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 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 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.
10. Establish a lock ring 6h.
