Almond Drive Clutch Springs: The almond drive clutch spring (PN 7041566) MUST be installed with the tapered end to the spiderIf the spring in installed backwards, or the taper to clutch cover, premature wear will occur to clutch andor springCAUTION: Never shim drive clutch spring to increase its compression rateThis may result in complete stacking of the coils and subsequent clutch cover failureMaximum efficiency of the variable speed drive system is dependent upon many factorsIncluded in these are converter offset and alignment, belt tension, belt to sheave clearance, and condition of the drive and driven clutch componentsOne of the most critical and easily serviced parts is the drive clutch springDue to the severe stress the spring is subject to during operation, it should always be inspected and checked for tolerance limits during any clutch operation, diagnosis, or repairWith the spring resting on flat surface, measure free length from outer coil surfaces as shownRefer to the chart above for specific free length measurements and tolerancesIn addition to proper free length, the spring coils should be parallel to one another when placed on flat surfaceDistortion of the spring indicates stress fatigueReplacement is required999
