Assembly
|
|
|
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).
4. Insert a plastic directing ring (88a) and a radial epiploon (88) into the transmission case. At installation, the sealing edge should be directed to a cover of the piston (17) of a brake tape.
|
| 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. |
