox is noisy, oil leaks from it, it overheats, the gear switches off spontaneously, etc.), you should immediately contact an auto technician so that our employees can repair the gearbox as quickly as possible - and with this quality.

It doesn’t matter what type of gearbox you have: mechanical, hydraulic, CVT, robotic or dual clutch. We employ professionals whose specialization is repairing transmissions of any device and brand.

Here's what can happen to your car's gearbox:

• gears, bearings, synchronizers wear out;
• the oil will become contaminated and its level will decrease;
• backlashes will appear, causing unpleasant noises;
• oil seals and gaskets will become unusable, etc.

Alas, gearbox repair is inevitable. Every car enthusiast whose car has traveled tens of thousands of kilometers encounters it. Nothing lasts forever – and this applies to the checkpoint to the fullest. To avoid more serious breakdowns and even accidents, you should contact our auto repair center when you notice the first signs of a malfunction, or better yet, entrust us with diagnostics in advance and identify what exactly needs replacement or restoration work.

Replacing the rear axle shaft on a VAZ 2101 - 2107

If there is excessive play in the rear axle bearing or it is damaged, it will be necessary to dismantle it and, if necessary, even replace it.

This article will discuss the procedure for removing and installing the rear axle shaft on cars such as VAZ 2101 - 2107.

This repair is not particularly difficult and can be done without any problems with your own hands. But you will need a lot of tools, namely:

• Jack
• Balloon wrench
• 17 mm head
• Extension
• Driver and ratchet handle
• 12mm socket and small ratchet (for removing drums)
• Penetrating lubricant

First, I will give a detailed description of this procedure in my video clip, which was specially filmed for this article, and only then I will make a step-by-step guide in the form of photographs in case a problem suddenly arises with the video and for some reason it does not play.

Photo report on replacing the rear axle axle shaft on a VAZ “classic”

So, the first thing you need to do is remove the rear wheel of the car, after first lifting the car with a jack. After this, remove the rear brake drum. When we have completed this task, we get something like the following picture, which is shown in the photo below:

After this, we place the holes on the flange so that the axle mounting nuts are visible through them:

And using a wrench and a 17mm socket, unscrew these nuts through the holes:

When these two nuts have been unscrewed, you need to slightly turn the flange so that two more appear through the holes:

And unscrew them in the same way as the previous two. After this, you must try to remove the axle shaft from the rear axle housing of the VAZ 2101-2107. There is a simple, but at the same time quite proven method for this: you need to turn the wheel inside out and tighten it lightly with two bolts:

And with sharp jerks we knock the axle shaft off the splines:

After the axle has come off, you can unscrew the wheel and finally remove it by hand:

We replace the bearing or the axle shaft itself if necessary and install it in the reverse order. The price of a new part is from 1200 rubles per piece.

How to check and replace a VAZ-2107 axle shaft

Measuring the axial free play of the axle shaft on a car

The axial free play of the axle shaft can be measured on a vehicle both with the wheel and brake drum removed and without them removed. In the first case, the measurement is more accurate.

For what:

– remove the caps from the rear wheels and loosen the bolts securing them;

– place stops under the front wheels and lift the rear axle;

– release the parking brake and set the gear shift lever to neutral;

– remove the wheels and brake drums;

– screw device 02.7834.9504 to the axle shaft;

– pass the indicator leg extension 1 through one of the two large holes of the axle shaft until it stops in the brake shield or oil deflector and secure the indicator;

– take measurements with an indicator, applying a force of about 49 N (5 kgf) to the axle flange in both directions, along the axis of the rear axle. Free play should not exceed 0.7 mm. Measure the free play of the axle shaft without removing the wheel and brake drum as described above, taking into account the following features:

– secure device 02.7834.9504 using one of the holes for the wheel bolts;

– pass the leg of the indicator extension through another hole for the wheel mounting bolt;

– the force applied to the wheel along the axis of the rear axle should be about 98 N (10 kgf), the free play of the axle shaft should be up to 0.7 mm.

Replacing the axle shaft and its cuff

We hang the rear of the car on tripods, remove the rear wheel and brake drum. Using a jack, we lift the disassembled edge of the rear axle beam so that after removing the axle shaft, the oil does not spill out.
