• Rotate the Cam Ring ‘B’, to release the Clutch, and
slide the Sprocket and Drum Assembly ‘C’, off the
Cam Shaft.
• Thoroughly clean the assembly with penetrating oil.
Do not use water or solvents.
• Inspect the inside of the Drum for scoring, and the
Clutch Rollers ’D’, for wear or damage.
NOTE
If a new Clutch Assembly is fitted, remove the Sprocket
and Taper Lock, from the worn Clutch, for re-use.
• Lubricate the assembly liberally with penetrating oil.
Do not use heavy oil or grease, these will cause
the clutch to slip.

• Ensure that the Clutch Cam Ring ‘B’, is ‘free’ and
it returns completely to the engaged position.
Spray liberally with penetrating oil.
• Fit the Drive Chain, set the chain tension allow ¼ to
