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 squeeze it until the groove for a lock ring is not released.
4. Remove a lock ring (6e).
5. Remove the piston (6s) from an external support, carefully giving air to an opening And.


Assembly

 PERFORMANCE ORDER

1. Install the piston (6s) on an external support.
2. Establish a disk spring (6d).
3. Establish a stripper (073) on a disk spring (6d) and squeeze it until the lock ring (6e) is not established in a groove.
4. Insert a lock ring (6e).
5. Insert a disk spring (6f) and the block of disks (6g) on an external support and measure a gap of L. Insert B1 brake disks together in the order presented on an accompanying illustration, and establish them in turn.

6. Install a press (078) on an external drive (70s).

7. Squeeze the block of disks against the stop (still otmetochny ring will not be visible) (a small arrow).
8. Measure a gap of "L" between a lock ring (6h) and an external disk (70s) in three points. The size of gaps in a multidisk brake of B1 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).
