ZZP Over Sized Tensioner help!
 

I am in the process of installing the oversized tensioner pulley. We ground down the ridged area as their instructions state. When we bolted the pulley down and tried to put the belt on - we noticed it will NOT fit. Not even a little bit :( We then ground down the edge of the tensioner arm that bolts onto bracket (best way i can describe it). Still not even close to fitting. I have emailed them for help - I think I may have got the wrong one? But I won't know until they see the pictures. I will post them up in a few.

pictures? we had to grind mine down quite a bit for it to fit

I just posted the pics
Note, we flipped the pulley too thinking we had it backwards, but neither way works.

that does look awful close...once we grinded down the area it said to it fit no problem but we did shave alot off...urs looks lik its about to rub on the top of the tensioner arm..it may be possible u got a wrong 1 but im not sure im no where near my car to look at mine

I'm a little confused by your post. What won't fit? The tensioner or the belt?

the pulley bolted on fine after the grinding. The problem is the gap between the tensioner arm and the pulley on the bracket. the belt will NOT fit between there. it won't fit by a lot too.

bump for more thoughts

To the best of my knowledge these are the part numbers for the oversize pulley. Check them against the pulley you got.
Gates # for oversize pulley 38009
Gm # for oversize pulley 88909590 AC Delco
76mm

Spend the extra money and get the zzp adjustable tensioner worked great on mime

The belt runs over the pulley. It doesn't go inbetween the arm and pulley haha. Look at this diagram. This is how the belt is routed.
