Q's Jeep Posted August 28, 2011 Share Posted August 28, 2011 Just got my first MJ 89 4x4 4.0 AW-4/column shift. What is involved in relocating the alternator due to A/C comp is shot. Not going to retro the a/c . Or is there a idler pully assembly available to replace the a/c comp ? Thanks Link to comment Share on other sites More sharing options...
jimoshel Posted August 28, 2011 Share Posted August 28, 2011 There's an idler pulley that bolts on to the AC mount. Link to comment Share on other sites More sharing options...

Q's Jeep Posted August 31, 2011 Author Share Posted August 31, 2011 Where can I get on of these pulleys or a part number ? Called a couple of the local part stores had no clue what I was talking about. Any help would be appriciated Thanks Link to comment Share on other sites More sharing options...
jimoshel Posted August 31, 2011 Share Posted August 31, 2011 Should be able to find one in the junk yard. The 2.5 and 4.0 are identical. If you can't find one , let me know I've got a couple. I'm not sure but I believe the V8's would also fit as the compressors are generally the same and it will just bolt onto the mounting adapter.

xjrev10 Posted September 26, 2014 Share Posted September 26, 2014 TTT I'm gonna do this when I replace my alternator in my project. Anyone have any more input? Link to comment Share on other sites More sharing options...
yxmj Posted September 28, 2014 Share Posted September 28, 2014 Take a moment and Google the YJ 4L set up......I do not have a pic but my YJ alt (HO 4L) is (when viewed from the front) on the upper left hand side of the motor.....same spot as the AC or idler pulley in my XJ's.......better spot IMHO if you do not have AC......easier to work on and keeps it out of the water when you decide to take a swim Link to comment Share on other sites More sharing options...
xjrev10 Posted September 29, 2014 Share Posted September 29, 2014 Right. That's the plan. So HO YJ alternator bracket is the key for a Renix? Link to comment Share on other sites More sharing options...
yxmj Posted September 29, 2014 Share Posted September 29, 2014 Check for TJ as well....I think they would be the same ....and probably easier for you to get....Google some pics and you will get some idea's :thumbsup: Link to comment Share on other sites More sharing options...
xjrev10 Posted September 29, 2014 Share Posted September 29, 2014 I guess I'm more or less trying to get away from any fab. It has to be perfect. I have trouble with perfect. Ha Link to comment Share on other sites More sharing options...
yxmj Posted September 29, 2014 Share Posted September 29, 2014 Well by rights it is the same block.....if you had the factory parts there should be no fab needed Link to comment Share on other sites More sharing options...
metrictonner Posted September 29, 2014 Share Posted September 29, 2014 Stock 4.0 with or without A/C used same belt. Link to comment Share on other sites More sharing options...
yxmj Posted September 29, 2014 Share Posted September 29, 2014 If you get this idler set up (off a 2000 wrangler no air) ....i think you will get the result you want. But you will probably have to get the same era belt yours will not fit............... But there are more ways than this to do what you want......if you can look back at old 4.2.s they had the Alt up high on the left Link to comment Share on other sites More sharing options...
