Engine Harmonic balancer wobble problem (Chevy 283 crate engine)
john’s question:
Harmonic balancer wobbles a little on my 283 chevy engine. It is a 62-63 year model. Engine runs fine with the exception of the wobble
Answer:
The balancer is either bent, OR the keyway is breaking down on the crankshaft. I’d advise taking the fan belts off, and removing the balancer. Then check to make sure the keyway isn’t damaged (if it is, then fix it with a new key NOW before it breaks off and ruins the crank.) If the keyway is fine, then just replace the pulley with a non worn one.
