6.2.4. Removal and installation of the transmission
The main malfunctions for which elimination it is necessary to remove the transmission from the car:
– raised (in comparison with habitual) noise;
– the complicated gear shifting;
– spontaneous switching off or indistinct inclusion of transfers;
– leak of oil through consolidations and laying.
Besides, the transmission is removed for replacement of a flywheel, coupling and a back epiploon of a bent shaft of the engine.
Useful tips
Work on removal and installation of the transmission is very labor-consuming therefore be previously surely convinced that its malfunctions are not caused by other reasons (insufficient level of oil, defects of the drive of coupling, weakening of fastening of a box, etc.).
The transmission quite heavy also has the form, inconvenient for keeping, therefore we recommend to remove it with the assistant.

It will be required to you: keys "on 10", "on 13", the screw-driver with a flat edge.
1. Install the car on the elevator or a viewing ditch.
2. Merge oil from the transmission (see. "Check of level and replacement of oil in the transmission") if you remove it for repair.
|
3. Disconnect internal hinges of drives of forward wheels from the transmission (see. "Removal and installation of drives of forward wheels").
|
4. Disconnect the sensor of provision of a bent shaft from a coupling case (see. "Sensors of a control system of the engine").
|
5. Disconnect blocks of plaits of wires from the backing light switch...
|
6.... and from the speed sensor, having squeezed spring clamps of blocks.
|
7. Disconnect a cable from the coupling switching off lever (see. "Replacement of a cable of the drive of switching off of coupling").
|
8. Remove a starter (see. "Removal and installation of a starter").
|
9. Unfasten the screw-driver a clamp of the hinge of draft of the choice of transfers...
|
10.... also disconnect the hinge from a spherical finger of the intermediate lever of the choice of transfers of the mechanism of the transmission.
|
11. Turn out a bolt of fastening of an arm on the transmission to the left back support of a suspension bracket of the power unit.
|
12. Unclench the screw-driver a spring clamp of draft of gear shifting...
|
13.... take a clamp from an opening of draft and disconnect draft from the gear shifting lever.
|
14. Unfasten a clamp of the hinge of intermediate draft of the choice of transfers...
|
15.... also disconnect draft from a spherical finger of the intermediate lever.
|
16. Turn out two bolts of fastening of the amplifier of the block of cylinders to a forward part of the power unit...
|
17.... two bolts of fastening to a back part...
|
18.... three bolts of fastening of the amplifier to a coupling case...
|
19.... also remove the amplifier.
|
20. Establish a reliable support under the engine, turn out the top bolt of fastening of an arm of a forward support of a suspension bracket of the power unit to a coupling case, turn off a nut of the lower bolt of fastening of an arm and take a bolt.
|
21. Turn out two bolts of fastening of the transmission to the engine located from the back party of the power unit...
|
22.... and two top bolts of fastening of the transmission to the engine.
|
23. Turn out three bolts of fastening of an arm of the left back support of a suspension bracket of the power unit to a case of the transmission and remove an arm.
|
24. Shift the transmission a little back and take from a gap between it and the block of cylinders a coupling case guard.
|
25. Shift a box as much as possible back to an exit of its main shaft from a nave of the conducted clutch plate, incline a back part of a box down and remove a box from the car.
|
26. Install the transmission and all removed details and knots as it should be, the return to removal.
Good advice
Before installation of the transmission we recommend to grease vents of a main shaft with a thin layer of refractory jellied lubricant.
|
27. Fill in oil in the transmission (see. "Check of level and dolivka of oil in the transmission") if it was merged before its removal.
