CORRECTING OFFSET
DRIVE BELT DEFLECTION
1To correct offset, the driven pulley must be moved laterally on the output shaftRemove the cap screw and washers securing the driven pulley; then remove the driven pulley! NOTE: If the driven pulley is tight on the input shaft, pull the driven pulley off using the Driven Pulley Puller (pn 0644-469)
Drive belt length, condition, and deflection are all important for peak performanceTo check and adjust drive belt deflection, use the following procedure1Turn the engine off; then open the access panel2Make sure the drive belt is sitting at the top of the driven pulley sheaves3Place straightedge on top of the drive beltThe straightedge should reach from the drive clutch to the top of the driven pulley4Using stiff ruler centered between the drive clutch and driven pulley, push down on the drive belt just enough to remove all slackNote the amount of deflection on the ruler at the bottom of the straightedgeThe deflection should be at 31 mm (1 14 in
2To move the driven pulley inward on the shaft, remove washer(s) as required from behind the pulley3To move the driven pulley outward on the shaft, add alignment washer(s) as required behind the driven pulley
