Adjusting Locking Pawl

CAUTION: Before carrying out any adjustment or service work, always disengage all drives, shut off engine and wait until all moving parts have stopped.

If the slip clutch at length-of-cut transmission slips when changing over from reversing to forward, the reason may be an incorrect adjustment of the locking pawl.

With ignition off, remove locking pin (A). Rotate slip clutch forward by hand until it can be felt that the locking pawl is at the highest point of a cam on the cam wheel.
