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