Drive Sprocket Height Adjustment Procedure

A spacer beneath the output sprocket is used to position the output sprocket in line with the transfer sprocket. The sprocket must be within 0.015" of each other. In order to do this operation, install original spacer over the output shaft. If original spacer is not available, use the thickest available shim as a starting point. Refer to Output Sprocket Spacer Chart for available sizes. Then install the two sprockets without the chain.

The chain sprockets are not reversible. Check the height difference using a straight edge (special tool 6311 or equivalent) and a set of feeler gauges.





If the output sprocket is lower than transfer sprocket, add the amount measured to the shim that was installed.

If the output sprocket is higher than transfer sprocket, subtract the amount measured to the shim that was installed.
