Dismantling and assembly 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
42а — the Needle bearing
42b — Teflon rings
42с, 43а — Persistent laying
42d — the Persistent needle bearing
42е — Laying

42f — the Lock ring
43 — the Back block of planetary gear wheels
44 — KZ Coupling
45 — the Back hollow shaft
With — the Final oil channel for KZ coupling
D — the Inlet oil channel for KZ coupling


Gap check between laying 42е and a lock ring 42f

42 — the Target shaft
42с — Persistent laying
42d — the Needle bearing

42е — Laying
42f — the Lock ring
44 — KZ Coupling


Dismantling

 PERFORMANCE ORDER

1. Disconnect the transmission case from the case the hydrotransformer.
2. Remove multidisk couplings К1, К2 and KZ.
3. Remove up two visible teflon rings 42b from a target shaft.
4. Remove a lock ring 42f, laying 42е, the persistent needle bearing 42d and persistent laying 42с from a target shaft.
5. Remove KZ 44 coupling.
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 persistent laying 43а.
9. Remove multidisk brake В1 and the oil pump.


Assembly

 PERFORMANCE ORDER

1. Establish persistent laying 43а 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 KZ couplings.
6. Establish a lock ring, laying, the persistent needle bearing and persistent laying.
7. Grease and establish two top teflon rings 42b in a groove so that they were established together.
8. Check an axial gap between laying 42е and a lock ring 42f. It should make 0.15 - 0.6 mm. Adjust a gap by means of laying 42е. Thickness of laying: 3.0, 3.4 and 3.7 mm.
9. Establish multidisk couplings К1, К2 and KZ.
