Revisiting the underdrive pully topic for fresh info.

The tool is for holding the original pulley in place so that you can get the bolt undone. As I mentioned in my earlier post the bolt is VERY tight and you need a lot of force.

The "boss/block" is part of the engine block. Due to the different design of the original pulley and the RSS pulley this boss is in the way of your new pulley and has to come off, you'll see! Use a hacksaw, much easier than a Dremel or such.

Basically totally easy to do, bolt is the hardest part....

Good luck!

You are going to need a different belt when you finish as well.

Already have the updated smaller belt for the RSS UDP.

Did you guys reuse the pulley bolt? I read on one of the UDP manufacturer sites that you need new bolt and should not reuse the old bolt.

My Wrench is 14 inches long so it has lots of leverage, but I still couldn't get that bolt open. I will hit the wrench with a hammer to see if that helps.

So is it easy to saw off? RSS said that it was an easy installation no extra tools required. Liars.

i am getting ready to do this and i went with the RSS kit and shorter belt. I have not installed it yet , hopefully soon .

I'm interested in this as well. Where do I buy the kit with the pulley, belt, and tool?

BBI AutoSport, Road Sport Supply and Jake Raby all offer excellent LWUD pulleys .

Guys, yes that bolt is on there tight, but it was a very simple removal using leverage.

Use your ratchet, or better yet, breaker bar, coupled with a long stick/pole. I used the long metal one that is used on floor jacks (depends on the type you have). Mine was perhaps roughly 3-4 feet long with a hollow end that I was able to slip over the ratchet/breaker-bar. Didn't require much force to remove at all, using this leverage.

And if you don't have the pulley holding tool, depending of the type of pulley you purchased, you may not even need one. For the 4" pulley I installed, I just slipped a bolt through one of the holes in the pulley through the hole in the block to hold it in place.

Hope his helps!

Still trying to find out. Did you guys reuse the old bolt that was holding down the oem pulley?
