Dismantling and assembly of a back hollow shaft with the back coupling of a free wheeling

Dismantling and assembly of a back hollow shaft with the back coupling of a free wheeling


45a — the Hollow shaft 45b — the Sealing ring 45s — the Lock ring 45d — the Coupling of a free wheeling 45e — the Back solar gear wheel with an internal support of coupling K3	45f — the Persistent needle bearing 45g — Laying 45h — the Blocking ring

Dismantling

PERFORMANCE ORDER

1. Disconnect the transmission case from the case the hydrotransformer.
2. Remove multidisk couplings of K1, K2 and K3.
3. Remove a blocking ring (45h), laying (45g) and the persistent needle bearing (45f) from a hollow shaft (45a).
4. Remove a back solar gear wheel (45e) together with an internal support of coupling K3 and the back coupling of a free wheeling (45d).
5. Remove a lock ring (45s) from the coupling of a free wheeling (45d).
6. Remove the coupling of a free wheeling from a solar gear wheel.

Assembly

PERFORMANCE ORDER

Assembly is carried out as it should be, the return to dismantling. Check correctness of installation of lock rings. Check them and if it is necessary, replace them. Persistent laying of the coupling of a free wheeling (45d) has to settle down in the direction to a lock ring (45s).
