Balancer install

Luch · 11-05-2009, 02:07 AM

I understand the puller for removal on the harmonic balancer or power steering pump pulley...as far as assembly; do these usually push on easily or what is the proper process to re-install? I fugured maybe tap with a brass hammer in the center or a piece of wood and tap on that?

Align the keyway slot on the harmonic balancer onto the keyway on the crankshaft. Push the balancer in until it tighten up and it move in anymore.

Now apply some thread sealant or silicon onto the threads of the balance bolt. Screw it in eventually it will start pushing the balancer in.

i usually use an impact on it but don't go too crazy with it can damage the crank.

Go rent the harmonic balancer installation tool at the autoparts store. Lubricate the crank snout and the inner part of the balancer with new engine oil. Align the balancer with the keyway on the crank snout. Press on with rental tool. Return tool and get your money back. Easy. DO NOT USE AN IMPACT AND THE CRANK BOLT!

And don't hammer on it, the crank thrust bearing doesn't like that.

Best method, especially on a quality piece. Heat the balancer in oven on 350 for about 10 minutes. Use welding gloves, and or bbq mits to slide it onto the crank snout, then use install tool, which will bottom in the crank threads instead of the crank bolt which is trying to pull using only a couple of threads... to pull the balancer down to the seal. A quality piece is an interfearance fit. That way the balancer functions to dampen the vibrations in the crank. If it were a drop on slop fit... hot dog down the hallway syndrome.
