Re: harmonic balancer puller
Where people go wrong pulling a harmonic balancer, on cars or boats, is they use a gear pull which pulls from the outside edges of the balancer. Problem is, the balancer is rubber cast around a metal center and using a gear pull can separate the two ruining the balancer.
Anything that will screw into the metal portion of the balancer then push on the crankshaft to press the balancer off the crank will work fine for automotive or boats provided you have enough room in the engine compartment to get that tool in front of the motor.
