Removal


Prevention

Needlessly do not remove oil sealing rings.


PERFORMANCE ORDER
1. Remove the speedometer drive mechanism.
2. Passatizhami with long sponges, remove a hairpin.
3. After removal of the lever from a rod of the reverse gear, a passatizhama with long sponges remove the lever of switching of the reverse gear.
4. Weaken a bolt and remove the lever and a rod of switching.
5. Weaken two bolts and remove a partition and laying.

Prevention

If necessary, the screw-driver remove an external ring of the bearing of a secondary shaft.


6. Insert the screw-driver into an external ring of the bearing of a secondary shaft of a case of coupling.
7. Remove an external ring of the bearing.
8. When raising a bell and external ring of the bearing, remove an external ring of the bearing.
9. The screw-driver and the hammer remove a sealing ring of a rod of gear shifting.

Prevention

At removal of a sealing ring do not damage a coupling case.


10. The screw-driver remove a sealing ring of a main shaft.
11. The screw-driver remove a sealing ring of differential.
12. Establish a stripper of OK130 170 012 in an external ring of the bearing of differential.
13. Remove an external ring of the bearing of differential.
14. After installation of a stripper OK130 170 012 in an external ring of the bearing of differential, remove an external ring of the bearing and adjusting laying from a case nest.
15. The screw-driver remove a sealing ring of differential.

Prevention

Do not damage a transmission case.


16. The screw-driver and the hammer beat out an external ring of the bearing of a secondary shaft from a transmission case.

Installation


Prevention

Before installation of a case of coupling adjust a tightness of bearings selection and installation of adjusting laying:

      – tightness of a main shaft;
      – tightness of a secondary shaft;
      – differential tightness.

After measurement of preliminary loading use the picked-up laying as adjusting. Grease adjusting laying and external rings of bearings with oil for the transmission.


PERFORMANCE ORDER
1. After installation of adjusting laying in a transmission case nest, establish an external ring of the bearing of a secondary shaft.

Prevention

Oil an external surface of an oil sealing ring for the transmission.


2. Using a mandrel of OK201 170 AA1, establish an oil sealing ring of differential in a transmission case nest.
3. Using a mandrel of OK201 170 AA1, establish an oil sealing ring of differential in a coupling case nest.

Prevention

Establish adjusting laying which was selected at adjustment of a tightness of bearings of differential. Grease adjusting laying and external rings of bearings with oil for the transmission.


4. After installation of adjusting laying in a transmission case nest, establish an external ring of the bearing of differential.
5. Using a mandrel of OK201 170 AA1, establish an external ring of the bearing in a coupling case nest.

Prevention

Oil an external surface of an oil sealing ring of draft of gear shifting for the transmission.


6. Establish an oil sealing ring.

Prevention

Oil an external ring of the bearing of a secondary shaft for the transmission.


7. Establish a bell and an external ring of the bearing of a secondary shaft in a coupling case nest.

8. After installation of new laying, establish a plate and fix by bolts.

Inhaling moment: 6,8–10,7 N • m


Prevention

Establish a protective cover so that the opening for removal of air settled down from below.


9. Establish a cover on a gear shifting rod.
10. Install the lever and a rod of switching in a coupling case.
11. After installation of the lever and a rod of switching tighten a bolt.

Inhaling moment: 11,7–13,7 N • m

12. Install a shaft of the drive of a speedometer and a gear wheel on the plug.
3. Install a new sealing ring of round section on the speedometer plug.
14. Install the speedometer drive mechanism on a case of coupling and fix by a bolt.

Inhaling moment: 6,8-9,8 N of m
