ASP Pulley
Hello, Im ordering an ASP pulley as soon as the new ones are ready to be shipped out. Im not really to good with toold so I was thinking about taking the car into a local mechanic to get it done. Does anyone know of anything I should let the mechanic know of for installing the pulley? Also what belt size should I tell them to go for or would the mechanic know which one to use?

Get the new steel hub version. It's $300 U.S. The belt you can buy at any auto supply store. Got mine at Pep Boys for $18.99 U.S. Just ask for a 6 rib 56" belt. Also pickup a K&N or ITG drop in panel filter for an extra 3HP.

Sure, if you truly don't know what you are doing and modify the pulley to make it easier to install like a few have. Did you know that some pulleys are coming back to ASP so badly sanded that it's a wonder they haven't failed. He said he won't warranty any modified pulleys whatsoever. I can't believe how lazy people are. The pulley is a press fit, it's not supposed to glide on effortlessly. But morons sand the heck out of the hub and this creates vibrations and can lead to a failure and damage the key. For all I know they hammer it in. The proper way is to align it with the key and use the bolt to ease it in. I can see why Renntech and Kleemann insists on a professional installation to maintain the warranty. I have a picture of a modified pulley at work and I'll post it to show how stupid people can get. Then when it breaks they blame ASP. To those people, please buy a Kleemann pulley!
If any of you sanded the hub for an easy fit, remove it at once and send it back to ASP for the free steel hub upgrade and if you have trouble installing it, take it to a professional, don't sand it.

I sanded mine just a bit to make sure it was perfectly smooth and wouldn't cut into any seals. But it's stupid to sand it just because you want it to go in easier. The stock pulley being relatively hard to get out should be some indication of how tight it needs to be.

Buel,
So in short it is operator's error in installing a pully when it fails!

I hope wherever I take it they dont do it the easy way and cause me problems latter on. I will make sure to tell them not to Sand it. Also what exactly should they remove in order to get it installed correctly.

It's not terribly clear to me what they did. Is it that big chamfer that they added or those gouges inside?
Either way, sanding is something that you do to wood furnature so that you don't get spinters. I don't know why people are sanding "precision" machined aluminum parts. If there's a burr on the diameter, then it should polished out with emery cloth or carefully knocked off with a swiss file. Sanding the ID is like sanding the cylinder bores in order to get the piston rings to fit in...

Sorry, didn't take the picture but what it shows is that half the hub was sanded specially down in the keyway area where it's very thin. You can see that the area in the hub is not black as it came from ASP. Also note the keyway is virtually gone in the sanding. Sanding not only weakens the hub as you are removing the hard annodized coating but sanding it the way this individual did it throws the hub off center. If this pulley didn't come back in for a new hub it likely would have failed. Young, you at least realized that you were in no position to install it yourself and galdly pay someone to do it. I think with halfway decent mechanical skills and with the assistance of the many that did install it themselves on this forum one can install it themselves.

When I had the pulley I only sanded the outside surface of the steel ring with 1000 grid paper, in an attempt to smooth it more because I had a leak before. I will never sand the inside though.
