1Determine direction driven clutch needs to be adjusted(Refer to Clutch Offset Inspection procedure above)2Remove driven clutch retaining bolt, and remove driven clutch3Add or take out washers on jackshaft between the driven clutch and jackshaft bearing to achieve proper offset4Most models require the driven clutch to float on the jackshaftAfter adjusting offset, add or remove shim washers from the retaining bolt to provide .040-.100 (1-2.4mm) of float on jackshaftThis will prevent side loads on the jackshaft bearingNOTE: When checking electric start models, use straight edge as shown in Ill2If alignment is off, loosen the engine mounts and shift engine as required to obtain the proper offset and alignmentDriven Clutch Bolt Torque 12 ftlbs(16.6 Nm)
