So I am installing a set of Roush UDP's. I am at the install point with the harmonic balancer and am using the OEM installer. The pulley goes on withing an eighth of an inch and all of a sudden the installer falls off. After some inspection, it appears that the threaded end of the installer only grabs a few thread before the shoulder stops further threading. Also, to remove the new pulley, an outside puller is needed as the slots in it are too small for the one that pulled the oem off.The question is, what type of installer should I use? This one fits so deep that it is virtually useless to finish the job.

That is the one I used, but it doesn't grab enough threads.

without seeing the tool, i will need to do this from memory. its been over a year since i did this, so bear with me. cant you adjust the large nut on the installer further back, and thread the rod into the crank?

also, get a light and a mirror and check to make sure you didnt damage the threads on the crank. if they are damaged, you will need to retap the threads. use the mirror so you can shine the light on it an into the holr to be able to see the threads.

The problem is the threaded collar that goes into the crank snout. The shoulder on it comes up snug against the snout and won't go in any further. No adjustment to counter that. I was worried about the threads, but the new crank bolt goes in cleanly. I think I will have to get creative and get some all thread that can get completely threaded into the snout.

Get a longer bolt and flat washer and draw it in about half way, then switch to the permanent bolt and finish drawing it in. Don't forget the silicone.

I am going to use the OEM tool but I am getting a small piece of all thread that will go all the way into the bolt hole. The threads are about 3/4" from the outside of the snout and there is only about an inch before the shoulder hits on the OEM adaptor. Just a little twist that makes home mechanicing (sic) interesting.

I used a 3 jaw puller and had to use a hardened socket to make up the slack between the the rod and the balancer, however I've read that a Chrysler puller works best.

All is well, minus a bit of flesh off of a finger! Thanks for the input. If, in case your every would want to remove the underdirve pulley, an outside puller may be needed, at least on a Roush pulley. The inside slots are mucho small, maybe to small even for a Chrysler puller.

The UDP's i've seen you will need a "bull nose" style puller. If you notice they have 3 or 2 threaded holes in the inside balancer part, the puller arms get threaded in there.

Good to hear that you got 'em on. I am assuming you took it out for a test run so what do you think?

It has always run great. Hard to tell a huge difference at this point. Dyno tune, CAI and cat backs. Next mod is deletes. Then I will go back to the dyno and see what the result is. I will post the numbers when done.
