stripped rotor or tool

Post by Jim Hyman » Sun Jul 21, 2002 12:50 am

Dennis, Here is a possible solution for removing the rotor puller tool. This should work if you have several threads showing on the outer end of the puller tool. You will need a large nut that has the same thread pitch and diameter as the rotor puller tool. Cut the nut in half from the top to the bottom and use a thread file to clean up the threads from the saw cut. Each nut half should now look like this: \_/ Place both halves of the nut on the puller's threads, as close as possible to the rotor. Use vice grip pliers to hold the nut halves in place. Slowly rotate this nut in a clockwise direction until it bottoms against the end of the rotor. Now you will try to remove the rotor puller tool (counter clockwise) while you gradually rotate the the nut in a clockwise direction. Fred is correct, after the puller has bottomed against the end of the crankshaft, it is accepted practice to hit the end of the rotor puller tool while turning the puller to pop the rotor. It is NEVER ok to hammer on the rotor itself. Under normal circumstances, I apply rotational force to the puller while I moderately hit the the end of the puller. I also apply anti-seize to the inner tip of the rotor puller and its threads. I don't recommend using a slide hammer or jaw puller. If this doesn't work, I have one other possible solution, but it's a bit involved. Contact me off list if you need more help. Professor ps: I trust the merchant AND the machinist, but who am I to stand in the way of a Utah style civil war. ++++++++++ Fred wrote:

optimize n' synchronize

Thanx Professor- I figgered it would be more complicated than looking at beach bunnies.(Dayum!) Has anyone expanded the airbox intake and then adjusted the carb? If so, how much change in air volume to what changes in the carb settings did you end up with. Hopefully this would give me reasonable guidelines to help get me closer sooner w/o disastrous mistakes.
