Dismantling

 PERFORMANCE ORDER

1. Remove a lock ring (90) from an external support (address to 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 compress it until the lock ring (88) will not be released.

4. Remove a disk spring (86b) and the piston (86), having submitted to an opening And the 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 (89с). 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.
