Dismantling

 PERFORMANCE ORDER

1. Remove a lock ring 134а.
2. Remove the block of disks of a brake В2 134 and a disk spring 134b from an external support of brake В2.
3. Establish a stripper 074 on a disk spring 29 and compress it until the groove for a lock ring will not be released.
4. Remove a lock ring 31.
5. Remove a spring plate 30 and a disk spring 29.
6. Disconnect directing ring of the 28th piston and the piston of a brake В2 27 from the B3 piston 14а, having submitted the compressed air to an opening of D.
7. Press directing ring 28 from the piston В2 27.
8. Remove directing 32 from the B3 piston 14а, having submitted the compressed air to an opening And.


Assembly

 PERFORMANCE ORDER

1. Establish directing 32 and the VZ 14а piston in the correct situation. For this purpose, insert directing 32 into the case of transmission 2 and tighten. Press an external support of brake В2 14а against the stop in directing 32. Bore on shlitsa or cut on an external support of brake В2 14а should be directed down (arrow).
2. Insert the piston of a brake В2 27 into the piston of a brake of VZ 14а. The rounded-off ends of sealing rings 14с, 28а and 28b should be directed outside. The rounded-off end of a sealing ring 14d should be directed in inside.
3. Insert directing ring of the 28th piston. The valve 137 in a directing ring of the piston should be from above.
4. Insert a disk spring 29 and a spring plate 30.
5. Establish a stripper 074 on a disk spring 29 and compress it until the groove for a lock ring will not be released.
6. Insert a lock ring 31.
7. Insert a disk spring 134b and the block of disks 134 on an external support of brake В2.
8. Establish disks of a brake of VZ together in an order presented on an illustration 109 and insert them in turn.
9. Establish a press 078 on an external disk 70с.
10. Compress the block of disks by means of a press against the stop while the otmetochny ring will not be visible (a small arrow).
11. Measure a gap of L in three points between a lock ring 144а and an external disk 134а. Size of gaps in a multidisk brake 82 are provided in the table.

12. Adjust a gap a lock ring 144а if it is necessary. Thickness of a lock ring: 2.9, 3.2, 3.5, 3.8 and 4.1 mm.
13. Establish a lock ring 134a.
