Oil for the rear axle gearbox of the VAZ 2107: selection, replacement

VAZ 2107 is a rear-wheel drive car. Its rear wheels are driven by a rear axle and a cardan drive.

The rear axle is a gearbox that converts the amount of torque. To reduce the friction of the gears rotating in the mechanism, special oil is poured into the rear axle gearbox, as well as into the gearbox (gearbox).

The volumes of lubricating fluid that are necessary for the normal functioning of the VAZ 2107 transmission are indicated in the vehicle operating instructions. If for some reason it is not available, the information can be easily found on the Internet.

In this article we will talk about how much oil is in the VAZ 2107 gearbox and gearbox, how to measure the level of transmission fluid and change it correctly.

Oil volume in the VAZ 2107 gearbox what kind of oil

Oil in the gearbox - all the mechanisms that rotate and rub against each other need oil, the same with the gearbox, inside it there are gears (They are metal) that rub against each other during operation and if they are not lubricated with anything, they will quickly come out (They will become scuffed or even deformed and the gearbox will have to be replaced), and when lubricated they will rotate and rub against each other with much less friction and therefore the wear of the parts will be reduced (They will not fail so quickly) , in addition, the gears in the gearbox will also work more quietly and thus it will not hum and vibrate too much as it will if you completely drain the oil and start the car.

How much to fill (volume)

You won’t believe it, but there are also owners who don’t even know that the rear axle of a car also needs regular lubrication, although not as often as the engine. Also, there are drivers who believe that if the oil does not expel or ooze, there is no need to change it at all. This is all wrong and it is also necessary to perform this procedure, as in the internal combustion engine and in the gearbox.

The lubricant volume should be 1.3 liters. To fill the required level, you need to wait until the oil flows from the filler hole; this will be considered the optimal volume.

Replacement

The oil is changed according to the same algorithm as the oil in the gearbox, after a mileage, so that the oil is hot and drains better:

- unscrew the filler plug

— place a container for used oil under the drain hole

- unscrew the drain plug

- after the oil has completely drained, tighten the drain plug

- pour oil into the filler hole until oil flows out of it

- tighten the filler plug

Which one to pour?

It is recommended to fill the VAZ 2107 rear axle gearbox with transmission oil with a viscosity grade of 75W90 or 80W90 with API specification GL-4/GL-5. For example, CASTROL Syntrans Transaxle 75W-90 API GL-4 or Lukoil 80W90 GL-5.

In terms of volume, 1.5 liters of liquid is sufficient for replacement. Change at intervals of 30-40,000 km or every 3 years, whichever comes first.

What and how much to fill

It is best to fill the gearbox with gear oil recommended by the manufacturer. Information is indicated in the technical documentation, and it is very important to focus on compliance with the API class.

Almost all modern automakers require the use of oils of at least GL-4 and GL-5 in their transmissions, gearboxes and transfer cases, which contain extreme pressure and other additives and are adapted to work in the most severe conditions.

If you don’t know what kind of oil and how much is poured into the gearbox of your car, look for it in the table. We have collected information on approvals for various vehicles from many available sources.

If the car has 2 or 3 axles, then the total amount of fluid is indicated.

Oil for gearbox, transfer case and axles of VAZ-2107

VAZ-2107 is a rear-wheel drive small class sedan, produced from 1982 to 2012. During the years of the USSR, this car was considered the successor to the outdated family of VAZ-2101, 2102 and 2103 models, on the basis of which it was built. In addition to the 2107 sedan, the updated line consisted of the 2104 station wagon and the 2105 sedan, which, in comparison with the “top” 2107, had a basic level of equipment. In other words, 2107 is a modified version of 2105. The sedan competed with Moskvich and IZH cars. In post-Soviet Russia, the VAZ-2107 headed the “classic” family of VAZ cars, which was replaced by the Lada Granta in 2012.

Physical and mechanical properties

The oil belongs to the category of highly purified materials with a low content of sulfur additives. Technical characteristics depend on its physical and chemical properties, which in general look like this:

1. The operating temperature of TAD 17 is in the range from -20°C to +135°C.
2. Lubrication resource is about 80 thousand km. before replacement.
3. Kinematic viscosity at 100°C is in the range of 14-25.
4. The viscosity index is above 100 , which meets the requirements of GOST.
5. Density is 907 g/l.
6. The pH of the oil is neutral .

We can say that all characteristics comply with GOST for this type of lubricants.

When to change the oil in the gearbox and axles of a VAZ 2107

The recommended oil change interval for the gearbox and axles of the VAZ-2107 is from 30 to 40 thousand km, depending on operating conditions. Thus, an early oil change may be required in difficult climatic and road conditions, frequent off-road trips or in traffic jams, which often cause sudden starts and braking, which leads to overheating of the transmission. In such conditions, it is necessary to check the condition of the oil as often as possible, which in a spoiled state has the following signs: cloudiness, blackening, insufficient level, specific odor or thick consistency.

When replacement may be needed

The lubricant loses its properties over time. The oil in the bridge must be changed regularly, according to the instructions. But during operation, signs of malfunctions may appear, which indicate the need for a faster change of waste fluid:

• whistling and noise appear from the side of the bridge;
• when the nature of the load changes, knocking noises become audible;
• There are drips and traces of oil fluid on the gearbox.

The car care instructions state that in the VAZ-2107 the rear axle oil is changed for the first time after running in (2000 km). And then it needs to be changed every 60 thousand kilometers. But, given the difficult climatic conditions with ultra-low temperatures, bad roads and constant driving in city traffic jams, it is recommended to fill in new oil after 30 - 35 thousand kilometers. Unscheduled maintenance when purchasing a used car, major repairs are also accompanied by the replacement of lubricant.

Experts advise changing the lubricant in different seasons (winter and summer). In winter, the oil composition should be more liquid, with a lower pour point. And in summer it is more viscous.

How much oil to pour into the gearbox and axle

First generation 2107, 1982-2012

Compared to its predecessor 2105, model 2107 was distinguished by its original design of the radiator grille and rear lights. New front seats and an improved instrument panel with tachometer were also installed. The quality of the interior trim has improved slightly, resulting in more comfort. At various times, the VAZ-2107 engine range consisted of gasoline carburetor engines with a volume of 1.3 and 1.5 liters, as well as a more modern injection engine with a volume of 1.5 liters. For some time, a version with a rotary piston engine was offered. In 2008, a modification appeared with a 73-horsepower 1.6-liter engine equipped with distributed injection. The production of the “Seven” was carried out at the IZH plant until 2012. The total production volume of VAZ-2107 was 3.1 million units, including Egyptian-assembled cars (until 2013).

Oil groups

To choose which oil is in the VAZ gearbox 2107

to fill, you need to know the groups of these lubricating compounds:

What kind of oil to pour into the box of a VAZ 2110.

1. GL-4. 2107
   gearbox oil of this group contains many additives. Basically, such lubricants are used for cars with stepped gearboxes operating at high speeds with low torques, as well as those operating at low speeds with high torque.
2. GL-5. This oil for the VAZ 2107 gearbox is intended for so-called hypoid gears (gears rotate at an angle). In these models of domestic cars, the hypoid gear is located inside the gearbox, so
   only GL-5 grease
   can be
   poured the gearbox Such oil is also sometimes poured into the transmission, but only under severe operating conditions.

What oil to use for gearboxes and axles

Original

Transmission oil on a mineral or semi-synthetic basis is poured into the rear axle gearbox of a VAZ-2107 car. For cars of recent years of production, semi-synthetic is recommended. As for viscosity, SAE 70W, 80W or 85W is suitable for winter use, and SAE 90, 140 or 250 is used mainly in summer. In Russian operating conditions, the most popular is multi-grade oil with SAE 75W-80, 80W-85, 80W-90 or 75W-90.

Unoriginal

Before purchasing a suitable oil for the rear axle gearbox of a VAZ-2107, you need to pay attention to several important factors. Firstly, this is the choice of a manufacturer with a good reputation: Mannol, Total, Eneos, ZIC, Castrol, Kixx, etc. Secondly, regarding the type of viscosity: synthetic oil is more fluid, suitable for cars of recent years of production. Accordingly, mineral water or semi-synthetics are recommended for older cars. It has a relatively thick consistency, which means there is less chance of leaks in the presence of microcracks or gaps between contact pairs. Thirdly, when choosing an oil, they also pay attention to the current tolerance indicators API-GL-3, 4 or 5. The higher the indicator, the more oil additives. In the case of a VAZ-2107 with high mileage, you can limit yourself to API-GL-4 approval, and owners of cars from recent years of production can use GL-5. Below are suitable oils for the transfer case, axles and gearbox of the VAZ-2107 sedan.

• Castrol Syntrans Transaxle 75W-90 API-GL-4
• Lukoil Transmission TM-5 GL-5 75W-90.

Flushing the gearbox

When switching to another transmission oil, after purchasing a used car, or when undergoing scheduled repairs, it is recommended to flush the steering gear.

To do this, mix transmission or motor oil with diesel fuel in a 3:1 ratio.

The mixture is poured into the system after removing the old oil, then jack up one wheel, start the engine and leave it running at first speed for a few minutes. After this, the washing is drained.

How much liquid and what oils are filled in LADA (VAZ-2107)

Lada VAZ 2107 is a domestic car with a long history. Despite the great competition, it does not give up its position and occupies a leading position in sales in the secondary market. Today, almost two million Russians own a S7.

The car is presented in a sedan body. Rear-wheel drive. The gearbox is mechanical. There are ten modifications. Their main differences are in power plants and restyling.

Purpose

The oil is recommended for use in manual transmissions, axles and transfer mechanisms for domestic , but can also be used in other areas of mechanics:

• for agricultural machinery;
• for attachments;
• for stationary installations with rotating gear mechanisms.
• for long-term preservation of equipment.

is not used for automatic transmissions .

TAD 17 is used for the following purposes:

• protection of metal surfaces from corrosion;
• reducing friction and wear;
• preventing jamming in mechanisms;
• from the formation of pitting (cavities) on gears;
• heat removal;
• reducing the noise of machinery.

How much and what to fill in VAZ 2107

Fuel tank volume – 39 l. The manufacturer recommended using gasoline with an octane rating of 92 or 95.

The quality of operation of components and assemblies depends on the regularity of replacing lubricants. Engine oil lasts no more than 10 thousand km. After which it is necessary to change it to a new one. Lubricant fluid (with API quality level: SG, SH, SJ) is suitable for the VAZ 2107. During the procedure, a new oil filter must be installed. The same oil is used for the engine crankcase as for the power plant.

The service life of antifreeze is 60 thousand km. Even if the car is not used, the fluid loses its properties after two years, so it needs to be replaced.

The transmission oil is changed every 60 thousand km. At the same time, its level is periodically monitored. After 20 thousand km it may decrease, which will negatively affect the operation of the unit. The defect must be eliminated and oil must be added to the edge of the filler hole. This also applies to the rear axle housing. The gearbox filling volume is 1.6 liters.

Brake fluid should be replaced once every two years regardless of the vehicle's mileage. Domestic DOT-4 or a foreign equivalent is recommended.

Oil seals VAZ 2107 (dimensions)

You can order a crankshaft oil seal and other parts of the VAZ 2107, find out the exact price and other useful information in our office or by phone.

When is replacement needed?

The rubber reinforced cuff cannot be restored or repaired. Therefore, it is necessary to replace the crankshaft oil seal or other part on a VAZ 2107 as soon as the seal begins to leak or “take” working fluid.

Most often, replacing the axle shaft seal, gearbox, and gearbox on a VAZ 2107 is necessary under the following circumstances:

• wear due to long use;
• various damages;
• deformation;
• purchasing and installing an oil seal of the wrong size;
• low quality of the product;
• non-compliance of the product with AvtoVAZ requirements.

Required oil level in the VAZ 2107 engine crankcase

Absolutely all engines that were installed on the “classic” until recently have the same filling tanks. So, for example, the engine oil should be 3.75 liters. It is not always possible to mark this level yourself, since not every canister has a transparent scale. Therefore, you also need to navigate using the dipstick. Each dipstick has special MIN and MAX marks, which indicate the minimum and maximum permissible oil level in the internal combustion engine. It is necessary to fill until the level is between these two marks, approximately in the middle.

Roughly speaking, when changing the oil in a VAZ 2107 engine, you will need a canister with a volume of 4 liters, since it will be drained almost completely. In many service stations, when refueling, auto mechanics fill the entire canister, since 250 grams do not play a special role, provided that they are more than the recommended value.

Choosing oil for VAZ

What kind of oil should I fill in when changing the oil in the axle on a VAZ 2107, for example? It happens that the opinions of experts differ, but there are also common points. You shouldn't pour expensive oil - it's a waste of money. The choice of transmission oil is a personal matter. It all depends on the preference of the owner and the price of the oil. Mannol oil is often poured into the rear axle and it has proven itself quite well. XADO, of course, is of better quality, but still more expensive.

As for the brand of gear oil, the most common is 75W-90.

When to change the oil in the gearbox and axles of a VAZ 2107

The recommended oil change interval for the gearbox and axles of the VAZ-2107 is from 30 to 40 thousand km, depending on operating conditions. Thus, an early oil change may be required in difficult climatic and road conditions, frequent off-road trips or in traffic jams, which often cause sudden starts and braking, which leads to overheating of the transmission. In such conditions, it is necessary to check the condition of the oil as often as possible, which in a spoiled state has the following signs: cloudiness, blackening, insufficient level, specific odor or thick consistency.

When to change

The replacement frequency is on average 50 thousand kilometers for cars with a manual transmission, and 30 thousand for an automatic one.

It is more often necessary to change the oil on cars that are used in difficult conditions, which include:

• Off-road driving;
• Constant maximum vehicle load;
• Frequent towing of cars or trailers.

In a new car, it is recommended to replace it after the first 2-3 thousand mileage. The fact is that at the initial stage of work, new components undergo the so-called “grinding in”, which is characterized by increased formation of wear products.

Many car owners change the oil in the gearbox at the same time as the manual transmission, since both units use transmission fluid.

Be sure to check the level and condition of the oil in the gearboxes after purchasing a car on the secondary market. Usually, before selling, owners change lubricants only in places where they can be easily checked. Gearboxes are not one of these.

TAD 17 and TAD 17I

Relatively recently, a type of oil appeared, which is labeled TAD 17I.

The difference between these two lubricants does not concern their basic properties and we can only talk about the filling of components . “I” marking indicates that imported components were used in production. Basically, additives have been replaced, which are responsible for characteristics such as wear resistance and foam formation. To be precise, it was replaced, for example, by molybdenum disulfide with a more stable additive for elevated temperatures Molyslip XR250R .

If you compare these two oils in operation, there is no . Both varieties have differences, perhaps in price.

Signs of gearbox problems

The rear gearbox is one of the reliable mechanisms of classic Zhiguli cars and breakdowns rarely occur with it. However, like any other unit, it may have its own malfunctions, which are determined by characteristic symptoms. They are worth dwelling on in more detail.

Noise when accelerating

If during acceleration there is an extraneous sound from the gearbox installation site, then it can be caused by:

• worn out or incorrectly adjusted differential bearings. It will require dismantling, disassembling and diagnosing parts with subsequent adjustment;
• Incorrect meshing of the teeth of the main pair gears. Eliminated by proper adjustment;
• lack of lubrication in the gearbox. The lack of oil in the crankcase is restored, after which it is checked for leaks at the places where the sealing elements are installed.

If noise occurs both during acceleration and during braking by the power unit, there may not be many reasons:

• deterioration or failure of the bevel gear bearings of the main pair. Eliminated by replacing failed elements;
• Incorrect adjustment of the gap between the tip and the planetary gear. The mechanism needs to be diagnosed and replaced with damaged parts, as well as setting the required gap between the gear teeth.

When and how the gearbox howls if it is incorrectly adjusted

The nature of the sound can be different - it depends on the degree of misalignment; it does not matter whether the front gearbox is humming or the rear . Such a hum usually occurs both during acceleration and when coasting, but with the speed turned on. In neutral there is no sound. This is a very rare occurrence, since the gearbox is adjusted only once - when installing the main pair. If initially this transmission unit worked silently, and then began to make extraneous noise, it is not a matter of adjustment. Many car enthusiasts and “garage craftsmen” make the mistake of thinking that the gearbox is howling or humming because of a misaligned adjustment.

If the main pair is incorrectly adjusted immediately after installation, the gearbox will hum from the very beginning. If this malfunction is not eliminated immediately, the main pair will wear out and wear will appear on it, which cannot be compensated for in the future.

If you drive correctly and take care of your car on time, the question of why the gearbox is humming will not bother you even with a mileage of more than one hundred thousand kilometers. Take care of your steel horses and follow the traffic rules.

Frequency of fluid replacement in the gearbox and rear axle gearbox

It is recommended to change the transmission oil in the gearbox and rear axle gearbox of the VAZ 2107 every 35,000 km or after 3 years of vehicle operation.

The need for early replacement is indicated by whistling and noise from the side of the bridge, knocking noises when the nature of the load changes, and traces of oil fluid on the gearbox and gearbox.

It would not be superfluous to regularly (every 10 thousand kilometers) check the transmission fluid level. To do this, the car is installed on an inspection hole, overpass or lift. The filler plug is cleaned of dirt and unscrewed. The oil level is controlled, for example, with a screwdriver: the liquid should reach the edge of the hole.

If there is insufficient oil, it is topped up using a syringe or other device.

Along with measuring the liquid level, you can also check its condition. You need to unscrew the drain plug and drain some oil into a clean container.

The lubricant must be replaced if:

• It contains silvery metal dust or (much worse) grains of metal
• The color of the liquid is black or coffee (this may indicate the destruction of additives or water entering the oil)

Oil change instructions

You can change the oil in the gearbox and rear axle gearbox of a VAZ 2107 on your own. This is usually done simultaneously and immediately after the trip (at least 5 km so that the oil warms up).

You can buy 3 liters of oil at once - 1.3 liters for the gearbox and 1.4 liters for the gearbox. The residue can be used to lubricate locks, hinges and other interior elements.

In addition to oil, you will need:

• Wire brush
• Socket wrench "17"
• Hexagon on "12"
• Container for draining old fluid (at least 3 liters)

It is better to change the oil in an inspection pit or overpass. To simplify the procedure, it is advisable to have an oil blower or lever grease gun on hand. As an alternative, you can use a large plastic syringe with an elastic tube tightly wrapped around its end.

Changing the gearbox oil

Clean the drain and fill plugs on the transmission with a wire brush. Unscrew the drain with a hexagon to “12” and drain the oil into a previously prepared container. After this, remove the filler plug with a key set to “17”. Let the liquid drain completely. To speed up this process, you can raise the right side of the car using a jack.

As soon as the draining is complete, do not rush to tighten the plug - assess the condition of the waste liquid.

If there are chips in it, it is better to wash the gearbox housing. To do this, you can use special fluids, spindle oil or a mixture of transmission and diesel fuel (about 30% diesel fuel). Flushing occurs with the engine running and first gear engaged. After 3-4 minutes, the dirty liquid is drained and the drain plug is replaced.

To add fresh oil, take an oil pump or syringe with a tube, pump the lubricant through the filler hole to its bottom edge (until it starts to flow out) and tighten the plug.

Filling the gearbox with oil is sometimes carried out using a rubber hose and funnel. One end of the hose is lowered into the gearbox housing, and the other is led out into the engine compartment. A filler funnel is also inserted into it. The only disadvantage of this method is the need to warm up the oil or change it only in the summer.

Why do you need to change the oil?

As you know, the engine is the heart of any car. And the heart cannot function without blood. In this case, the blood is motor oil, which lubricates moving parts and also cools various components in the engine.

Over time, such a lubricant loses its characteristics, becomes dirty and cannot effectively cool the engine, which leads to various serious breakdowns. To prevent such problems with the engine, the VAZ 2107 oil change should be carried out every 15 thousand kilometers. Moreover, if the car is used in the city, it is best to reduce the service interval to 10,000 miles.

Viscosity grades

To choose which gear oil

better for the VAZ 2107 you need to decide on the viscosity class:

1. SAE75W90. This class includes semi-synthetic or synthetic oils that are suitable for all-season use. The lubricant can be used within the range from 40 to 35 degrees Celsius. Such oils can be used in cars that are operated in the harsh conditions of our country.
2. SAE75W85. This viscosity class is also suitable for all-season use in a box, and the temperature for maintaining performance characteristics varies from 40 to 45 degrees.
3. SAE80W85. Oils of this viscosity boil at 35 degrees and freeze at 30 or more.

Analogues of TAD 17

Similar TAD 17 transmission fluids include such foreign oils as Gear Oil EP 80w-90 , Multi Gear SAE 90 EP Esso , Mobilube ND90 BP , Spirax ND90 Mobil . All these brands have the same characteristics as domestic oil, and even surpass it in some ways. But the whole question is the price. Foreign analogues are much more expensive.

In order to buy 85W-90 TM 8-15, or 75W90 on sale . This will be what you need.

TAD 17 and TAP 15

TAP 15 often has a “B” after the type of oil, which means all-season. Technical characteristics of TAP 15 :

• Density at t 25ºС = 930 kg per m3;
• Viscosity at t 100ºС about 16:
• Pour point -20ºС;
• Sulfur content: no more than 3.0%;

Comparing these two oils, we note that TAP 15 is more used for specialized equipment. It is used in such machines and mechanisms as:

• in boxes and other rotating mechanisms on trucks and tractors, construction, road and agricultural special equipment;
• on conveyors of various industries, for lubrication of bevel, worm and spiral gears in various units and devices;
• mechanisms and gears operating with heavy loads on parts;
• for lubrication of railway rolling stock - locomotives and cars.

That is, there are also specifics of application for various types of technical devices.
