Assembly
Checking the clearance between the retaining ring (90) and the outer disc (89c)
83a - Outer clutch support K1; 86 - Piston; 86b - Disc spring; 89a - Outer disk (1.8 mm thick); 89b - Outer disk (thickness 3.5 mm/new thickness 2.8 mm); 89c - Outer disk (4.0 mm thick); 89d - Friction discs; 90 - Retaining ring; L - Gap
Assembly is carried out in the reverse order of disassembly. Check the gap between the retaining ring (90) and the outer disk (89c). The gap size in the K1 clutch is given in the table below. If necessary, adjust the gap by selecting a retaining ring (90) of the required thickness. Rings with a thickness of 2.6, 2.9, 3.2, 3.5, 3.8 and 4.1 mm are produced.
