9.2.2. A transmission
THE GENERAL DATA

The transmission can be removed without engine removal. But in the majority a case removal is required only when it is necessary to replace a transmission, to restore or replace муфту. As it is impossible to repair a transmission with application of handicraft house means, in it is necessary to address in a repair truck, unit removal is more low described only.

Removal

PERFORMANCE ORDER
1. Disconnect from the plug of the storage battery a weight wire (–).
The prevention

The anticreeping code of radio is thus erased.


2. Cover with a suitable sheet material a back wall of a motor compartment that at lowering of a transmission not to damage isolating rug.

The prevention

At cars with additional system of heating at lowering of a transmission pay attention to that the hose with a cooling liquid around a back wall of a motor compartment was not damaged (arrow).


3. Raise the car, prop up a transmission a special automobile jack (in a repair truck) and wooden linings.
4. Remove the bottom protective cover of a motor compartment.
5. Unscrew the bearing of a shaft of the engine on a back cover of a transmission (arrow).
6. Unscrew an arm (1) support of the engine on the basis of a frame of a body (arrow).
7. Remove system of release of the fulfilled gases. Unscrew the holder (2) on a check point (marksman). In advance note position of a lining plate by compasses (describe a circle) that she could be established later again on a former place.
8. Unscrew the screen to the intermediate bearing карданного a shaft.
9. Ослабьте a tightening nut on карданном to a shaft.
10. Ослабьте, without unscrewing, bolts to the intermediate bearing карданного a shaft.
11. Unscrew карданный a shaft on a check point. Thus leave on карданном to a shaft a hinge disk.
12. Ослабьте unloading plugs in a flange of the hinge by means of a cylindrical core in diameter of 10 mm and length about 150 mm.
13. Squeeze out back карданный a shaft so as it allows the intermediate bearing and a tightening detail.
14. Separate the pipeline going to the distributive cylinder on a left-hand side шлангового of connection (arrow). Collect poured out brake liquid. Close joints stoppers.
15. Remove rods of plugs of a gear change from intermediate levers on an arm of the mechanism of a gear change, preliminary having wrung out safety скобы.
16. Unscrew bolts from a starter flange.
17. Unscrew all fixing bolts from a reducer on an intermediate flange. Thus three top bolts delete in last turn.
18. Unscrew a wire connecting the accumulator with weight of the car.
19. Turn to the left a transmission, remove horizontally back and Take it from муфты.
20. Lower a transmission.
The prevention

Transmission lower only when a primary shaft will take out cautiously from a coupling disk, the coupling disk differently can be damaged.


Installation

PERFORMANCE ORDER
1. Before installation check up муфту.
2. Check up ease of a course of the bearing муфты coupling deenergizings. Grease the bearing, for example, with greasing "Liqui Moly V-320". If before dismantling at coupling inclusion noise in bearing work муфты coupling deenergizings were audible, replace the bearing.
3. Clear and slightly grease молибденовой with paste or молибденовой распылительной greasing клиновой a gear wreath of a primary shaft, and also aligning pins.
The prevention

Gear wreath of a nave of a disk of coupling for a two-case flywheel отникелирован. Therefore at engines in volume of 2,2/2,8 l are not present necessity to grease a gear wreath of a primary shaft of a transmission.


4. Include the first transfer.
5. Raise, turn to the left and horizontally enter a transmission in муфту. If at introduction the primary shaft of a transmission is not fixed in a coupling disk, accordingly, manually turn a primary shaft behind in a flange for карданного a shaft.
6. Screw a transmission on an intermediate flange, thus screw at the left below on a check point a wire of weight of the storage battery.
The tightening moment:
Bolt of M 10 х 40 – 55 Н.м.
Bolt of M 10 х 45 – 55 Н.м.
Bolt of M 10 х 90 – 45 Н.м.
7. Hardly tighten a starter two bolts.  
8. Hang rods of plugs of a gear change on intermediate levers and fix their safety скобами. Thus compress spring clips, push a cut in a groove of a rod of a plug of a gear change and fix there.

The prevention

Use only safety скобы with закруглениями (marksman). At assemblage скобы should enter into gearing to guarantee a reliable support.


9. Attach the pipeline to the distributive cylinder.
10. As it is possible extend карданный a shaft from a sliding detail and прифланцуйте to a check point further. For this purpose raise the engine and a transmission by means of a garage jack and wooden linings a little.
11. Rigidly screw a back support of the engine with an arm on a check point.
12. Rigidly screw an arm of a support of the engine on a frame of the basis of a body.
13. Rigidly screw the intermediate bearing карданного a shaft.
14. Hardly tighten a tightening nut with the moment 35 Н.м.
15. Hardly screw the screen for the intermediate bearing карданного a shaft.
16. Mount system of release of the fulfilled gases, thus check up rubber rings on absence of porosity and damages.
17. Remove air from a drive of management of coupling.
18. Check up gear change installation.
19. Establish the bottom cover of a motor compartment.
20. Lower the car.
21. Take a sheet material from a motor compartment.
22. Connect to the plug of the storage battery a weight wire (–).
23. Establish time for hours.
24. Enter an anticreeping code of radio.

Adjustment

Gear change system

1-2. A rod of a plug of switching of the first and second transfer
3-4. A rod of a plug of switching of the third and fourth transfer
5-R. A rod of a plug of switching of the fifth transfer and backing transfer

PERFORMANCE ORDER
1. Establish a transmission in idling position (neutral position).
2. Remove safety скобы, then unhook rods of plugs of switching on intermediate levers.
1-2 = the intermediate lever for the first and second transfer;
3-4 = the intermediate lever for the third and fourth transfer;
5-R = the intermediate lever for the fifth transfer and backing transfer.
3. Enter a bolt-clamp () into apertures below on an arm of the mechanism of a gear change and by that fix three intermediate levers.
4. If it is required, make a bolt-clamp on the specified sizes.
5. Rods of plugs of a gear change should be squeezed out without pressure on a bolt with the intermediate lever. Otherwise ослабьте a counternut also establish the given guard of a plug of a gear change for the corresponding length. Hardly tighten a counternut.
6. Fix rods of plugs of a gear change (1) safety скобами.

The prevention

It is possible to use only safety скобы with закруглениями (marksman).


7. Take a bolt-clamp.
8. Check up functioning of system of a gear change at the working engine. Transfers should be established without jamming.
