Default Idler Pulley Replacement

I was wondering if anyone has replaced the idler pulley on their cherokee? It's the pulley that is under the power steering pump. I have a 98. I called the parts store and they said it's a dealer item. The dealer is saying I need to replace the tensioner and pulley together. Is this true or can I just replace the pulley?

Thanks for the help.

Wayne

I just did mine on 96xj the pulley under the power steering pump is the tension pulley. loosen the bolt on the pulley then loosen the bolt that is on the topside of pulley bracket just to the left of power steering pump. This will loosen the tension on the belt to remove it. Now when you take off the pulley a thick washer might drop so catch it and reuse. reassemble like this. Put bolt threw pulley, then the thick washer, thread into tensioner bolt but just till it is snug, tighten the tensioner bolt till you can not turn the power steering pulley by hand, then loosen the tension just until you can turn the power steering pulley with some resistance, this should give you the rite tension without squeal. then tighten the tension pulley to spec torque. If you start it and have a squeal you need to loosen the bolt on the pulley and adjust the tension bolt to either loosen or tighten the belt,[ they are picky] and then tighten the pulley again. The tension bolt will not work unless you loosen the pulley bolt so dint try to just turn the tension bolt to adjust without loosening the pully first,. Hope this help

The top bolt, you'd prolly break the belt first.

The front bolt.....yeah, I made sure I was careful with that one.

Thank you, I didn't realize you had to loosen up the pulley bolt to adjust the belt tension. I replaced my belt without doing that before. But, I will be sure to keep it a bit loose while adjusting the belt now.

Thanks again,

Wayne

I looked but couldn't find the torque spec. If I find it, I'll post it.
