Dismantling

 PERFORMANCE ORDER

1. Disconnect the transmission case from the hydrotransformer case.
2. Remove couplings К1, К2 and KZ.
3. Take a lock ring 84b from an internal support of coupling К1 84 and remove a gear wheel 84а.
4. Remove a leading shaft with coupling К2 100.
5. Remove the needle persistent bearing 85.
6. Remove a lock ring 106 from an external support of coupling К2.
7. Remove the block of disks 105.
8. Remove a disk spring 107.

9. Establish a stripper 076 on a spring clamp 103 and press on it until the lock ring 104 will not be released.

10. Remove a lock ring 104.
11. Remove a disk spring 102 and take the piston 101 of an external support.


Assembly

 PERFORMANCE ORDER

Assembly is carried out as it should be, the return to dismantling. Check a gap between a lock ring 106 and an external disk 105с.
The size of gaps in coupling К2 is specified in the table. Adjust a gap by means of a lock ring 106. Thickness of a lock ring: 2.3, 2.6, 2.9, 3.2, 3.5 and 3.8 mm.
