Alternator relocation question ???

[Q's Jeep]

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

There's an idler pulley that bolts on to the AC mount.

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

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.

I think I remember reading a thread which listed the new serp. belt number that was needed also, but i can't remember where i saw it.

TTT

 

I'm gonna do this when I replace my alternator in my project. Anyone have any more input?

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

[xjrev10]

Right. That's the plan.

 

So HO YJ alternator bracket is the key for a Renix?

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:

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

[yxmj]

Well by rights it is the same block.....if you had the factory parts there should be no fab needed

Stock 4.0 with or without A/C used same belt.

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
