Assembly

 PERFORMANCE ORDER

1. Establish a flange (79) with a sealing ring (197) and teflon rings (115) in the transmission case. Before installation of a flange (79), be convinced that the greasing constrictor is established in a flange (79), - for installation of a flange (79) use two bolts in length about 80 mm.
2. Establish basic laying (113) on a flange (79).
3. Insert the bearing of brake В2 (29) with a finger (20) into the transmission case. Bigger diameter of a finger (28) should be directed to a brake tape of brake В2 (27).

5. Check a persistent part of brake В2 (29) on a curvature. The persistent part, an opening and an ear (shooters), at removal, should settle down water and same situation.
6. Establish a new sealing ring in the transmission case. Insert a persistent part of a brake of B2 (29) an ear up.
7. Compress a brake tape of brake В2 (27) as far as it probably and insert it into the case, - the brake tape can be established by means of a lock ring for the B2 piston (23).
8. Grease grooves on a target shaft (167) and insert teflon rings (167a).
9. Establish coupling К2 (100) on planetary pair by means of the device (030).
10. Insert planetary pair into the transmission case, turning a leading shaft (87).
11. Establish a transmission expert shaft (87) vertically up.
12. Check installation of planetary pair. The planetary pair is established correctly when the upper edge of a connecting support (shooter) is lower, than a basic surface (138) external multidisk brakes of LB3. Establish a spring (134). The ledge (arrow A) on a spring should be established inside. The Dempferny spring should be established in a groove (arrow B) in the transmission case.
13. Establish the piston of brake В2 (15), having pressed a cover of the piston of brake В2 (17) and having inserted a lock ring (23).
14. Establish and check a gap in a multidisk brake of LB3.
15. Establish coupling К1 (83) on planetary to steam (87).
16. Establish the brake tape B1 (30).
17. Check a gap of a brake tape of brake В1 (see. The section gap Measurement in brake В1) - nominal rate makes 1.8-2.4 mm.
18. Check a gap in a brake tape of a brake of B2, - the nominal rate makes 5.5-6.0 mm.
19. Check a gap in a multidisk brake of B3 (see. The section Installation and gap check in multidisk brake В3) - nominal rate makes 1.5 - 2.0 mm.
20. Further assembly is carried out as it should be, the return to removal.
