I had to pull the harmonic balancer of my daughterÆs car. I bought a cheap pulley puller and made it work. It took a lot of wrenching with a cheater bar. I would recommend buying a Craftsman pulley puller from Sears. More money, better quality, easier. Your can rent these also, but its cost almost as much to rent as to buy.

To install the pulley you can get it started buy tightening the pulley bolt that threads into the crank. I made a tool out of 1/4" X 1" flat bar 24" long. About 16 inches from one end I drilled a pivot point and attached another piece 8" inches long. It makes a kinda scissor joint. On the end of the two pieces I installed a 2" stud bolt.

The stud bolts should slip into the slots on the pulley. It forms a spanner type wrench that holds the pulley while you tighten the pulley bolt.
