About important characteristics

Through drive 41 and 5, located on the front wheels, torque from this product is transmitted to the drive wheels. Disassembling the gearbox is carried out in different ways, depending on the design of the part.

For example, the main malfunctions of the four-stage option may involve working with the following parts:

1. Drive design that helps change gears.
2. Differential.
3. The most important detail of the transfer.
4. The reverse gear has its own intermediate gear, it is located on a separate axis.
5. Two synchronizers.
6. No design can do without secondary and primary shafts.
7. Carter 1.

An aluminum-based alloy is always used to make the crankcase. This must also be taken into account if gearbox noise elimination is required. The back cover helps hide everything. A breather is pressed into its socket. The bearing housings are located at the rear. There are also two holes that are closed with plugs. The secrets of repair are to work correctly with each of the elements.

The primary shaft is located in the crankcase and is mounted on two bearings. This shaft itself is made in the form of gears and reverse gears, a gear block.

Replacing a gearbox bearing requires interaction with such devices.

Reverse speed repairs must take into account that the secondary shaft and the gear on the main gear create a single composition. It rotates in the space between the roller and ball bearings. The gears responsible for 4,3, 2 and 1 gears can be found on the belts of the secondary shaft, on needle-type bearings. A detailed repair manual will also tell you that the splines on which the hubs are attached to the 12 synchronizers are cut using 2 small-sized belts.

All elements of the secondary shaft:

1 – nut; 2 – ball bearing; 3 – thrust washer; 4 – bearing sleeve; 5 – needle bearing; 6 – 4th gear gear; 7 – bearing spacer ring; 8 – synchronizer blocking ring; 9 – sliding clutch for synchronizer of 3rd and 4th gears; 10 – sliding coupling hub; 11 – third gear gear; 12 – retaining ring; 13 – thrust half-rings of the secondary shaft; 14 – 2nd gear gear; 15 – sliding clutch for synchronizer of 1st and 2nd gears with reverse gear; 16 – retaining ring of the synchronizer hub; 17 – hub of the sliding clutch for the synchronizer of 1st and 2nd gears; 18 – synchronizer spring; 19 – cracker; 20 – retainer; 21 – 1st gear gear; 22 – roller bearing; 23* – thrust washer; 24* – bearing sleeve; 25* – 5th gear gear; 26* – sliding clutch hub; 27* – sliding clutch for 5th gear synchronizer; 28* – thrust plate.

From 23 to 28 the parts of the VAZ 2108 five-speed gearbox are marked.

Each gear must have two teeth:

1. Straight-toothed.
2. Helical.

Crown designs with oblique teeth provide constant traction for the gears on the input shaft. When the gear is engaged, a connection occurs between the synchronizing clutches and the rims, which have straight teeth. This is also part of such a design as the gear selection mechanism at the gearbox.

Repairing the backstage affects other parts. The gears switch silently to each other thanks to the work of the synchronizer. On the primary and secondary shafts, the angular speeds for the gears are constantly equalized to achieve the desired result. The primary and secondary shafts themselves contain several elements. Each transmission repair diagram contains references to them.

• Each gear has a ring gear.
• The latch operates on springs.
• Three crackers with balls.
• Two Rings responsible for blocking.
• Part of the coupling that can slide.
• A hub mounted on the splines of the secondary shaft.

Where can I get my gearbox repaired? You can do it in your own garage - it’s a fairly simple job. Different types of synchronizers may be found in different gears, but they are not very different from each other.

Installation and removal process

After studying the device, car owners are wondering how to remove the gearbox on a VAZ 2108. Installing and dismantling the gearbox should not cause difficulties if you follow the steps.

• The car is installed on an inspection ditch or a lift. The engine hood must be raised. This position is fixed.
• Self-repair of the gearbox requires that you carefully examine the engine and its internal compartment.
• The battery and other wires should not be together either. The same applies to the top dead center sensor, relay on the traction type starter.
• Next, the speedometer drive housing is disconnected from the cable of the same drive. The design of the VAZ 2108 gearbox is such that to solve this problem it is necessary to unscrew the union nut.
• It is necessary to make sure that the wire with ground and the location of the clutch housing are separate.
• The sensor indicating the dead top point must be installed separately from the crankcase responsible for the clutch.
• The cable should no longer be connected to the fork that disengages the clutch.
• The next step: unscrewing the part of the structure where the top bolts and nuts are located. The bracket for lifting the power unit should be located on the left side of the stud responsible for fastening it to the intake manifold.
• Repairing the secondary shaft of the gearbox involves installing a cross member with serial number 67. 7820. 9514 on the gutters. The crossbar is hooked onto a special bracket. The bracket itself is usually installed on a stud in the intake manifold. Any type of power unit is hung in the form of a hoist if there is no crossbar.

Details of a disassembled gearbox from a VAZ 2108.
Maintenance of the gearbox involves work related to removal, which is carried out in the lower part of the car.

1. The repair of the gearbox cushion and other parts begins by removing the lower cover of the clutch housing and the engine mudguard.
2. When overhauling the VAZ 21083 gearbox, it is necessary to completely drain the oil that may be inside the gearbox.
3. Disconnecting the wires is mandatory for the light switch responsible for reverse.
4. After this, when tuning the VAZ gearbox, you can loosen the clamp. The rod is disconnected from the gear selection rod hinge.
5. The mount has a stud nut. She also turns away.
6. Replacing the transmission requires that the ball joints at the control arm be completely disconnected.
7. Defective gearbox means that you will need to knock out one hinge from the side gear. To do this, you can buy a special lift 67. 7801. 9524. Or use a special hammer, it will help damage the hinge inside, or rather its body, passing through the block part. Taking a technological mandrel or plug, you can understand that the semi-axial gear is easily fixed to the structure. The box repair book will become an indispensable assistant.
8. At the next stage, the second hinge is completely knocked out. If you study the transmission repair instructions, you will understand that this step cannot be avoided.
9. The wheel drive shafts are moved to the side. The six-speed gearbox is assembled in the reverse order.

How to reduce play in the gearshift lever on a VAZ 2109

If you are the owner of a front-wheel drive VAZ car (2108, 2109, 21099, 2110), then you probably paid attention to the increased free play of the gear lever, which feels like a loose gearshift handle and leads to unclear engagement when selecting gears.
We can say that this is a disease of these models, which lies in the standard gearbox of the gearshift lever. You can eliminate this drawback and modify the gear shift mechanism in the simplest way by replacing the standard gearbox driveshaft with a similar part from the Lada Kalina. By the way, you can do this modification yourself. For this modification, we need the gearbox driveshaft itself from the VAZ 1118 Kalina; we purchase it complete with a boot, because The standard boot of the VAZ 2109 will not fit in size.

Transmission cardan from Kalina

Comparison of VAZ 2109 and Lada Kalina gearbox hinges We will also need 10 and 13 keys, a hammer, a slotted screwdriver and an assistant, which will be useful at the final stage of work when adjusting the position of the gearshift lever.

We will carry out the work in a pit or overpass.

Loosen the clamp on the gearshift drive rod using 13mm wrenches, and remove the hinge from the rod.

1 — fixing bolt (10); 2 — clamp bolt (at 13); 3 — standard VAZ 2109 gear selection joint; 4 — boot Then we remove or bend the corner of the boot, and using a 10mm wrench, unscrew the locking bolt on the cardan and knock it off the shaft with gentle blows of a hammer. This bolt is very reluctant to turn off, since it is mounted on a thread lock to avoid spontaneous unscrewing due to vibration. At this stage, you can also replace the gear selector shaft oil seal if oil leaks are noticed from under the old one.

When the old part is dismantled, you can begin installing the new one. Having first put on the boot, we place the cardan on the gear selection rod (the one that comes from the box). In this case, the fixing bolt must, when screwed in, fall into a special recess under it on the rod. Then tighten the bolt and pull the boot onto the cardan. It is highly advisable to coat the bolt thread with thread locker so that it does not unscrew due to vibration.

Then we put the gearbox shift drive rod on the cardan rod, but do not tighten the clamp yet. Perhaps someone will have to shorten the rod of the Kalinovsky cardan by about 1.5 cm, since it is longer than the standard one.

Now you need to adjust the position of the lever. To do this, we involve an assistant who sits in the driver’s seat and moves the gearshift knob to the optimal position for adjustment. Typically the lever is centered and moved slightly to the right. In this position of the lever, we tighten the clamp while the assistant holds the lever in this position.

Now all that remains is to check the correct operation of the gear shift lever, and if something is not satisfactory, carry out the adjustment again.

In most cases, the feeling from such a modification is as if the box had been replaced: the lever does not dangle, the free play is minimal. But even more positive changes are noticeable on the go. Now the choice of gears occurs more comfortably and clearly, almost like in foreign cars!

Some maintenance tips

Before carrying out a major overhaul of the VAZ gearbox, it is necessary to completely clean the parts inside. Use a brush or scraper to remove all deposits. A strong jet of air is suitable for washing and blowing. The gaps of the gearbox gear are also completely cleaned.

Repairing a gearbox transmission is not as difficult as it might seem. And transmission breakdowns are not as terrible as you might think at first glance. It is enough to carefully study the transmission repair manual in order to perform all the necessary work at home.

How to remove a VAZ 2109 box

Removing the VAZ 2109 box is quite problematic. However, in fairness, it is worth noting that the clutch can be replaced even with the box not completely removed, but only slightly moved to the side.

But in cases where it is necessary to completely overhaul the gearbox, it must be removed. To do this, it is not necessary to have an overpass or a hole; it will be enough to raise the front part of the car higher (20 centimeters above the ground so that there are wheels).

In this state, you can remove the box without much difficulty. But you will need a tool and a little knowledge before you remove the VAZ 2109 box with your own hands, without resorting to outside help.

The procedure for removing the VAZ 2109 box

To begin, place chocks under the rear wheels and remove the battery. This must be done before removing the box of the VAZ 2109. Raise the entire front part with a jack. First one side, then the other.

Remove the wheels one by one and install reliable supports. If the repair is carried out at home, then a thick stump will work as supports. It is advisable to use wood; do not even think about installing bricks.

If you doubt the reliability of the support, you can install a pair of wheels nearby. Now remove the engine protection, open the hood, and completely drain the gearbox oil. Removing the VAZ 2109 box is impossible without this.

Now the most unpleasant thing is tedious and painstaking work, which is complicated by licked heads of bolts and nuts, and rust on them. After draining the oil, you need to remove the left grenade.

To do this, unscrew the two bolts that secure the ball joint of the left wheel to the hub and unscrew the nut, after removing the cotter pin, on the steering end. Now take a small chisel and a hammer. Place the chisel between the gearbox housing and the internal grenade. Apply short blows so that the CV joint comes out of the differential.

When it comes out, insert a plug in its place - a piece of pipe or a tightly rolled newspaper. That's it, now you can continue disassembling, since it is not yet possible to remove the box of the VAZ 2109, a lot of work still needs to be done.

Immediately unscrew the speedometer cable and loosen the bolt on the rocker, remove it from the axle. Unscrew the nuts and bolt securing the bracket on which the clutch cable is located. Remove the latter by pulling it towards the cooling radiator.

Disconnect the wire from the reverse sensor and remove the starter, first disconnecting two wires from it. Proceed to the most difficult stage - unscrewing the nuts and bolts on the two pillows. The rear may even rust to the body, so penetrating lubricant must be used.

When you have finished, you can begin removing the VAZ 2109 box, just first install a platform under it so that it does not fall from a height to the ground. You can put a cross member on the car and hang the box from it.

Now unscrew the remaining three bolts and one nut that secure the gearbox to the engine block. For convenience, remove the right inner CV joint. Using a crowbar, begin to pull out the gearbox; its input shaft should easily come out of the splines. Carefully, so as not to damage it, lower it to the ground. That's it, now the removal of the VAZ 2109 box is completed, you can repair or replace it.
