Assembly
|
|
|
1. Install 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 about 80 mm long.
2. Establish basic laying (113) on a flange (79).
3. Insert the bearing of a brake B2 (29) with a finger (20) into the transmission case. Bigger diameter of a finger (28) has to be directed to a brake tape of a brake B2 (27).
4. Insert the plastic directing ring (88a) and a radial epiploon (88) into the transmission case. At installation, the sealing edge has to be directed to a cover of the piston (17) of a brake tape.
|
| 5. Check a persistent part of a brake of B2 (29) for a curvature. A persistent part, an opening and an ear (shooters), at removal, have to settle down water and same situation. |
|
| 6. Install a new sealing ring in the transmission case. Insert a persistent part of a brake of B2 (29) an ear up. |
|
| 7. Squeeze a brake tape of a brake B2 (27) as far as it is possible and insert it into the case, - the brake tape can be established by means of a lock ring for the B2 (23) piston. |
|
| 8. Grease grooves on an output shaft (167) and insert teflon rings (167a). |
|
| 9. Establish coupling of K2 (100) on planetary couple by means of the device (030). |
|
10. Insert planetary couple into the transmission case, turning the leading shaft (87).
11. Install the transmission by an expert shaft (87) vertically up. |
|
| 12. Check installation of planetary couple. Planetary couple is established correctly when the upper edge of a connecting support (shooter) is lower, than a basic surface (138) of an external multidisk brake of LB3. Establish a spring (134). The ledge (arrow A) on a spring has to be established inside. The damping spring has to be installed in a groove (arrow B) in the transmission case. |
|
13. Install the piston of a brake B2 (15), having pressed a cover of the piston of a brake of B2 (17) and having inserted a lock ring (23).
14. Establish and check a gap in a multidisk brake of LB3.
15. Establish coupling of K1 (83) on planetary couple (87). |
| 16. Establish the brake film B1 (30). |
|
17. Check a gap of a brake tape of a brake of B1 (see the Section Measurement of a Gap in B1 brake) - the nominal rate makes 1.8-2.4 mm.
18. Check a gap in a brake tape of a brake 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 check of a gap in a multidisk brake of B3) - nominal rate makes 1.5 - 2.0 mm.
20. Further assembly is carried out as it should be, the return to removal. |
