Dismantling and assembly 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, 84а. Gear wheel 84b, 104, 106 — Lock rings 85 — the Persistent needle bearing 100 — the Leading shaft with coupling К2 101 — the Piston 101 and — the Internal epiploon of the piston	101b — the External epiploon of the piston 102, 107 — Disk springs 103 — the Spring clamp 103а — the Epiploon of a spring clamp 105 — the Block of disks

Gap check between a lock ring 90 and an external disk 89с


100а — the External support of coupling К2 101 — the Piston 105а — 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 105с — the External disk in thickness of 4.0 mm	105d — Frictional disks 106 — the Lock ring 107 — the Disk spring «L» — the Gap

Dismantling

PERFORMANCE ORDER

1. Disconnect the transmission case from the hydrotransformer case.
2. Remove couplings К1, К2 and KZ.
3. Take a lock ring 84b from an internal support of coupling К1 84 and remove a gear wheel 84а.
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

PERFORMANCE ORDER

Assembly is carried out as it should be, the return to dismantling. Check a gap between a lock ring 106 and an external disk 105с.
The size of gaps in coupling К2 is specified in the table. Adjust a gap by means of a lock ring 106. Thickness of a lock ring: 2.3, 2.6, 2.9, 3.2, 3.5 and 3.8 mm.
