8.18. Dismantling and assembly of coupling of K3

44a — the External support
44b — the Sealing ring
44s — the Piston
44d — the Spring plate

44e, 44h — Lock rings
44f — the Disk spring
44g — the Block of disks
072 — the Stripper

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

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
41s — the External disk 1.8 mm thick

44a — the External support of coupling of KZ
44g — the Lock ring
44h — the Disk spring
L — the Gap



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 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 KZ is specified in table 5. Adjust a gap by means of a lock ring 44g. Thickness of a lock ring: 2.0, 2.3, 2.6, 2.9, 3.2 and 3.5 mm.
