In the York air compressor install for 90 YJ (4.2L) the belt routing changed. One of the idler pulleys needs a bearing replacement. The existing pulley does not have a "user serviceable" bearing. I see no part number on the pulley. I'm trying to locate the pulley and could use some help. I have no idea what make/model Jeep I should be searching under - 1985 Wagoneer with Factory air???
The pulley is for the air conditioning belt and is the silver colored top right pulley on the A/C belt in the attached photo (which is not my jeep). Also attached is a pic of the pulley I have (bearing is crimped into the pulley housing). The version in the pulley photo shows what looks like an open-faced pulley with a push-in bearing with a bolt going through the pulley - a different style - not that I care - so long as I can find one that fits (user replaceable bearing a plus).
Searching shows these pulleys as possibilities - though I'll likely need some sort of spacer for the bolt that passes through the bearing ID.
One step forward... I found a part number for the pulley I have... J321 7201. Now to either find one or to find the replacement. This could be a simple call to the local Jeep dealer to buy it from them (or maybe see what supersedes this model and is current).
Supersessions!! J3173164; J3143732
Any help is appreciated. At this point I am unable to find any source for the two new part numbers - or any picture of either part number.
