DRIVE BELT DEFLECTION
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 belt guard2Make 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! NOTE: Push down on the belt with the ruler only until the bottom of the belt flexes upward; then read the amount of deflection

If premature drive belt wear is experienced or if the drive belt turns over, parallelismoffset must be checkedAlso, parallelismoffset must be checked whenever either the drive clutch or driven pulley is servicedTo check the offset, use the Clutch Alignment Bar (pn 0644-427) and to check parallelism, use the Clutch Alignment Bar (pn 0644-509) and the following proceduresCHECKING OFFSET
