2. Install the bushing (021) on the caliper (1), lubricate the bushing (021) and sealing rings (12) and (13) with transmission oil, carefully install the piston (2) into the caliper (1), press in the piston (2) without tilting, turning it slightly.
3. Install the spring bushing (4) and springs (3).
4. Install the puller (020) on the spring sleeve (4) and install the retaining ring (5).
5. Install discs (6), (8) and (10) into the caliper (1).
6. Install the retaining ring (11).
Checking the gap
Check the gap "A". The nominal value of the gap "A" in the K2 clutch is within the range of 0.7-1.3 mm. Adjust the gap by selecting the retaining ring (11). Retaining rings are available in thicknesses of 2.0, 2.5 and 3.0 mm.
