I have a 96 z28 lt1, i put a ac bypass pulley! It keeps eating belts if u look down and line the pulleys up its not it line with the other pulleys? Are thay suposed to come with shims or suposed bolt up and no worrys? This is the 2nd one i have a had on it and still doin same crap! Just curious if ne of you guys have hade this problem! Thanks

If it looks like it needs to be spaced out a bit, just used some washers in between the acc bracket and the bypass pulley.

Thats wat im guna do i was just curious if neone else has had this problem

What brand pulley do you have? I will be ordering one in the next day or so and would like to avoid your problem

I've heard of people with cheap bypass pulley's having to shim it. It's not a big hassle at all. When you install any pulley, you should use a straight edge or make sure it lines up with the rest of the serpentine system by some other means.

K thanks bro, i figured it wAsnt but u learn as u go!

Auto zone! But have a buddy that works there and just gave it to me so i dont reccomend doin so lol!!!!

I bought a bypass pulley from Advance Auto, it looked to line up straight to me but just yesterday I started getting a squeak from under the hood, I think that's the cause, it's only been about 1000 miles. I'll be looking into it tomorrow and see if the alignment is off with the other pulleys.

I had the same problem and I am going to have to shim mine a tad. I have the braket with tensioner and delete pully on the bracket out of the car right now and they don't quite line up to wear the belt seems to be riding on the tensioner.

Mine look to line straight up to and im still tinkern with mine hasnt ate another belt yet but its starting to fray ive been adding and subtracting washers as needed and finally think i got the bitch let me no eat u half to do bro!!!!
