Dismantling

Design of coupling of K3


44a — the External support 44b — the Sealing ring 44c — the Piston 44d — the Spring plate	44e, 44h — Lock rings 44f — the Disk spring 44g — the Block of disks 072 — the Stripper

PERFORMANCE ORDER

1. Remove a lock ring (44h) from an external support.
2. Remove the block of disks (44g) and a disk spring (44f) from an external support.
3. Establish a stripper (072) on a spring plate (44d) and press it until the lock ring (44e) is not released.
4. Remove a lock ring (44e).
5. Remove a spring plate (44d) and the piston (44c) from an external support.

Assembly

Check of a gap between a lock ring (44g) and an external disk (41a)


37 — Frictional disks thickness 1.6 mm thick/new is 2.1 mm 41a — the External disk 4.0 mm thick 41b — the External disk thickness 3.5 mm thick/new is 2.8 mm 41c — the External disk 1.8 mm thick	44a — the External support of coupling K3 44g — the Lock ring 44h — the Disk spring L — the Gap

Assembly is carried out as it should be, the return to dismantling. Check a gap between a lock ring (44g) and an external disk (41a). The size of gaps in coupling of K3 is specified below in the table. In case of need adjust a gap by selection of a lock ring (44g) of the required thickness. Rings 2.0, 2.3, 2.6, 2.9, 3.2 and 3.5 mm thick are issued.

The size of gaps in coupling of K3

Disk		Size of a gap, mm
3	2.30	2.70-3.10
4	2.40	3.00-3.40
5	2.50	3.30-3.70
