Dismantling

 PERFORMANCE ORDER

1. Remove a lock ring (90) from an external support (address an accompanying illustration).
2. Remove the block of disks (89) from an external support.

3. Establish a stripper (072) on a spring plate (87) and squeeze it until the lock ring (88) is not released.

4. Remove a disk spring (86b) and the piston (86), having given to an opening And compressed air.


Assembly

 PERFORMANCE ORDER

Assembly is carried out as it should be, the return to dismantling. Check a gap between a lock ring (90) and an external disk (89s). Adjust a gap by means of a lock ring (90). Thickness of a lock ring: 2.6, 2.9, 3.2, 3.5, 3.8 and 4.1 mm.
