GENERAL INFORMATION

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 the coupling. As it is impossible to repair a transmission with application of handicraft house means, in it is necessary to address in a repair truck, only unit removal below is described.

Removal

PERFORMANCE ORDER

1. Disconnect from the plug of the storage battery a weight wire (–). Prevention The anticreeping code of radio is thus erased.
	2. Cover with a suitable sheet material a back wall of a motor compartment in order that when lowering a transmission not to damage isolating rug.
Prevention At cars with additional system of heating when lowering a transmission pay attention to that the hose with 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 laying.
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 (shooter).
	6. Unscrew an arm (1) support of the engine on the basis of a frame of a body (shooters).
7. Remove system of production of exhaust gases. Unscrew the holder (2) on a check point (shooter). In advance note the provision of a lining plate by compasses (describe a circle) that it was possible to establish it later again on a former place.
8. Unscrew the screen to the intermediate bearing of the driveshaft.
	9. Weaken a tightening nut on kardanny to a shaft.
10. Weaken, without unscrewing, bolts to the intermediate bearing of the driveshaft.
11. Unscrew the driveshaft on a check point. Thus leave on kardanny to a shaft a hinge disk.
	12. Weaken unloading plugs in a hinge flange by means of a cylindrical core in diameter of 10 mm and length about 150 mm.
13. Squeeze out back the driveshaft so as it allows the intermediate bearing and a tightening detail.
	14. Separate the pipeline going to the distributive cylinder on the left side of shlangovy connection (shooter). Collect the poured-out brake liquid. Close joints jams.
	15. Remove rods of forks of gear shifting from intermediate levers on an arm of the mechanism of gear shifting, previously having wrung out safety brackets.
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 the last turn.
	18. Unscrew a wire connecting the accumulator to mass of the car.
19. Turn to the left a transmission, remove horizontally back and Take it from the coupling.
20. Lower a transmission. Prevention Transmission lower only when primary shaft will take out carefully from a coupling disk, the coupling disk differently can be damaged.

Installation

PERFORMANCE ORDER

1. Before installation check the coupling.
2. Check ease of a course of the bearing of the coupling of switching off of coupling. Grease the bearing, for example, with Liqui Moly V-320 greasing. If before dismantling at inclusion of coupling noise in operation of the bearing of the coupling of switching off of coupling were audible, replace the bearing.
3. Clear and slightly grease with molybdenic paste or molybdenic raspylitelny greasing maple a gear wreath of primary shaft, and also aligning pins. Prevention Gear wreath of a nave of a disk of coupling for a two-case flywheel отникелирован. Therefore engines in volume of 2,2/2,8 l have no need to grease a gear wreath of primary shaft of a transmission.
4. Include the first transfer.
5. Raise, turn to the left and horizontally enter a transmission into the coupling. If at introduction primary shaft of a transmission is not fixed in a coupling disk, respectively, manually turn primary shaft behind in a flange for the driveshaft.
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. Tightening moment: Bolt of M of 10 x 40-55 N of m. Bolt of M of 10 x 45-55 N of m. Bolt of M of 10 x 90-45 N of m.
7. Hardly tighten a starter two bolts.
	8. Hang rods of forks of gear shifting on intermediate levers and fix them safety brackets. Thus compress spring clips, push a cut in a groove of a rod of a fork of gear shifting and fix there.
Prevention Use only safety brackets with curves (shooter). At assembly of a bracket should enter into gearing to guarantee a reliable support.
9. Attach the pipeline to the distributive cylinder.
10. As it is possible extend the driveshaft 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 laying 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 of the driveshaft.
14. Hardly tighten a tightening nut with the moment of 35 N of m.
15. Hardly screw the screen for the intermediate bearing of the driveshaft.
16. Mount system of production of exhaust gases, thus check rubber rings on lack of porosity and damages.
17. Remove air from a drive of management with coupling.
18. Check gear shifting 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 on hours.
24. Enter an anticreeping code of radio.

Adjustment

Gear shifting system


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

PERFORMANCE ORDER

1. Establish a transmission in the provision of idling (neutral situation).
	2. Remove safety brackets, then unhook rods of forks 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 (And) into openings below on an arm of the mechanism of gear shifting and by that fix three intermediate levers.
	4. If it is required, make a bolt clamp on the specified sizes.
	5. Rods of forks of gear shifting should be squeezed out without tension on a bolt with the intermediate lever. Otherwise weaken a lock-nut and establish this guard of a fork of gear shifting for the corresponding length. Hardly tighten a lock-nut.
	6. Fix rods of forks of gear shifting (1) safety brackets.
Prevention It is possible to use only safety brackets with curves (shooter).
7. Take a bolt clamp.
8. Check functioning of system of gear shifting at the working engine. Transfers should be established without jamming.
