Dismantling

PERFORMANCE ORDER

1. Disconnect the transmission case from the hydrotransformer case.
2. Remove couplings of K1, K2 and K3.
3. Take a lock ring (84b) from an internal support of coupling K1 (84) and remove a gear wheel (84a).
4. Remove the conducting shaft with coupling of K2 (100).
5. Remove the needle persistent bearing (85).
6. Remove a lock ring (106) from an external support of coupling K2.
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) is not released.

10. Remove a lock ring (104).
11. Remove a disk spring (102) and take the piston (101) from 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 (105s).

The size of gaps in coupling of K2 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.
