Dismantling

Dismantling and assembly of coupling of K1

83a — the External support of coupling K1
83b — the Sealing ring
86 — the Piston
86a — the Sealing ring of the piston
86b — the Disk spring
87 — the Spring plate

87a — the Sealing ring of a spring plate
88, 90 — Lock rings
89 — the Block of disks
91 — the Lock ring of the coupling of a free wheeling
92 — the Forward coupling of a free wheeling
A — the Oil channel for coupling of K1


 PERFORMANCE ORDER

1. Remove a lock ring (90) from an external support.
2. Remove the block of disks (89) from an external support.
3. Establish a stripper (072) on a spring plate (87) and squeeze it until the lock ring (88) is not released.
4. Remove a disk spring (86b) and the piston (86), having given compressed air to an opening (A).

Assembly

Check of a gap between a lock ring (90) and an external disk (89c)

83a — the External support of coupling K1
86 — the Piston
86b — the Disk spring
89a — the External disk (thickness of 1.8 mm)
89b — the External disk (thickness of 3.5 mm / new thickness is 2.8 mm)

89c — the External disk (thickness of 4.0 mm)
89d — Frictional disks
90 — the Lock ring
L — the Gap


Assembly is carried out as it should be, the return to dismantling. Check a gap between a lock ring (90) and an external disk (89c). The size of gaps in coupling of K1 is specified below in the table. In case of need adjust a gap by selection of a lock ring (90) of the required thickness. Rings 2.6, 2.9, 3.2, 3.5, 3.8 and 4.1 mm thick are issued.
