Oversize Idler Pulley

91, 4.0, AX-15. When I bought this Jeep the PO said it had A/C but he removed it. I don't believe it ever had A/C because I didn't find any trace of lines or vents. If it did he did a phenomenal job not disturbing anything else. After completing the recent head job I found an extra pulley they had rigged you along with the alt they mounted upside down with homemade brackets. Damn PO's. Now that evening is back together without A/C the idler pulley is squealing like a stuck pig. My mechanic buddy says I may need an oversize idler pulley. I say maybe the pulley itself is bad. Planning on changing it tomorrow, but was wondering if anybody has ever had a need for an oversize idler pulley?

KCCO

a pic or two would help

but no, I've never come across a different idler... I just had to specify A/C or no A/C when replacing the belt (obviously, A/C requires longer belt)

As far as removing it without a trace A/C was a dealer installed item on YJ's so it would not be hard to remove without a trace. The exception being the two holes in the firewall near the heater core where the a/c lines would have come out.

Ahhh...... well I guess it was removed then. I've got them 2 holes and was wondering what they were since they were not in my 94.

I would order the correct idler to go there and get the proper belt. Better to do it right than to keep doing it. I dont have a 4.0 but I am sure someone here has a pic of the non a/c set up they can post so you can see where the idler goes and give you an idea of the correct size.

Yeah a pic would def be nice. I just got back from the Napa in town with a new pulley. I had already purchased a new belt when I put everything back together. Waiting on the Heep to cool a bit before I get working. In the mean time if anybody Has a pic of a 4.0 I'd love to see it

An update:

"Hey Chris did you check everything over? Yeah yeah I sure did. Did you make sure everything was tight? Sure did. Even had a buddy come over and look it all over"

One week and a squealing belt later I find I forgot to tighten the 2 rear bolts on the PS pump. Idiot!

Thanx for the help guys. KCCO!
