PERFORMANCE ORDER
1) install the transmission at the repair stand
2) merge gearbox oil
3) remove the lever of switching off of coupling and the release bearing of coupling
4) remove the directing plug
5) remove the lock ring established in front of the ball-bearing and measure its thickness
6) remove the ball-bearing from a transmission case by means of a stripper
7) remove the lock ring established behind the ball-bearing and measure its thickness
8) remove bolts between a transmission case / cover (for differential) and uncover together with differential
9) remove bolts between a case of coupling and a case of the transmission and remove a transmission case
10) remove the multi-function sending device
11) remove switching shaft bolts

12) remove a bolt of the lock and get the lock

13) remove together the leading shaft, the leading gear wheel, a switching shaft, rods of switching and a fork of switching
14) assembly is carried out upside-down to dismantling, at the same time pay attention to the following:
      – the leading shaft, the leading gear wheel, a switching shaft, rods of switching and a fork of switching are established together;
      – lock rings for the ball-bearing on the leader to a shaft have to be established on the old place and to be the same thickness

Prevention

Before installation of a case of the transmission, check that the directing plugs were installed in a transmission case.

Handle the sending device of a speedometer very accurately. Do not drop it, otherwise indications of a speedometer can be not exact.

If you need to replace a case of the main transfer or a conic roller bearing of the leading gear wheel or a hollow shaft and the deviation of r is not designated on a conic cogwheel, the provision of installation of the leading gear wheel should be defined before removal of a case of the transmission (it is necessary to take measurements of the valid size of a deviation).

if you are going to use the old ball-bearing and a shaft, it is necessary to measure thickness of an old lock ring and to replace it new the same thickness

Lock rings differ on thickness and diameter and they should be measured at removal. When replacing a gear wheel or shaft the corresponding lock rings should be measured for installation of a ring of the required thickness and diameter.

Rings of synchronizers and nave of the synchronizer, replacement

Since 26.01.87 of a ring of synchronizers began to be issued with a new external diameter and the flute on a nave of the synchronizer was reduced by 0.6 mm. Do not establish together a nave of the sliding couplings and a ring of synchronizers of the different sizes.

When replacing conic roller bearings define the provision of their installation before removal of the leading gear wheel and hollow shaft.

Do not damage edge of an epiploon between conic roller bearings.
