Five-speed gearbox device schematic VAZ 2113-2114-2115

Long-term use of a VAZ car can easily damage any part. The variable gearbox of the modern model 2115 is no exception. Especially if an inexperienced driver has been behind the wheel for a long time.

If the gears begin to engage poorly, jump out spontaneously, or the gearbox begins to make extraneous noise, you need to contact the dealer or make an appointment at the nearest service station. Any service station will gladly accept the next client, trying to squeeze the maximum amount out of him. As a rule, prices are always inflated and do not correspond to the quality of the work performed.

If you know a master, you can contact him. Typically, such masters take care of each client, always performing their work with high quality and much cheaper.

But, when you know at least a little about the structure of the box and are not afraid of getting dirty, it is better to do the repairs yourself. After all, having done everything yourself and poured high-quality oil, you will always be sure that it will not let you down at the most inopportune moment. The design of the domestic VAZ 2115 car is quite simple; it does not require certain skills and knowledge during maintenance.

Box removal process

Removing the VAZ 2114 box is quite simple, although there are some peculiarities, so it is still advisable to have an experienced partner next to you for the first time.

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.

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.

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.

Gearbox configurations

Below are the most successful gearbox configurations depending on the engine. For a more detailed selection, you can use a calculator on the Internet.

1. The most suitable gearbox configuration for a civilian naturally aspirated engine: 18 row gearbox + main pair 3.9.
2. The most suitable gearbox for a sports naturally aspirated engine: 7th row gearbox + main pair 4.3.
3. The most suitable gearbox configuration for a turbo civilian engine: row 104 + main pair 3.5.

The differential is two-satellite, the tension is adjusted by different thicknesses of the adjusting ring.

Sports cars often use a differential lock.

A differential lock is a mechanism that locks the differential so that both wheels rotate evenly. Initially, locking was used on SUVs to ensure that the front and rear axles rotated evenly.

In our case, screw locks are especially popular, because they are easily installed in the gearbox, increase cross-country ability on wet roads, and provide an advantage during acceleration due to uniform constant rotation of the wheels.

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.

Oil

AvtoVAZ recommends gear oil of the following category:

• API group: GL-4
• SAE viscosity grade: 75w90t (synthetic), 80w85 (mineral), 85w90 (semi-synthetic)
• Recommended brands of oil by the factory (it’s not a fact that it’s good, I personally haven’t used it, and you won’t find them in stores): Lada trans KP, Lukoil TM 4-12, new trans KP, Nordix supertrans RXS, trans KP, Slavneft TM- 4 and other rare brands that you often cannot find in the store.
• Oil filling volume in the gearbox – 3.3 l
• As for viscosity, I would recommend 75w90 (synthetic), because... the most universal, freezes less in winter, and in summer without problems. As for semi-synthetics, they are mainly made only by Russian manufacturers, so synthetics are recommended.
• Rumors that synthetics squeeze out the gasket are nothing like that. Everyone uses it, no one complains, you just need to keep an eye on the seals.
• The only disadvantage of synthetics is that the gearbox is a little noisier than with semi-synthetics.
• Operating experience:
• Castrol 75w90 – freezes slightly in winter, but does not drive in neutral.
• Shell Getribeoil EP 75w90 – you can start without pressing the clutch pedal.
• TNK 75w90 - similar to Shell
• In fact, the most important thing when choosing oil is not to fall for a fake, so buy from trusted sellers and official dealers.

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.

Main couple

The main pair is the main shaft (main gear). The main pair serves to reduce the speed transmitted from the engine. On average, the main pair reduces the number of revolutions by 4 times: the engine spins 4 thousand revolutions - the main pair 1 thousand revolutions. The main pair as standard has a gear ratio: 3.7. By changing the main pair, you can significantly change the dynamics of the car. Depending on the size of the main pair, you can change the length of all gears, hence the maximum speed and acceleration. (By the way, the “nine” has a 3.9 main pair, due to this it has a lower maximum speed, but is faster at acceleration).

Below are three graphs by which you can compare the speed at 5500 rpm of an engine with different main pairs. (Calculations are based on r15 wheels with a 195/50 profile - the same as r14 with a standard VAZ profile 175/65 or 180/60).

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.

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

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.

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

Gear ratios (row)

These are the gears of each gear, which also have their own size.

They characterize the speed of the car in one gear or another. The standard VAZ uses the following numbers:

Above are the specifications with standard parameters.

The standard series on 2114 is far from ideal. The first gear is too short, the second is too long. Due to this, there is a sharp drop in dynamics when switching from first to second. Not only is there a failure, but when switching sharply, the second speed synchronizer slowly dies.

Therefore, there are sports series where the gap between 1st and 2nd is removed, and not only: sports series are selected according to the type of engine. It could just be a good city engine, or a sports engine, or tailored for 402-meter racing. There are also “turbo” gears designed for a turbo engine.
