WMW 17% not all the way seated
 

Long story short I bought an R53 for dirt cheap for something to play with. Recently did a way motor works 17% pulley (did new idler and tensioner while I was in there) while I had the super charger out for an oil change. Got it all back together and noticed the belt riding about an 1/8 inch off the idler pulley just below the supercharger pulley. I’m assuming I didn’t get the pulley seated correctly. Anybody have any experience reseating these or is it going to be a pain like I have been reading? (I don’t want to have to hack the pulley off and have to buy a new one) I haven’t shredded a belt yet but I don’t drive it daily. I know it’s coming.

Isn't the new pulley attached with threaded bolts and not pressed on, would it not be just a matter of loosening the bolts and seating the pulley correctly? I guess I should ask, which pulley are you talking about?

The supercharger pulley. It is a two piece pulley. I did a little reading and from what I’ve seen after they get heated up they get pretty well seated on.

If its the SC pulley, you should be able to take the belt off and loosen the pulley and mount it correctly.

It's very easy to take back off. Remove the 4 bolts from it. Then take two of those bolts and screw them in the 2 smaller holes in the face of the pulley that are threaded. This will pop it apart and you can re-seat the pulley to have it lined up.

Right on, thanks for the feedback. Everything I read in other forums was dreadful. Guess I was just looking for some reassurance. Will give it a shot this weekend. Probably be ordering a new belt from way as well.

it is easy to do. take your time lining it up!

Even if it's not a daily driver, do it as soon as you can, I shredded 2 belts before getting my 15% seated properly. Live and learn.
