Dismantling

 PERFORMANCE ORDER

1. Remove a lock ring 44h from an external support.
2. Remove the block of disks 44g and a disk spring 44f from an external support.
3. Establish a stripper 072 on a spring plate 44d and press it until the lock ring 44е will not be released.
4. Remove a lock ring 44е.
5. Remove a spring plate 44d and the piston 44с 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 44g and an external disk 41а.

The size of gaps in coupling of KZ is specified in table 5. Adjust a gap by means of a lock ring 44g. Thickness of a lock ring: 2.0, 2.3, 2.6, 2.9, 3.2 and 3.5 mm.
