Dismantling and assembly of the coupling of a free wheeling

Design of the coupling of a free wheeling

1 — Koronchataya a gear wheel
2, 4 — Lock rings
3 — Laying

5 — the Sealing ring
6 — the Roller bearing
9 — the Internal ring of the coupling
10 — the External ring of the coupling


1. Disassemble a transmission (see. Section Dismantling and transmission assembly).
2. Remove a lock ring (2).
3. Remove the coupling (assembled), without assorting it, from a koronchaty gear wheel (1).
4. Remove a lock ring (4).
5. Remove laying (3).
6. Remove a sealing ring (5).
7. Remove an internal ring (9) couplings from the roller bearing (6).
8. Remove the roller bearing (6).
9. Check an external ring (10) couplings, the roller bearing (6) and an internal ring (9) couplings on lack of wear.
10. Check an axial gap of the coupling. It should be within 0.05 - 0.2 mm.
11. Establish laying (11) so that the neck (arrow) on an external ring of the coupling was established in an opening.
12. Establish laying (17) and an external ring of the 10th coupling with an internal ring (9) in a connecting support.
13. Establish a persistent washer (18) in an internal disk (24).
14. Establish an internal disk (24) in a connecting support (7). Establish a lock ring (21).
15. Check an axial gap between laying (17) and a connecting support (7), the axial gap is regulated by selection of laying. Laying in thickness 0.1, 0.2 and 0.3 mm are issued.
