“V” BELT ADJUSTMENT:
SDR-65
Begin by loosening 4 bolts at the base of the gearbox. Adjusting long
threaded bolt slides the gearbox back, tightening belt. After proper tension is
achieved, tighten 4 bolts at base of gearbox. You may have to place a ½” nut under
the head of the long threaded bolt to increase your adjustment length.
When changing belts, removal of grease fitting from the top of the center
spindle will make installation easier. Be sure belts run in proper groove.
