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.
