Dismantling and assembly of a leading shaft with coupling К2 and the forward block of planetary gear wheels

Dismantling

Details of installation of components of a leading shaft with coupling К2 and the forward block of planetary gear wheels

84 — the Internal support of coupling К1 with the integrated forward block of planetary gear wheels
84a — the Gear wheel
84b, 104, 106 — Lock rings
85 — the Persistent needle bearing
100 — the Leading shaft with coupling К2
101 — the Piston

101a — the Internal epiploon of the piston 101b — the External epiploon of the piston
102, 107 — Disk springs
103 — the Spring clamp
103a — the Epiploon of a spring clamp
105 — the Block of disks


 PERFORMANCE ORDER

1. Disconnect the transmission case from the case the hydrotransformer.
2. Remove couplings К1, К2 and К3.
3. Take a lock ring (84b) from an internal support of coupling К1 (84) and remove a gear wheel (84a) (see сопр. illustration).
4. Remove a leading shaft with coupling К2 (100).
5. Remove the needle persistent bearing (85).
6. Remove a lock ring (106) from an external support of coupling К2.
7. Remove the block of disks (105).
8. Remove a disk spring (107).
9. Establish a stripper (076) on a spring clamp (103) and press on it until the lock ring (104) will not be released.
10. Remove a lock ring (104).
11. Remove a disk spring (102) and take the piston (101) of an external support.

Assembly

Gap check between a lock ring (90) and an external disk (89c)




100a — the External support of coupling К2
101 — the Piston
105a — the External disk in thickness of 1.8 mm
105b — the External disk in thickness of 3.5 mm / new thickness of 2.8 mm
105c — the External disk in thickness of 4.0 mm

105d — Frictional disks
106 — the Lock ring
107 — the Disk spring
L — the Gap


Assembly is carried out as it should be, the return to dismantling. Check a gap between a lock ring (106) and an external disk (105c). The size of gaps in coupling К2 is specified below in the table. In case of need adjust a gap by selection of a lock ring (106) demanded thickness. Rings in thickness 2.3, 2.6, 2.9, 3.2, 3.5 and 3.8 mm are issued.
