Assembly
Checking the clearance between the retaining ring (90) and the outer disc (89c)
100a - Outer support of clutch K2; 101 - Piston; 105a - Outer disc thickness 1.8 mm; 105b - Outer disc thickness 3.5 mm/new thickness 2.8 mm; 105c - Outer disc thickness 4.0 mm; 105d - Friction discs; 106 - Retaining ring; 107 - Disc spring; L - Gap
Assembly is carried out in the reverse order of disassembly. Check the gap between the retaining ring (106) and the outer disk (105c). The gap size in the K2 clutch is given in the table below. If necessary, adjust the gap by selecting a retaining ring (106) of the required thickness. Rings with a thickness of 2.3, 2.6, 2.9, 3.2, 3.5 and 3.8 mm are produced.
