underdrive pulley
so i've got an unorthodox racing underdrive pulley coming in the mail tomorrow, and i was wondering: do i need any special tools to swap this? i was thinking there was a thread before that said you need some special something, but that was forever ago, and now i can't seem to find the thread.

RE: underdrive pulley
Here is a link that should help you. And you'll have to let me know how the install and how it runs afterwards, I'm looking to get one of those. I see its not the same one you have, but it should give you an idea of what you need to do it.

In short, you will need a special tool, and it can be rented for free from Autozone.
There are posts on here that suggest a slide hammer will work. Well I hammered away at the thing for 30 mins and it did not budge a single millemeter.
I then preceeded to snap a regular 2-ton and 5-ton 3 jaw puller, taking a gouge out of my thumb from a chunk of flying broken metal in the process. Make no mistake that buggar is on there tight!
The special tool is called a "Chrysler/Mitsubishi Harmonic ballancer puller". It is made for the job, built like a sherman tank and will get the job done. It has a special insert so you will not knacker your crank threads, and it has a hex welded to the body of the tool that you can use to keep the pulley steady while you tighten the puller.
Wear eye protection just in case!
Good luck,
Dave

RE: underdrive pulley
okay, so i've been out of town for a while, but i finally got a chance to swap out my underdrive pully. here's the deal, though. i got the harmonic balancer puller. it's the same idea as the steering wheel puller i used on my old ranger way back in the day, so i know how it's supposed to work. my problem is my underdrive pulley, the stock one, doesn't have the threaded holes in it which would be necessary for the puller to work. did i get the wrong puller?[sm=dontgetit.gif]
