NOTE:
. Clean all parts thoroughly in solvent or carburetor
cleaner, and dry them with compressed air.
. Blow out all passages.
. Lubricate all parts with CW Fluid before reassembly.
1. Inspect the check valve; if it's loose, replace the pis-
ton.

3. Install the piston in the clutch drum. Apply pressure
and rotate to ensure proper seatang,
NOTE: Lubricate the piston O-ring with CVT Fluid
before installing.
CAUTION: Do not pinch thc O-ring by installing the
pistoo with too much torqo.

Check the inner wall of the valve housing where theseal ring slides with your finger. lf there is a step inthe wall, the valve housing is worn. Replace thevalve housing.
NOTE:
There may be the sliding marks from the sealring on the wall of the valve housing. Replace
the valve housing only if the wall is stepped.When the valve housing is replaced, jnstall new
shim(s) on the bearing surface of the housing toadjust the thickness.
Check the inside of valve housingwhether the wall is stepped.
