Tools

a set of keys;
Screwdriver Set;
WD-40 fluid in case you can’t unscrew some part;

Rust converter WD-40
container for draining old transmission oil; new oil (if the replacement was carried out a long time ago); rags; board.

Gearbox VAZ 2114 disassembled

Stages

Since you will have to work under the car, it is better to place the VAZ 2114 car on a pit or overpass; a car lift would be a good solution, otherwise you will have to resort to jacks.

First you need to remove the terminals and remove the battery. Drain the oil from the gearbox into a prepared container by unscrewing the drain plug. We remove the starter. Remove the clutch cable. We disconnect the block with wires from the speed sensor, after compressing the spring. We unscrew the bolt attaching the ignition bracket to the gearbox. Then unscrew the remaining bolts. Under the car we find and disconnect the block of wires leading to the reverse sensor. Unscrew the bolts securing the linkage bracket to the gearbox. Having first loosened the gear shift rod clamp, we pull it out, pushing it back. Dismantling the wheel drives

You can leave the right one. In order for the gearbox to be removed without any complications, unscrew the bolts with which the left ball joint is attached to the steering knuckle. We disconnect the lower mount of the gearbox to the engine - sometimes you can get by by simply loosening the tightening of the bracket. After unscrewing the bolts, remove the transmission housing cover. Unscrew the bolt on the left of the gearbox. We carefully and carefully hang the engine using a board or other device. At the bottom of the car, unscrew the nut securing the left motor mount. We unscrew the two nuts with which the rear motor mount is attached to the body. We unscrew the two bolts with which the rear engine support is attached to the transmission (the second key is used to keep the nuts from turning), and remove the support. We move the box along the guides. This completes the process of removing the box; after completing all the necessary tasks, assembly occurs in the reverse order. When you put the box in place, do not forget to adjust the clutch and fill it with new oil.

Gearbox device

Gearbox removed and slightly disassembled

Before starting the process, it is necessary to study the structure of the gearbox, as well as its design. This is necessary in order to determine the reasons why the unit needs to be dismantled, as well as to determine the mounting fasteners.

Transmission removal process

When the design of the element has become clear, you can proceed directly to the process of removing the gearbox. It is worth noting that this procedure may be associated with unit repair or auxiliary operations, such as, for example, clutch replacement. So, let's consider the sequence of actions:

First, you need to install the car on the inspection hole, since the gearbox is removed downwards.
We remove the “minus terminal” to de-energize the car.
We dismantle the engine protection from below, if present.
Remove the front wheels.
Disconnect the speedometer and clutch cables.
Next, you need to disable the rocker drive.
On the gearbox side, the engine mount must be removed.
Now that the preparatory operations have been completed, let's move on to removing the necessary assembly. Drain the oil from the gearbox.
We remove the internal CV joints from their seats.
After dismantling the fasteners, disconnect the gearbox from the engine.
We dismantle the unit completely.
If necessary, reassemble in the reverse order.

Reasons for dismantling

Gear selection mechanism removed from the gearbox

As mentioned earlier, the gearbox is dismantled for repair and restoration operations. Perhaps this is the main reason, but it is worth considering the issue of removing the unit in more detail:

The first and main reason for which removal of the gearbox will be required is the repair of this unit itself.
Replacing the clutch becomes the second main reason for dismantling the gearbox.
Along with the previous reasons, removal of the unit will be required when completely dismantling the main power unit.
Other reasons why it may be necessary to dismantle the gearbox, such as: repair of the front part of the body after an accident, slipway work, repair of the chassis and failure, as well as others.

Dismantling

To dismantle the box, we recommend that you rely on the instructions, strictly follow the sequence and reinforce your skills with visual videos.

Disconnect the negative terminal from the battery and drain the oil from the gearbox system.
Unscrew the bolts that hold the crankcase guard in place and remove it.
Disconnect the ground (wire) from the clutch housing.
At the end of the clutch cable, loosen the tension on the nuts slightly.
Remove the cable end from the clutch lever.
Disconnect the block from the traction relay.
Disconnect the wire going to the starter traction relay.
Dismantle the starter itself directly.
Disconnect the drive rod from the joint tip. We are talking about traction, which switches gears.
Disconnect the cable from the car's speedometer drive.
Unscrew the tie rod ball joint.
Remove and press the steering rod hinge pin out of the strut swing arm.
The shank of the inner CV joint of the front wheel drive should be pressed out and moved to the side.
Disconnect the second CV joint.
Remove the clutch housing shield.
Release the gearbox from the fasteners holding it to the engine.
Remove the box.

Carefully remove the gearbox
Be sure to move it horizontally away from the engine before directly removing the gearbox. Then disengage the input shaft. Be careful not to damage the clutch spring petals.

Inspection and repair

After dismantling, parts and assemblies are cleaned and their condition is checked. The crankcase and clutch should be free of chips and cracks. The sliding surfaces are inspected for signs of wear or damage. The bearing clearance should not be more than 0.05 mm. The wear of the seals should not exceed 1 mm. The teeth and landing shafts must be free of chips, cracks and nicks. The shafts must not have any dents. If defects are found, the parts should be replaced with new ones.

If you replace or repair the gearbox yourself, the warranty on the unit will be lost. It is retained only when serviced at certified service stations.

If you need to replace the VAZ 2114 gearbox, you can save money and install a rebuilt unit. It will cost 30-70% less than new. If you decide to make such a purchase, choose only proven companies that have been operating on the market for more than one year.

Malfunctions and their elimination

Gearbox repair largely depends on the nature and type of fault. There are several options for the breakdown of this unit, in each of which appropriate actions should be taken to eliminate them.

Malfunction

Possible reasons

What do we have to do

There is noise in the gearbox

The teeth on the gears are worn out;
Bearings are worn out;
The oil level in the gearbox has decreased

Add oil;
Replace worn bearings;
Replace seals if necessary

Gears are difficult to shift

The clutch is not fully depressed;
The rod that controls the gear shift mechanism has become deformed;
The integrity of the jet thrust has been compromised;
The joint or rod that selects the gear is loose;
The speed change drive is incorrectly adjusted;
The plastic components of the gear shift drive are broken

Try straightening the rods. If this is not possible, replace them;
Tighten the mounting screws more tightly;
Adjust the gear shift drive;
Replace damaged components

Spontaneous gear disengagement occurs

The ends of the synchronizer teeth on the gear and clutch are damaged or worn;
Cracks appeared, the rubber on the rear supports delaminated;
The gear shift drive was adjusted incorrectly;
The traction guard was not tightened correctly, which is why the gear is not engaged completely

Replace worn, deformed elements;
Correct the position of the rod casing;
Adjust the drive

Gears are switched on with noise and crackling

The clutch does not disengage completely;
The locking ring of the gear synchronizer, which is engaged, is worn out

There is an oil leak from the gearbox

Wear of the input shaft oil seal; Wear of the rod
speed selection;
Breakage of the speedometer drive shaft seal;
The cover on the gearbox or crankcase is loose;
The sealant under the gearbox cover is damaged;
The drain hole closure is loose

Replace gaskets, use new sealant and gaskets;
Tighten all existing fasteners;
Check the condition of the drain plug

In most cases, problems with the gearbox are eliminated by dismantling and disassembling it. Do not take on this type of work without the proper skills and experience.

Repair and replacement

It is quite difficult for novice motorists to even simply determine why their gearbox is not working. What can we say about replacing the gearbox seal on a VAZ 2114, which requires a certain skill and knowledge in the field of car repair.

Unfortunately, if you ignore the initial signs of a gearbox malfunction, this may result in a full-fledged need to replace the entire unit. Many are even afraid to ask the current cost of a new gearbox for the “fourteenth” model. But we will say. Today such a unit will cost you at least 15 thousand rubles. Moreover, this price does not include installation services. Changing an entire gearbox yourself is not an easy task.

Another big disadvantage of replacing it yourself is the lack of a warranty. The factory will only provide it to you if the replacement is performed by a certified service station. So we strongly recommend that you contact an official dealer if it comes down to replacing the box.

Let's be frank. Situations in which a car is rendered unsuitable for transmission repair are very rare. Most often, something like replacing the gear selector rod seal on a VAZ 2114, gears, levers and other components is required.

It is difficult to carry out diagnostics on your own in a garage environment. To correctly identify a breakdown, you will need at least a lift and a driver’s extensive experience in car repair. But it is best to carry out diagnostics at a car service center with the appropriate equipment. Whether you entrust them with the repairs or handle this stage yourself is up to you.

The cost of repairing a gearbox on a VAZ 2114 is influenced by several factors:

Location;
Skill level of the craftsmen;
Clauses of the concluded contract for the replacement or repair of the gearbox;
Level of car service (regular garage-type service station or full-fledged car service with a large staff and new equipment).

Gear shift mechanism

The gearshift mechanism is usually mounted in gearbox covers and is used to select, engage, and disengage gears. In addition, devices are installed in the gear shift mechanism that prevent the inclusion of two gears at the same time and prevent spontaneous gear shifting.

The main requirements for this mechanism are ease and simplicity of gearbox control, noiseless and smooth gear shifting, reliable locking of the engaged gear, prevention of simultaneous engagement of two or more gears, as well as protection from engaging a gear opposite to the vehicle's movement while moving. In addition, the activation mechanism must be reliable, durable, not requiring complex adjustments and easy to maintain. Malfunctions of the gear shift mechanism can lead to damage to parts and failure of such an expensive unit as a gearbox.

***

The gearbox shift mechanism of a truck (Fig. 1, a) consists of three rods, three forks, three clamps with balls, a fuse for engaging first gear and reverse gear and a locking device. Rods 8, 9, 11 are located in the holes of the internal bosses of the crankcase cover 1. Forks 5, 7, 10 are attached to them, connected to the synchronizer carriages and to the movable gear wheel for engaging first gear and reverse gear.

Clamps 4 hold the rods in the neutral or engaged position, which prevents spontaneous gear disengagement. Each retainer is a ball with a spring installed above the rods in special sockets in the crankcase cover. The rods for the clamp balls have special grooves (holes). Moving the rod with the fork, and therefore the synchronizer, is only possible when force is applied by the driver, as a result of which the ball sinks into its seat.

The locking device prevents two gears from being engaged simultaneously. It consists of a pin 12 and two pairs of balls 6 located between the rods in a special horizontal channel of the crankcase cover. When any rod moves, the other two are locked with balls that fit into the corresponding grooves on the slides.

In order to prevent accidental engagement of reverse gear or first gear when the vehicle is moving, a fuse is mounted in the wall of the gearbox cover, consisting of a bushing, a ring with a spring 3 and a stop. To engage first gear or reverse gear, it is necessary to press the fuse spring all the way, for which some force is applied to the driver control lever.

***

The gear shift mechanism of a passenger car (Fig. 1, b) is arranged as follows. Rod 14 of the third and fourth gear shift fork is installed in the holes of the front and rear walls of the crankcase, and rods 13 and 16 are installed in the holes of the rear wall and crankcase boss.

The 15, 21, 23 gear shift forks are secured with a bolt on each rod. To hold the rods in the neutral position and in one of the extreme positions when the gear is engaged, they have three sockets, to which the retainer ball 20 is pressed by a spring 19. The clamps are located in bushings and are closed with a cover 18. In the head of each rod there is a groove into which the lower end of the gear shift lever fits.

The locking device consists of three locking blocks 17. The two outer blocks are installed in the holes of the rear wall of the crankcase, and the middle block is in the hole of the rod 14. When the rod 13 or 16 moves, it squeezes out a block that fits into the socket of the middle rod and at the same time presses the other through the middle block cracker to the socket of the opposite rod. This way, these rods will be locked in the neutral position. When moving the middle rod 14, two crackers are squeezed out at once and the outer rods 13 and 16 are fixed.

How to remove the gearbox?

The VAZ 2114 and other models of the LADA SAMARA family range are equipped with a five-speed gearbox combined with a differential and final drive. In principle, the box from the VAZ 2114 is no different from the VAZ 2108. The only thing is that the VAZ 2108 does not have a dipstick, and acceleration on it will be faster.

You will need to remove the box to replace the clutch, clutch bearings, and repair the box.

How to remove the gearbox?

To remove the gearbox we will need:

set of keys;
screwdrivers;
assistant;
wd-40;
board or other hanging equipment.

First of all, remove the terminals from the battery and take it out. We drain the oil from the gearbox (How to drain the oil from a gearbox?) and remove the starter (How to remove the starter on a VAZ 2114?). As you work, if you can’t unscrew any fastening or bolt, then don’t forget to use wd-40.

1. Place the car on the overpass (pit) and remove the crankcase protection by unscrewing 3 fasteners.

2. Next we need to remove the clutch cable from the clutch release fork. Then we pull it out of the bracket on the box.

For the purpose of complete understanding for the reader, the slides refer to points 3-19 in order except point 14, where you need to hang the engine.

3. Next you need to remove the wire block from the speed sensor (DS). The block is secured by a spring, so to remove it, compress the spring.

4. Unscrew bolt 1 securing the ignition module bracket to our gearbox. And bolt numbers 2 and 3 shown in the picture.

5. We climb under the car and find the wiring block for the reverse sensor. Let's disconnect it.

6. Then unscrew the 2 bolts securing the torque arm to the box.

7. Loosen the clamp of the transmission gear shift rod. We remove the rod from the gear selection rod hinge by moving it back.

8. Remove the wheel drives. Tie the plug inserted in place of one of the drives with a rope or wire so that it does not fall out when removing the box. The right drive does not need to be completely removed. We disconnect it from the box and hang it in the body, first moving it to the side.

9. So that the box can be removed without additional difficulties, unscrew the two bolts of the left ball joint from the steering knuckle.

10. Unscrew the lower right mount of the gearbox to the engine (number 1 in the figure). The support bracket (number 2 in the figure) is needed from the stud.

11. If necessary, just loosen the fastening of the bracket.

12. Unscrew the 3 fastening bolts, remove the cover (number 1) of the clutch housing (number 2).

13. Unscrew the bolt of the lower left gearbox mounting

14. Hanging the engine using a board or other device

15. Unscrew the nut securing the left power unit support (from the bottom of the car)

16. Unscrew the 2 nuts securing the rear support of the power unit to the body.

17. Unscrew the 2 bolts securing the rear support of the power unit to the gearbox, holding the nuts from turning with a second wrench, and remove the support.

18. Inserting a screwdriver between the clutch housing and the cylinder block, slide the gearbox off the guide bushings. Be sure to hold it while doing this.

19. Move the gearbox as far back as possible, passing the rear cover of the box over the front suspension brace (the input shaft should disengage from the clutch). If the input shaft cannot be disengaged from the clutch, push the engine to the side. Lower the front end of the box and remove it from under the car.

How to install the gearbox?

The gearbox must be installed in the reverse order. After installation, you need to adjust the clutch drive (How to adjust the clutch drive?) and the gearbox lever, and fill in the transmission oil.

To perform repairs associated with the dismantling and subsequent replacement of the mechanism, prepare a standard set of tools and perform the following sequence of actions:

After removing the decorative tunnel located between the front seats, remove the gear shift mechanism. The mechanism must be replaced if there are signs of wear, distortions, loose bushings and other defects.

Dismantling the box

If you can hear an incomprehensible noise in the gearbox, the car becomes difficult to change gears or does not want to move at all, you may need to remove this mechanism. Do-it-yourself repair of a VAZ 2109 vehicle can be done in any garage, having all the necessary tools at hand. The VAZ 2109 has a rather complicated gearbox removal, so you should prepare for this procedure in advance.

The box is located deep enough, so it is almost impossible to remove it alone. In this case, you may need special crowbars, the help of other people and some tools in order to properly disconnect it. In general, you can seek help from a service center, where the service will be carried out using special equipment. But, you can repair it yourself by removing it carefully without damaging other important parts.

How the box works

It has features that entirely depend on the configuration of the machine. This could be a four- or five-stage vase model. The structure of a four-speed gearbox is as follows:

1. Primary shaft;
2. Reverse gears, to which the front shaft is attached;
3. Synchronizers, 2 pieces;
4. Bearings placed on the secondary shaft;
5. Driven gear. Attached to the differential flange.

The element is controlled by a drive, rod, rod and ball joint. Only complete interaction of these parts can ensure full operation of the box.

Gearbox device

To determine the type of gear, there is an additional lever, which is attached to the inner end of the rod.

There are also axles in the body; a three-arm lever is attached to one of them. Its main purpose is to lock the bracket and bushing, which is necessary to ensure the strength and immobility of the mechanism.

The second axis is designed to fix the locking brackets from their rotation, passing through the center. In addition, there is a lock that prevents the box from loosening. The other axle also has a fork, which is necessary to engage the VAZ 2114 in reverse.

The five-stage type differs in the size of the shaft and the absence of a bushing in the element. Usually this is what is installed in the VAZ 2114, since the other one is not entirely practical to use. Like any spare part, a gearbox can also break down and fail.

The most common problems are:

Unknown noise: it may be caused by bearing failure or gear wear. In addition, you should play it safe and check the oil level;

The solution to the problem is to completely replace failed spare parts and add oil.

Difficulty shifting the VAZ 2115 gearbox: the drive rod may have become deformed. It would be a good idea to check how firmly all the screws are screwed on and how the box drive is adjusted correctly. There is a possibility of failure of plastic parts in the drive;

Solution: Strengthen the screws, adjust the drive, replace worn and failed parts, replace or correct the deformation of the rod.

Turning off the gearbox without the driver's participation: the cause may be damage to the teeth on the synchronizer, an incorrectly adjusted drive, or poor installation of the traction cover, which provokes incomplete engagement of the traction;

Solution: Adjust the drive and replace the covers, replace the failed spare parts.

Oil leak. The reason is still the same - wear of spare parts, which this time are oil seals, seals and hinge bodies

In addition, you need to pay attention to the strength of the fastening. If it becomes loose, it is necessary to tighten all the bolts and check the seals for damage;

Solution: Purchase new spare parts and replace them.

Where and how is it more profitable to buy a gearbox in case of its complete failure? Since the performance of the vehicle and safety depend on the VAZ 2114 gearbox, its technical condition must be taken very seriously.

That is why it is worth recalling that, like any element of the machine, the gearbox needs regular technical inspection. Saving on oil changes, untimely detection and replacement of breakdowns, complete ignorance of troubles with the machine’s mechanisms - all this leads to failure of the gearbox.

Don’t think that if you have a domestic car, that means you are lucky. The rise in prices for spare parts is indicated by the price of the box, which today ranges from 16 thousand rubles. up to 18 thousand rubles Add in fees for removal, installation and maintenance - the cost will be impressive.

Used manual transmission for Lada 2114

An easier option would be to purchase a used item. No one will give a guarantee that there are no defects in it, but the purchase will cost half as much.

The best option is to carry out timely maintenance and repair of the box. This approach will not only save the budget, but will extend the life of the parts.

VAZ-2114 gearbox device

To ensure that the engine can operate in optimal modes when driving in various conditions, cars are equipped with gearboxes. This mechanism is capable of changing the amount of torque that is transmitted from the power unit to the drive wheels at the moment of starting from a standstill or at the moment of gaining speed. The mechanism consists of several main elements. This is a set of rotating shafts and gears, transmission links.

The mechanism housing includes a clutch housing, gearbox housing, and rear cover. The main pair is located inside the mechanism. There is a differential and gears, due to which the gear ratios change. This car uses a slightly modified mechanism that was left over from the VAZ-2108. The difference is in the other main pair.

In a gearbox, this is the main gear or the main, input shaft. It is designed to reduce engine speed. The main gear can reduce the number of revolutions in a ratio of 1 to 4. Thus, if the engine speed is 2 thousand, then the speed of rotation of the main pair will be 500 rpm.

On the VAZ-2114, the gearbox in the main pair has a standard rating of 3.7. This figure is stable. But if you change it, you can adjust the dynamic characteristics of the car.

The maximum speed and acceleration capabilities of the car depend on the size of the main pair. It is this element that affects the transmission length. If you change the main pair, you can adjust the length of all gears. Acceleration and top speed also change.

On the VAZ-2109 the main pair is 3.9. Due to this, the maximum speed on this car is lower, but the car accelerates better.

The VAZ-2114 gearbox is a five-speed, mechanical, synchronized gearbox. The main gear is connected to the differential unit. The gears from first to fourth are made in the form of a block and mounted on the input shaft of the box. The fifth block of drive gears is mounted. On the VAZ-2114, the gearbox also has a secondary shaft. Driven gears are installed on it. The shaft itself is connected to the drive gear through the main pair.

Device

To understand the essence of repairing, disassembling and assembling a gearbox, first of all you need to get acquainted with its structure. In the case of the VAZ 2109, the box structure is as follows:

On the input shaft there is a block of drive gears that are in constant mesh with the driven gears of the gears when moving forward;
The second shaft has driven gears with needle bearings. There is also a pair of synchronizers located there;
The secondary shaft is created together with the drive gear of the main transmission;
The driven gear of the main gear is attached to the flange of the two-pinion differential box;
Differential bearings are always mounted with interference, which is adjusted by selecting rings of different thicknesses.

Diagnostics and minor repairs of the device

The gearbox, like many car components, sometimes malfunctions and requires maintenance. There are several main reasons that lead to problems. If you hear extraneous noise in a VAZ gearbox, it may be due to wear on the gear teeth or bearings. The box may make noise if the oil level is low. To solve the problem, it is necessary to replace worn mechanisms, oil seals and bring the oil level to normal.

Problems when shifting gears. In this case, it is necessary to inspect the control drive rods for wear. You should check the reliability of the hinge mounting and the gearbox lever rod. Incorrect debugging of the switching drive or breakdown of plastic parts of the assembly can also cause a similar problem. To troubleshoot problems, you need to adjust or replace the rod, tighten the screws and adjust the drive, and replace faulty parts.

Unplug the box.
Drain the oil and disconnect the starter.
Remove the crankcase protection.
Disconnect the fastening cable and remove it from the bracket.
Remove the wires by pressing the spring.
Remove the reverse control wires.
Unhook the rod from the hinges, moving it back a little.
Remove the clutch cover.
Hold the box and unscrew the remaining nuts.

Features of the device and structure of the transmission mechanism

The fourteenth model is equipped with a five-speed gearbox similar to the unit installed on the G8, with the exception of the main pair.

According to consumer reviews, the lack of quality of the fourteenth gearbox includes the selection of gear ratios: a very short first speed and a long second. This drawback leads to a loss of vehicle dynamics when switching from first to second gear during acceleration.

The gearbox housing, rear cover and clutch housing are the main parts of the gearbox design structure.

Internal device groups:

first (main pair);
second (differential with gear ratios).

Main couple

The drive shaft functionality reduces the speed transmitted from the engine to the crankshaft. The transmission coefficient is 3.7. Thus, the main pair of the “fourteenth” is capable of reducing the indicated speed by approximately 4 times. The length of the gears can be changed by controlling the main pair mechanism. What affects acceleration and the maximum possible speed limit of the vehicle.

Differential with gear ratios

The differential gear ratios of the stock VAZ 2114 gearbox include: 3.636 (first speed number); 1.95 (second speed number); 1.357 (third speed number); 0.941 (fourth speed number); 0.784 (fifth speed number) and 3.53 (reverse speed number).

Having an idea of the structural features of the gearbox mechanism, it is necessary to begin preparing tools, materials and tools that will be useful during the removal and disassembly of the box.

High-quality oil is the key to reliable operation of the gearbox

Repair manual for VAZ 2108, 2109, 2114, 2115 Wires and fuses
Despite the unpretentiousness of domestic cars, their units require proper care and prevention. For proper operation of the gearbox, high-quality oil is necessary. The best option for the VAZ 2114 gearbox is mineral oil. Its only drawback is the high price. Of the synthetic and semi-synthetic options, it is better to choose the first one.

When using it, you need to clean the seals in time. Oil category GL-4 is the most suitable type for the VAZ 2114. To ensure reliable and uninterrupted operation of the unit, it is necessary to check the oil level at least 3 times a week. The easiest way to check is to use a dipstick. To do this, you need to place the car on a flat surface.

15-20 minutes after stopping, pull out the dipstick, wipe it dry and insert it back. Then remove the dipstick and record the oil level, which should be at the maximum level. If the amount of oil is insufficient, top it up and check the level again. Due to the fact that the fifth gear is located higher than the others, it often lacks lubrication.

Experts recommend maintaining the oil level slightly above the maximum mark, which will extend the life of the gearbox. It is better to entrust the oil change to specialists, because the gearbox is one of the main units of the vehicle. You can carry out the procedure yourself, but you should adhere to the following recommendations.

In case of replacing oil of one brand with another, the box must be flushed.
Place the machine on the inspection hole.
Remove the cap and clean it.
Clean the breather and its holes with a brush.
Prepare a container for draining and unscrew the dipstick.
Tighten the plug and fill in new oil through the dipstick socket.
Screw the dipstick and put on the cap.

The price of a gearbox for a VAZ 2114 with all parts and oil is quite high. There is no point in indicating a specific figure, since the price is constantly changing

But you shouldn’t skimp on this important device: not only the operation of the engine, but also the safety of the driver and passengers depends on the reliable operation of the gearbox. To save money, you can purchase a used box

But it is better to buy such a unit from a reliable supplier, otherwise there is no guarantee that the parts will not contain hidden defects and malfunctions.

Timely repairs and preventive measures allow VAZ 2114 owners to extend the service life and maintain the quality of the gearbox. This approach is the optimal solution for the uninterrupted operation of the unit and the engine as a whole.

Removal and Installation Guide

To conveniently dismantle the box from the car, you need to use a lift or inspection pit. It is extremely inconvenient to carry out work on a flat surface.

Having fixed the VAZ 2115 on the lift, you need to open the hood, remove the terminal from the battery and starter, disconnect the ground and the clutch cable. Next, having unscrewed the clutch and starter mounting bolts, we fix the exhaust manifold of the VAZ 2115 engine with a lifting mechanism bracket.

After installing the engine support safety crossbar, we move on to the bottom of the car. We remove the protection, then dismantle the clutch housing after draining all the oil. We disconnect the reverse sensor, loosen the clamps and remove the rod from the rod joint intended for changing gears. We unscrew the stud mounting the VAZ 2115 engine with the gearbox. Then we disconnect the steering knuckles from the ball knuckles and carefully remove the axle gear to avoid it getting into the crankcase. Having completed this operation, we knock out the second hinge, while moving the wheels in different directions. If it is not possible to disconnect the wheel drive from the axle shafts, the box is removed as an assembly. Using special equipment, press the hinge out of the axle gear. When you have everything in a suspended state, unscrew the remaining mounting bolts, having first positioned the hydraulic lift. Lower the engine slightly on the safety cross member and the gearbox will easily come down.

Removing the primary and secondary shafts

During removal and installation, do not allow the input shaft to press on the release spring petals. This may cause damage which will incur additional costs.

It is better to leave it to a specialist to disassemble the box itself and replace worn gears. If you have never done this before, it is better to refrain from experimenting. It is not difficult to disassemble it, but not everyone can assemble it without certain skills. Even experts sometimes make mistakes because of which they have to disassemble everything again.

When the box is repaired, do not forget to fill in special gear oil before installing it on the car. It is much more convenient to pour it on the ground. Oil must be filled strictly according to the level. High-quality oil will ensure uninterrupted operation of the box, while extending its service life for many years.

Installation occurs in complete reverse order. The main thing is not to forget to replace all the old retaining rings and before starting installation, lubricate the outer surface of the clutch sleeve of the bearing that disengages the clutch. After the installation is completed, all that remains is to adjust the clutch pedal travel and the drive that controls the gear shift mechanism.

Always change gears smoothly, fill in high-quality oil and your gearbox will serve trouble-free for many years.

Sequence of actions when repairing a gearbox on a VAZ 2109

How to replace the idle speed control on a VAZ 2108, 2109, 2114

When carrying out an operation such as manual transmission repair, you must adhere to the following sequence of actions:

It is necessary to remove the gearbox (it should be noted that repair of the gearbox on a VAZ 2107 is carried out approximately according to the same principle). After removing the gearbox, you need to clean it from dirt using a rag and diesel fuel. The oil level dipstick is removed, after which the clutch housing is installed vertically. The clutch cable bracket must be removed. Unscrew the corresponding nuts and remove the back cover.
It is necessary to unscrew the bolt securing the fifth gear fork. After this, you need to secure the shafts from turning and unscrew the nuts securing the primary and secondary shafts.
The fifth gear gear is removed along with the fork and synchronizer from the secondary shaft. The thrust plate is removed from the synchronizer, and the fork is removed from the coupling groove. Next, the gear and ring are removed, after which the bushing is removed.
The bushing is removed from the input shaft. Then you need to use an impact screwdriver to unscrew the four screws and remove the thrust washer from the secondary shaft.
The retaining rings of the shaft bearings are removed, after which the retainer balls are removed. The reverse locking plug is unscrewed, the O-ring is removed and the locking spring is removed. The box needs to be tilted and the locking ball removed.
You need to unscrew the twelve nuts and the crankcase mounting bolt. The gearbox housing should be separated from the clutch housing using a screwdriver. Subsequently, you need to unscrew the bolts of the gear shift forks (1-2, 3-4).
After the rods and forks are removed, you need to remove the reverse gear axis. It should be noted that gearbox repair includes, first of all, disassembling the unit. However, without this, inspecting spare parts and determining their performance is impossible.
Remove the intermediate gear, then remove the input and output shafts. The differential is removed from the clutch housing. Next you need to remove the gear mechanism. Then the gearbox is disassembled in the following sequence:
housing with speedometer drive gear,
reverse switch,
secondary shaft bearing,
sump,
input shaft bearing.
In general, repairing a gearbox on a VAZ 2109 consists of replacing all worn-out spare parts. In particular, it is definitely necessary to replace all pressed out bearings. So, at this stage of work it is necessary to press new front shaft bearings into the clutch housing.
After the gear rod is removed, you can repair the gearbox, that is, directly replace all damaged and worn components in the following sequence:
clutch housing (small damage can be cleaned with sandpaper),
after checking the bearing seats in the clutch housing, they must be replaced if their condition is unsatisfactory,
roller bearings,
gear shift rods,
axle seals,
input shaft oil seal,
magnet (it should be cleaned first),
The planes of the clutch and gearbox housings must be cleaned of old sealant. After which the gearbox is assembled.
The shafts are installed in the clutch housing. After that, all rubbing elements are generously lubricated with oil and the magnet is installed in place. Sealant should be applied to the gearbox housing and clutch housing. In addition, the gearbox oil may need to be changed. After this, the work is considered completed.
