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 start-
ing point. Refer to Output Sprocket Spacer Chart for
available sizes. Then install the two sprockets with-
out the chain.
