Dismantling

 PERFORMANCE ORDER

1. Remove a lock ring (6h).
2. Remove the block of disks (6g) and a disk spring (6f) from an external support
3. Establish a stripper (073) on a disk spring (6d) and compress it until the groove for a lock ring will not be released.
4. Remove a lock ring (6е).
5. Remove the piston (6с) from an external support, carefully submitting air to an opening And.


Assembly

 PERFORMANCE ORDER

1. Establish the piston (6с) on an external support.
2. Establish a disk spring (6d).
3. Establish a stripper (073) on a disk spring (6d) and compress it until the lock ring (6е) will not be established in a groove.
4. Insert a lock ring (6е).
5. Insert a disk spring (6f) and the block of disks (6g) on an external support and measure a gap of L. Insert disks of brake В1 together in an order presented on an accompanying illustration, and establish them in turn.

6. Establish a press (078) on an external disk (70с).

7. Compress the block of disks against the stop (while the otmetochny ring will not be visible) (a small arrow).
8. Measure a gap of "L" between a lock ring (6h) and an external disk (70с) in three points. The size of gaps in multidisk brake В1 is specified in table 1.
9. Adjust a gap a lock ring (6h) if it is necessary.
Thickness of a lock ring: 2.6, 2.9, 3.2, 3.5, 3.8 and 4.1 mm.
10. Establish a lock ring (6h).
