64 Cheyenne Posted April 13, 2013 Share Posted April 13, 2013 So I'm putting an HO in the 87, I'm going to keep the Renix engine controls and will use the HO intake and accessories PS pump, alternator etc. What do I do about the AC pump? Don't really want to leave it in place...Not doing any type of engine powered OBA, as I want this truck running this year.Besides I bought a CO2 system on the cheap that I can swap between trucks if needed. Did HOs Come with a non AC idler like the Renix non AC did? Already got the alt and TPS figured out so not the issue here. Link to comment Share on other sites More sharing options...
onlyinajeep726 Posted April 14, 2013 Share Posted April 14, 2013 Go to the junkyard and snag you one of these (the one on the left I mean, if you don't already have one coming with your HO). Then go to the parts store and get one of these... It's a Dorman A/C bypass or A/C delete pulley. Link to comment Share on other sites More sharing options...
64 Cheyenne Posted April 14, 2013 Author Share Posted April 14, 2013 Thats cool, got a part number for the Dorman? Did a search, ebay, summit, rockauto, they all show the square shaped one is for 96 up. Will that work for my 95? Link to comment Share on other sites More sharing options...
onlyinajeep726 Posted April 14, 2013 Share Posted April 14, 2013 It shouldn't matter what year your HO engine comes from because the casting for that bracket (in the first picture I showed) is the same for all 4.0L blocks. What will make a difference is what year that bracket comes from. If you are only able to find the Dorman bypass pulley for a '96, then go to the junkyard and find that bracket off of a '96. Although, I will say this much, that one in my picture that says it's from a '94 doesn't look any different than a '95, '96, and so on. When I dropped a stroker in my XJ recently, I was at the junkyard getting some parts and came across an OEM bypass pulley, and pulled the whole bracket and everything. Can't quite recall what year the donor XJ was, but I believe it was somewhere around a '94-'96. Link to comment Share on other sites More sharing options...
