I am about finished with this engine. I have it back in and got everything hooked up to it. Put an alternator on it and then went to put belt on it. That is when I noticed the belt line was off a bit between the crank pulley and the water pump. I noticed the hamonic balancer was off slightly and just figured he had not installed it all the way on. When I got my installer out it would not go in it. On closer examination I noticed the thread are buggered up on the inside. It there anyway to fix this? Can I re-tap a slightly larger thread? What should I do? The guy I bought it from has disapeared. If I could just get the harmonic balancer in the right place i would be done with this project.
