Dismantling and assembly of a target shaft with central and back blocks of planetary gear wheels

Dismantling

Details of installation of components of a target shaft with the central and back block of planetary gear wheels


42 — the Target shaft with the central block of planetary gear wheels 42a — the Needle bearing 42b — Teflon rings 42c, 43a — the Persistent washer 42d — the Persistent needle bearing 42e — Laying	42f — the Lock ring 43 — the Back block of planetary gear wheels 44 — Coupling К3 45 — the Back hollow shaft With — the Final oil channel for coupling К3 D — the Inlet oil channel for coupling К3

PERFORMANCE ORDER

1. Disconnect the transmission case from the case the hydrotransformer.
2. Remove multidisk couplings К1, К2 and К3.
3. Remove up two visible teflon rings (42b) from a target shaft.
4. Remove a lock ring (42f), laying (42e), the persistent needle bearing (42d) and a persistent washer (42c) from a target shaft.
5. Remove coupling К3 (44).
6. Remove a back hollow shaft (45) from a target shaft.
7. Remove the back block of planetary gear wheels (43) with the integrated hollow shaft, the central block of planetary gear wheels from a target shaft.
8. Remove a persistent washer (43a).
9. Remove multidisk brake В1 and the oil pump.

Assembly

PERFORMANCE ORDER

1. Establish a persistent washer (43a) a cuff in the direction to водилу.
2. Establish the back block of planetary gear wheels (43) with the integrated hollow shaft, the central block of planetary gear wheels on a target shaft.
3. Grease and establish three bottom teflon rings (42b) in a groove so that they were established together.
4. Establish a back hollow shaft (45) on a target shaft. Check sealing rings on a hollow shaft and replace them if it is necessary.
5. Establish couplings К3.
6. Establish a lock ring, laying, the persistent needle bearing and a persistent washer.
7. Grease and establish two top teflon rings (42b) in a groove so that they were established together.

Gap check between laying (42e) and a lock ring (42f)


42 — the Target shaft 42c — the Persistent washer 42d — the Needle bearing	42e — Laying 42f — the Lock ring 44 — Coupling К3

PERFORMANCE ORDER

1. Check an axial gap between laying (42e) and a lock ring (42f). It should make 0.15 - 0.6 mm. Adjust a gap by means of laying (42e). Thickness of laying 3.0, 3.4 and 3.7 mm.
2. Establish multidisk couplings К1, К2 and К3.
