Harmonic Balancer Removal

yea you should use an impact with alot of grease or antisieze. You can do it without but find a way to keep the motor from turning. The bolt style is better than the claw style. if you have an air hammer someone hitting the old balancer with that while you try and turn it may help dont shake the motor too much though. As for installing you dont need an installer if the press is correct. Hit it on until it bottoms out. Make sure the crank is very clean with antisieze on the inside of the balancer and the crank snout with assembly lube on the part that rides on the seal.

If you mic your crank a local engine shop can tell you if the fit is correct if you bring your balancer to them. Also if it goes on hard you could heat it up alittle.
