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 6c from an external support, carefully giving air to an opening And.


Assembly

 PERFORMANCE ORDER

1. Install the piston 6c 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 illustration, and establish them in turn.

6. Install a press 078 on an external drive 70c.

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 70c in three points. The size of gaps in a multidisk brake of B1 is specified in the table.

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.
