Dismantling and assembling the gearbox of a VAZ-21213 car

Purpose and design of the gearbox

The variable gearbox can simultaneously perform several functions.
By controlling the gearbox, the driver rationally distributes the torque obtained when rotating the crankshaft. The shaft cannot be rigidly connected to the wheel drives, since it is necessary to ensure the ability not only to move, but also to stop the car, move it away, and also move in reverse. The gearbox allows you to separate the engine from the transmission for a long time. This has to be done when the car is parked for a long time or when it is coasting.

The gearbox ensures the conversion of torque, which is transmitted from the engine to the drive wheels. As a result of its operation, the wheels can rotate in a wider range of frequencies than the engine rotates.

Our experts answer the most frequently asked service questions.

Why is timely oil change necessary?

How often should you change your engine oil? The basic rule that car owners should follow is to change the oil every 10,000 km, or once a season (spring and autumn).

What improvements will occur as a result of gearbox tuning?

The factory gearbox has a number of disadvantages, for example: “long” gears, loss of torque when shifting. Gearbox tuning will help you customize your car to suit your wishes.

Is it worth replacing the gearbox with a repaired one?

Of course it is, with one important note. The gearbox must be repaired in a “trusted” place and have a warranty.

Disassembly and assembly of the VAZ 21213, 21214 Niva gearbox

After the box is removed from the car, you can begin disassembling it, which is performed to replace failed elements. To disassemble the gearbox on a VAZ 2121 and Niva 2131, prepare a standard set of tools and perform the following sequence of actions:

• Having removed the box, drain the oil from the crankcase, after which we disassemble the clutch release mechanism.

• From the toe of the secondary shaft, having unscrewed the fastening nut, press the flange of the elastic coupling.
• Next, use a twenty-two key to unscrew the reverse light switch from the box body.
• Remove the gear selector mechanism, and then disassemble it if necessary.

• Now we need to remove the gearbox housing cover. To do this, use a ten-point socket to unscrew the ten nuts securing the cover. Remove the nuts and washers located underneath them.
• Remove the cover and the sealing gasket located under it.

• Unscrew the inner nut securing the rear gearbox cover. To do this, move the fork rod of the first and second gears down, resting a screwdriver on the rod through the hole in the gear selection mechanism. When the rod moves, second gear will engage.
• And use a thirteen key to unscrew the nut securing the cover.
• Remove the cover and bearing of the fifth gear and reverse gears.

• Remove the rear bearing thrust ring from the secondary shaft.
• Now you can remove the outer ring of the bearing along with the cage and rollers.

• Now remove the inner ring, spacer sleeve and oil flinger from the shaft.

• To remove the shafts, they must be locked by engaging the appropriate gears. The second gear was engaged before removing the rear cover of the box, and to engage the fifth or reverse speed, use a ten key to unscrew the bolt securing the fork to the rod, then press the fork with a screwdriver and move it down, thereby engaging the reverse gear.

• Now that the shafts are locked, use a 17mm spanner to unscrew the bolt securing the fifth gear and reverse gear block, and then remove the bolt and gear block.
• Secure the block in a vice with pads made of soft material and press the inner bearing ring off it.

• Next, remove the fifth gear bushing, gear with synchronizer blocking ring, and hub from the shaft.

• Immediately remove the synchronizer coupling from the shaft.
• Then we turn the fifth gear and reverse fork towards the secondary shaft and remove the reverse gear intermediate gear.
• Remove the transmission clamps.

• Now that the gears and bushings have been removed, we remove the rod and its fork from their seat. Then remove the plug itself from the stem.

• The locking block must be removed from the hole in the box housing. To do this, use a magnetized screwdriver.
• Next, remove the reverse driven gear from the secondary shaft.

• Having removed the gear, we remove the locking key from the groove on the shaft and move it to the side so as not to lose it.
• Using a ten-point socket, unscrew the bolt securing the fork to the third and fourth gear rod.

• We take out the rod and remove the locking block from it.

• Next, using a magnetized screwdriver, remove another locking block located in the groove between the sockets of the first and second, as well as the third and fourth gears.
• We also use a socket to unscrew the bolt securing the fork to the rod of the first and second gears. And take out the rod.

• Now we need to remove the secondary shaft intermediate bearing retaining plate. To do this, use an impact screwdriver to unscrew the three screws that secure it. Remove the screws and the special lock washers located underneath them.

• Remove the locking plate.
• Using a 19mm spanner, unscrew the nut securing the reverse idler gear axle. At the same time, we keep the axis itself from turning with a twenty-four key.
• We take out the axle.
• Remove the clutch housing.

• Remove the spring washer from the input shaft.
• Now we need to remove the countershaft front bearing clamp washer. To do this, secure the input shaft in a vice through soft metal spacers and use a nineteen key to unscrew the bolt securing the clamping washer.

• Remove the bolt and washer.
• Now you can remove the bearing. To do this, use two flat screwdrivers to pry it up and remove it.

• After removing the bearing, its rear ring may remain on the shaft. If the ring remains, use two flat screwdrivers to press it off the shaft.

• Remove the rear ring and thrust ring.

• Now we need to remove the rear shaft bearing. To do this, insert a flat-head screwdriver between the end of the bearing and the first gear gear of the intermediate shaft, and move the bearing.
• And we take out the outer ring with the separator and rollers and its inner ring.

• We move the intermediate shaft a little back and remove it from the gearbox housing.

• Remove the input shaft. Using two flat-head screwdrivers, hook it on its rear bearing and pull it slightly towards you, and pull it out of the box body.
• If necessary, disassemble the input shaft.

• Now remove the needle bearing from the front end of the secondary shaft.
• Next, remove the shift forks for 1st and 2nd gears, as well as 3rd and 4th gears.

• Remove the secondary shaft intermediate bearing. To do this, use two flat screwdrivers to pry it by the mounting ring.

• Tilting it slightly to the side, we pull the secondary shaft out of the box body. If necessary, disassemble it.

At this point, the repair work on disassembling the gearbox on the VAZ 2121 and Niva 2131 has been completed. Make the necessary repairs, then reassemble in reverse order.

Is your Niva's transmission starting to fail? The situation is not pleasant: it becomes uncomfortable to drive, and safety on the road remains in great doubt. We will talk about the reasons for the failure of transmission elements another time. Now let’s try to figure out what to do in fact: change the box or repair it.

The Niva car is positioned as an SUV that has increased cross-country ability. Due to this, there is a demand for the car. A durable load-bearing body has been installed. The Niva 2131 model is built on the basis of the LADA 4×4. Its tuning allows you to change the exterior and performance characteristics for the better. Since the mid-1990s. Injection engines have become available for Niva cars.

In addition to passenger cars, self-propelled vehicles are also produced under the Niva brand. In particular, this is Niva SK 5. This vehicle is a combine harvester designed for harvesting crops. The machine runs on diesel fuel.

Assembly

Assembly of the fifth gear, reverse gear and gear selection mechanism is carried out in the reverse order of disassembly, taking into account the following:

ALER: I recommend looking at the comments made by firesanek

(Remaking the gearbox into a “torn package”).

During the assembly process, you need to remember one important operation - turning the shafts after each next installed part. The shafts should rotate easily, without jamming. If you feel tight rotation after installing any part, then this part is defective and must be replaced. Don’t be too lazy to do this, otherwise the work will be in vain, the gearbox will either not work properly or will quickly fail again.

Clamp the secondary shaft in a vice through a rag and use a grinder to make cuts on both sides at its rear end to secure the shank nut:

Attention! If the output shaft is worn or faulty, it makes sense to make cuts on the replacement shaft purchased only at the very end of the assembly process, after installing the gear shift mechanism and checking its operation. If there is a defect due to these cuts, you will not be able to return the purchased shaft to the store.

Lubricate the inner race of the input shaft bearing with oil or lithol. We place the input shaft on a wooden block, put the bearing on it with the groove with the locking washer facing up. Through a mandrel (pipe of suitable diameter) we place it on the shaft:

We install the spring ring and the locking ring, press it with light blows of a hammer through a chisel until it is completely fixed:

Diagnostics and repair of the speed box

To carry out a full diagnosis, the speed box must be removed. As a rule, there is a need for this if vibrations, extraneous noise, or oil leakage increase during movement.

How to remove the box? Before you begin removing the gearbox, you must remove the transfer case. Without an inspection hole, it will be difficult to carry out repair work, for example, unscrewing the cardan shafts from the transfer case. The stabilizer can also be removed. The housing of the air filter element must be removed.

In order to remove the gearbox, you should disconnect the lever rod, the clutch housing cover fastenings, the driveshaft, bolts, nuts, and remove the bracket. The suspension of the power unit is adjacent to the body. To remove it you need to unscrew the fastening nuts.

To extend the service life of the VAZ 21213 gearbox, it is advisable to periodically check the level of transmission fluid and change it in a timely manner.

Mineral oil can be added to the machine. However, semi-synthetic and synthetic options have better performance. The advantage of the latest types of oils is that even in winter the gears will be easily engaged.

Timely maintenance of the Niva gearbox allows you to avoid a complete overhaul of the gearbox. Assembling all the dismantled parts is a painstaking task, so it should be trusted to professionals. Replacing the gearbox input shaft bearing is a common procedure that is ordered at a service center.

The gearbox linkage is an element of a multi-lever assembly, which is designed to connect the gearbox lever and the rod that fits the power unit. In Niva Chevrolet cars, the rocker is located under the bottom of the vehicle, next to the cardan. This component is susceptible to contamination and the formation of moisture on it, which over time can deteriorate the quality of lubrication of rubbing parts. As a result, parts begin to wear out, which can subsequently lead to various problems.

What kind of rocker should I put on a Niva Chevrolet? This question came to the mind of every Niva car owner who had to deal with a malfunction of this element. In fact, there is nothing difficult in choosing a component.

In practice, many car owners of the above car models install mechanisms from classic Fiat cars on their vehicles. According to reviews on the Internet, these devices are completely suitable for installation in a Chevrolet Niva. However, there is also a negative side. In practice, Niva cars equipped with a mechanism from Fiat cars require more careful adjustment of the element. In addition, despite Italian quality, these components of the transmission system are more susceptible to wear and tear.

Therefore, when choosing a mechanism, you should not “be fooled” by the stories of handicraft “garage” craftsmen and come up with a new headache for yourself. For installation in a Chevrolet Niva, it is better to purchase a standard rocker, which is equipped with basic models of Niva cars.

Chevrolet Niva gearbox

The design of the gearbox on a Chevrolet Niva is not original and was developed much earlier than the launch of the conveyor. The type of gearbox is a mechanical five-speed with a three-shaft structure. It is possible to highlight the key components of the box, since the complete diagram of its structure is quite voluminous.

Primary shaft (1). It transmits force from the rotating motor. Can be decoupled from the engine for a short time using the clutch release.

Box housing (3). All mechanisms are lubricated with transmission lubricant, so they are located in a sealed crankcase where this lubricant is poured.

Primary shaft oil seal (4) and secondary shaft oil seal (5). It prevents lubricant from leaking where the shaft enters the crankcase.

Gear synchronizers (7, 8, 9). They serve to more clearly engage gears and fix the selected gearing.

The intermediate shaft (6) is designed so that it is in constant engagement with the input shaft. The intermediate shaft houses the gears.

Secondary shaft (2). Is a driven shaft. It also has gears that can move along the axis of the shaft.

The gear selector is the assembly that drives the transmission gear along the output shaft.

The shaft bearings (purple in cross-section) ensure their rotation.

Typical manifestations of Niva gearbox breakdowns

Repair of the Niva (5-speed) gearbox in each specific case depends on the location, number, and complexity of breakdowns.

It should be noted that symptoms in different cases may be similar. Thus, it is impossible to accurately determine the root of the problem based on sound effects alone. Accordingly, if there are any transmission malfunctions, you cannot do without a comprehensive diagnosis of the transmission unit in a specialized workshop.

Transmission malfunctions

The gearbox, in its basic design, is a gearbox with a variable gear ratio. Since this is a complex device, there may be several reasons for malfunctions. A gearbox failure can be diagnosed by the following signs:

1. It is impossible to engage the gear;
2. It is impossible to turn off the transmission;
3. The engaged gear is not fixed (the speed is knocked out);
4. The gear is engaged with difficulty and a characteristic crunch;
5. During movement, extraneous noises are heard and vibration is felt.

All possible malfunctions in the trivial classification are divided into malfunctions of the box itself and malfunction of the gear selection mechanism. The first type includes:

• failure of synchronizers;
• gear wear;
• failure of shaft bearings;
• loosening of the nut holding the gear;
• seals leaking.

Resource of transmission elements

With proper maintenance, all transmission elements have service lives that comply with the regulations. The existing stereotype about unreliability is not confirmed either documentary or practically. Until now, the Chevrolet Niva remains one of the most popular cars on the market. The owners claim that the car is taking care of its 200,000 km, which the plant lays down as a resource. This means that the transmission resource is determined by the manufacturer and cannot be less than 200,000 km.

A car with honest all-wheel drive for little money is a rarity in the modern market. That is why the Chevrolet Niva is in stable demand, both new and used. The simple and reliable all-wheel drive system of this car does not cause any particular difficulties in repair and maintenance, and to eliminate any malfunctions it is enough to know the architecture, design and operating principle of the main transmission components.

Maintenance Recommendations

The cause of the malfunction may be the exhaustion of the intended resource, but most often it lies in non-compliance with basic recommendations for operation and maintenance. Routine maintenance includes only timely replacement of transmission lubricant. It needs to be changed every 40 - 45 thousand kilometers.

Repairing a box is an expensive proposition. It often has to be carried out at a service station, so it is necessary to periodically check the oil level in the gearbox and inspect the crankcase for leaks.
