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

Dismantling

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


45a — the Hollow shaft 45b — the Sealing ring 45c — the Lock ring 45d — the Coupling of a free wheeling	45e — the Back solar gear wheel with an internal support of coupling К3 45f — the Persistent needle bearing 45g — Laying 45h — the Blocking ring

PERFORMANCE ORDER

1. Disconnect the transmission case from the case the hydrotransformer.
2. Remove multidisk couplings К1, К2 and К3.
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 К3 and the back coupling of a free wheeling (45d).
5. Remove a lock ring (45c) from the coupling of a free wheeling (45d).
6. Remove the coupling of a free wheeling from a solar gear wheel.

Assembly

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. The persistent washer of the coupling of a free wheeling (45d) should settle down in the direction to a lock ring (45c).
