doing a pully swap next weekend and i have evrything but the pully puller figured out. can i just use a standard puller, like a 2 arm or 3 arm or crows foot, to remove the stock unit?

 

I always thought a good puller would work. I did end up buying one from outmotoring though. When I did my pulley I was happy I had. Keep in mind the worse that can happen is you destroy the stock pulley and have to grind it off. Or even worse bend your shaft. There isn't alot of room behind the pulley for big feet, or alot of room infront of it for a big puller.

 

but if i dont have time to get one from outmotoringor alta, a 3 arm puller will do the trick?

 

Can you get a bearing spreader in behind it? That will work far better than a three arm puller.

This is a bearing spreader for those who don't know the term........

 

that would work great, not sure on the fit i will have to look around.

 

Could you use a standard puller? Maybe... although I've never heard or seen it done... as mentioned, there isn't much room. Also, I don't think there is enough space between the pulley and the s/c housing for the puller claws. All of the purpose-made pullers/adapters grip the pulley by the belt grooves.

I have the version that is similar to the one sold by MiniMania, although only because I bought it used for cheap. It does work - I used it a few weeks ago - and has the advantage that its compact size doesn't require removal of the engine mount bracket. The down side is it doesn't grip the pulley as well as the clamp-on styles so you have to be damn sure it's on properly or you will destroy the stock pulley, thus making the car undrivable and your life bad. Were I planning to do pulley installs more often, I'd buy a full-contact version.

The ultimate consequence of puller failure: wrecking the supercharger shaft.

 

ok, ill see what i can do, any alternatives for a colar?

 

I was just searching for info about a puller for a JCW pulley (99.9% mine won't work for a smaller pulley) and came across this thread:

freeskier, be patient and wait till you have a proper groove clamping puller.

IanF, I milled down a P & D style (machined by expatriate holdenontoit) pulley clamp to fit the JCW pulley.

 

so can i buy the grooved colar locally?

 

What's "local"? I'm sure there are MINI owners spread across the country that would be willing to loan you a puller.

 

im near boston, if anyone in the boston area has a removal tool that they would be willing to let me borrow, that would be great.

 

Try our regional club: www.nemini.org I forget exactly who has what, but someone should be able to point you in the right direction.

k-huevo, how/where did you mill the clamp? Does it maintain full contact around the entire circumference of the pulley?

 

IanF, how – giant industrial mill, where – the clamp half without threads. A little extra material was removed, I then shored-up the gap with washers for rigidity and to adjust for varying tolerances. It doesn’t grip the entire circumference, but it grasps enough to remove the pulley without deformation.

 

I used a three clawed puller just fine There was enough room inbetween the pulley and supercharger to fit. Good luck with your install. Took me five hours to get everything done. Its not very hard to do as long as you take your time.

 

Even if you can find a three clawed puller that will fit between the back of the pulley and the supercharger; you are taking a risk of screwing up the lip on the back of the pulley and warping/ bending it up before you actually get it completely off the shaft... then you have to worry about cutting it off without damaging the shaft too much; cuz then you have to buy a new supercharger. So... just do like me if you don't want to spend alot on the right pulley; put out a thread in the marketplace to rent one from somebody for cheap

Remember... anything that CAN go wrong, WILL go wrong

 

I used a two jaw "tie rod puller". It keeps more leverage on the jaws to keep them in tight to the pulley. The center also has a bearing so as not to damage the center shaft. Worked OK, initially was hard to break loose, fine after that. Pulley was not reuseable. Round file!

 

ok thanks guys im gonna get a bunch of pullers togather this weekend and try it.
