Dismantling

PERFORMANCE ORDER

1. Remove a lock ring 134a.
2. Remove the block of disks of a brake B2 134 and a disk spring 134b from an external support of a brake B2.
3. Establish a stripper 074 on a disk spring 29 and squeeze it until the groove for a lock ring is not released.
4. Remove a lock ring 31.
5. Remove a spring plate 30 and a disk spring 29.
6. Disconnect the directing ring of the 28th piston and the piston of a brake B2 27 from the B3 piston 14a, having given compressed air to an opening of D.
7. Press the directing ring 28 from the B2 27 piston.
8. Remove a guide 32 from the B3 piston 14a, having given compressed air to an opening And.

Assembly

PERFORMANCE ORDER

1. Establish a guide 32 and the VZ 14a piston in the correct situation. For this purpose, insert a guide 32 into the case of transmission 2 and tighten. Press an external support of a brake B2 14a against the stop in a guide 32. Bore on vents or a cut on an external support of a brake B2 14a have to be directed (arrow) down.
2. Insert the piston of a brake B2 27 into VZ 14a brake piston. The rounded-off ends of sealing rings 14s, 28a and 28b have to be directed outside. The rounded-off end of a sealing ring 14d has to be directed in inside.
3. Insert the directing ring of the 28th piston. The valve 137 in the directing ring of the piston has to 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 squeeze it until the groove for a lock ring is not released.
6. Insert a lock ring 31.
7. Insert a disk spring 134b and the block of disks 134 on an external support of a brake B2.
8. Establish VZ brake disks together in the order presented on an illustration 109 and insert them in turn.
9. Install a press 078 on an external drive 70c.
10. Squeeze the block of disks by means of a press against the stop until the otmetochny ring is visible (a small arrow).
11. Measure a gap of L in three points between a lock ring 144a and an external disk 134a. The size of gaps in a multidisk brake 82 are provided in the table.

12. Adjust a gap a lock ring 144a 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.
