Start by rotating the drive belt tensioner to the clockwise direction which will loosen the V-belt before removing both pieces of equipment and gradually readjusting the tensioner position. A jack with wooden spacer beneath the engine allows removal of the right-hand side engine mounting insulator sub-assembly by disassembling five bolts and two nuts.
