What happens if the harmonic balancer bolt is loose?
One type of damage that can happen if the harmonic balancer bolt is loose is that the HB hub wears and the key and keyways in the HB hub and crankshaft nose wallow out. So the HB and crankshaft should be inspected to see if there is damage to the key and keyways as well as fit of the HB hub to the crankshaft nose.

What’s the best way to loosen nuts and bolts?
