Supercharger Pulley Puller

[RigDotCom]

Does anyone have a supercharger pulley puller that can give me dimensions? I have access to a full machine shop with a lathe and a mill and a ton of scrap steel. I know they sell them and where to buy them, just want to try my hand at it.

I have a ton of bearing pullers but it's a bit absurd to spend $250 removing a <$200 part 1 time.

The back of the s/c pulley is angled. A traditional puller will not grip it properly and will most likely slip. The good s/c pulley pullers are machined to fit into the seven grooves in the pulley itself, sort of like a mold would be for the pulley. That is where they grip. You would need an OEM s/c pulley to get those dimensions, I would think. That would let you make a clamshell that then would attach to your more traditional gear or pulley puller, or be machined with a threaded center section for your puller bolt to go through. You will be gripping the pulley from the sides rather than the back.

You can buy cheap supercharger pulley pullers, I got one for £12 from eBay. Because its not S4 specific it didn't fit without removing the supercharger, but I was doing that anyways to change the thermostat.

Something like this should work, right?

I have the APR pulley removal tool which I have loaned out multiple times.

Nope. Wish it would. Not even possible to put it in place and have room for the center bolt with the supercharger still on the car. And, you can't pull it from the back of the pulley. It will slip off. Nothing there flat to grip. You have to have some sort of shell to encircle and contain the pulley by its grooves or a two piece clam shell to grip it from the sides that then attaches to a threaded hole in the front.

I have all sorts of pullers in my shop. Supercharger pulleys are a different breed. Conventional pullers will not get in this tight space and will not grip the pulley properly. There might be other ways to pull it if you have the supercharger completely off, but most of us will not be doing that.

They are going to look something like this, or similar but with two clamshell halves. The one I rented from EPL looks just like the first one below. It grips the pulley grooves from the side and is very compact to allow it to fit onto the pulley with room to turn the center bolt.

The APR version grips the inside lip of the pulley, front and back and forms a shell completely surrounding the pulley, rather than trying to grip the pulley from the outside back.

See how this one relies on the internal ridges of the tool to fit precisely inside the supercharger pulley grooves?



Two piece clam shell tool - same principle but completely enclosed around the pulley. Either works, but you must grip the pulley grooves or encase the pulley from the side between its front and rear flanges, rather than try to grip from the back.

This is the type I used but you'd need to remove or at least lift the supercharger a little to have room for it.

Hey, I'm in McDonough. I didn't realize how close you were. I need to borrow that puller. I can compensate you. 404-271-8083 Riginald.
