Righty tighty, lefty loosey.

If the crankshaft is turning have a friend put a breaker bar on the flywheel bolts to hold the crank in place.

impact wrench works to remove it but use a torque wrench and a friend for putting it back on.

You use that. If you don't have a air compressor I suggest you invest in one. I bought mine for $50 from Lowes (8 gallon)

As far as the harmonic balancer, you're suppose to use a special tool for that.



See?

I have no clue. The remover I used was designed differently. Mine grabs the pulley from the back and when you turn the bolt right it pulls the harmonic balancer to you causing it to come off.
