Do-it-yourself checkpoint repair on a Gazelle, necessary for visible problems with this node. Signs of a malfunction are difficulties with shifting gears, jumping out of speeds, noise in the gearbox. If any of these signs appear, it is simply necessary to repair the box. In some cases, this should be done immediately.

Ensure the integrity of the parts before the assembly process. Cracks, as well as the consequences of visible wear, are considered unacceptable. The bearings should slide into place with little effort. If there are small seizures on the surface of the shafts, you need to grind them with GOI paste. Mating parts should rotate without any interference.

All ball bearings must be replaced. Before assembling, you need to rinse the parts in kerosene or diesel fuel. It is advisable to install gaskets together with a sealant, this will avoid transmission oil leaks.

Conclusion... The transmission is constantly under load, so the wear of its parts is quite high. In this regard, people are often interested in whether it is possible to repair the checkpoint on the Gazelle with their own hands. In fact, there is nothing particularly scary in this node, if everything is done carefully, then you will not have any problems.

We remove the gearbox. We look at the article - "Removing and installing the checkpoint."

We wrap the filler and drain plugs in place.

Remove the power unit support.

Remove the reversing light switch.

We remove the speedometer drive.

We remove the clutch with the bearing and the foam rubber rings of the front cover.

Using a 12 key, unscrew the three bolts securing the bearing cover (the bolts are installed on the sealant).

Remove the cover with the gasket.

When installing it later, pay attention to the coincidence of the oil drainage channel in the cover and the holes in the crankcase.

Prying off with a screwdriver, remove the input shaft seal from the cover (when disassembling the gearbox, we replace all the cuffs, regardless of their condition).

Press in a new cuff with a mandrel or a head of a suitable diameter.

With the key "13" we unscrew and remove the bolt securing the bushing of the reverse gear axle to the front crankcase

Use a thin screwdriver to pry on and remove the retaining ring of the input shaft bearing

Turn the key "12" and remove the breather.

Using a 12 key, unscrew ten bolts connecting the front and rear crankcases (two bolts passing through the dowel sleeves are longer than the others).

11. Gently tapping with a hammer through the brass mandrel, undo the front and rear crankcases.

In this case, do not strike at the end of the input shaft, as the synchronizers will be damaged.

Disconnect the gearbox housings

Carefully, trying not to damage, remove the gasket

We take out the adjusting shims from the bore under the intermediate shaft bearing in the front crankcase (they may not be there). In this case, the axial clearance in the bearings is set only by the crankcase seal.

Repair of the Gazelle checkpoint is a difficult event for which you need to prepare in advance. The gearbox functions by transmitting torque to the wheels from the motor shaft. It should be understood that the slightest failure in the functioning of the transfer case can threaten your safety. If there is no service station nearby, you can repair the malfunction yourself. If you strictly follow the step-by-step instructions, even a novice motorist can carry out this procedure without any problems.

The Gazelle checkpoint is rightfully considered one of the most reliable and durable, but even they can become unusable due to high loads. In order for the replacement of the Gazelle gearbox to go without a hitch, you must know the materiel of the car, study the diagrams, be careful and patient, and also follow the safety rules and understand the principle of operation in the Gazelle 4x4 gearbox.

Repair of the Gazelle may be required in some cases:

• Difficulty shifting gears. Such a snag occurs due to the lack of fluid in the cylinder or due to the presence of air in the hydraulic actuator. In addition, you can check the locking bolts, which often require additional tightening, as well as the intermediate shaft of the gearbox. You can observe how the device jerks in neutral and the box howls. Another sign - in 4th gear, the fifth or second device makes a howl, a lot of noise;

• the inclusion of the gearbox occurs with noise and crackling at startup. In this case, the synchronizer block ring on the transfer case could be worn out or deformed. Also check the power take-off. It is advisable to replace the locking ring or the power take-off, and in order for the new element to rub in without problems, use lapping paste. In addition, check the condition of the input shaft, how the mortar works, whether the car was noisy in neutral;
