Serpentine Belt Adjustment

The serpentine belt on my '94 is squeeling pretty bad, and I'm having a problem getting it to adjust. Mine is the 2.5L with AC added, so the adjuster is under the PS Pump. I've loosened the Pivot Bolt and the Adjustment Bolt, but the Adjustment Screw does nothing when screwed in or out. Am I missing a step, or doing something wrong here? Even with the Pivot/Adjustments Bolts loosened, the PS Pump does not move at all.

Also, did notice that the Adjustment Bolt Collar is broken (I'll pick or order a new one at work tomorrow). The pump does not move, even with this part missing, and the Adjustment Screw removed.

Any help will be much appreciated.

I had to loosen the bolt in the center of the adjuster idler then turn the adjusting rod to tighten the belt... once done, besure to tighten the bold in the center of the idler wheel that you loosened.

There is a bolt hidden on the fire wall side that needs to be loosened. It is a pain to find, you will see it from under your YJ.

Do yourself a favor, and take the entire bracket/adjustment mechanism apart. Clean lube, and reassemble.

Then, it might actually work.

Mine has 2 bolts on the backside that get loosened, 1 on the top pivot and the 1 under the pulley that locks the adjustment bolt.

I see the bolts you folks are refering to on the backside (why can't Hayne's mention these in it's adjustment proceedures). I'll mess with this more on my next day off, have to replace the broken Adjustment Bolt Collar first. I'll also be cleaning the whole assembly, and putting some anti-seize on it as well.
