Dismantling and assembly of an output shaft with the central and back block of planetary gear wheels

42 — the Output shaft with the central block of planetary gear wheels
42a — the Needle bearing
42b — Teflon rings
42s, 43a — Persistent laying
42d — the Persistent needle bearing
42e — Laying
42f — the Lock ring
43 — the Back block of planetary gear wheels
44 — Coupling of K3
45 — the Back hollow shaft
With — the Final oil channel for coupling of K3
D — the Inlet oil channel for coupling of K3

Check of a gap between laying 42e and a lock ring 42f

42 — the Output shaft
42s — Persistent laying
42d — the Needle bearing
42e — Laying
42f — the Lock ring
44 — Coupling of K3

Dismantling

 PERFORMANCE ORDER

1. Disconnect the transmission case from the hydrotransformer case.
2. Remove multidisk couplings of K1, K2 and K3.
3. Remove two visible teflon rings (42b) from an output shaft up.
4. Remove a lock ring (42f), laying (42e), the persistent needle bearing (42d) and persistent laying (42s) from an output shaft.
5. Remove coupling of K3 (44).
6. Remove a back hollow shaft (45) from an output shaft.
7. Remove the back block of planetary gear wheels (43) with the built-in hollow shaft, the central block of planetary gear wheels from an output shaft.
8. Remove persistent laying (43a).
9. Remove a multidisk brake of B1 and the oil pump.


Assembly

 PERFORMANCE ORDER

1. Establish persistent laying (43a) by a cuff towards a vodil.
2. Install the back block of planetary gear wheels (43) with the built-in hollow shaft, the central block of planetary gear wheels on an output shaft.
3. Grease and establish three lower teflon rings (42b) in a groove so that they were established together.
4. Establish a back hollow shaft (45) on an output shaft. Check sealing rings on a hollow shaft and replace them if it is necessary.
5. Establish couplings of K3.
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 (42e) and a lock ring (42f). It has to 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.
9. Establish multidisk couplings of K1, K2 and K3.
