Flywheel locks for Yamaha 701-760 motors.Â
Cold-Fusion has produced the safest way to remove engine couplers and flywheel bolts without risking damage to other engine components. Â Simple to use, it prevents crankshaft movement allowing you to remove other components without damage. Â Properly install your flywheel bolt to correct torque specs without resorting to the dangerous method of stuffing a rope down your cylinder. Â We have been able to use this tool while motors are still installed in skis, but your setup may differ.
