Swampy Posted April 18, 2018 Share Posted April 18, 2018 Hey guys I need help to fix my belt issue. My comanche has shredded 2 belts and I want to come ask before I go buy another belt and it gets shredded again. I was looking at my pulleys and it looks like my alternator is not aligned. Is this the cause of the problem? If so how can I fix it Link to comment Share on other sites More sharing options...
MuddFoot Posted April 18, 2018 Share Posted April 18, 2018 Looks like it's the alt. I'd also check the harmonic balancer.Sent from my Z981 using Tapatalk Link to comment Share on other sites More sharing options...
Jeep Driver Posted April 18, 2018 Share Posted April 18, 2018 Is that a 88 2.5? Something there does not look right. AC? Link to comment Share on other sites More sharing options...
Jeep Driver Posted April 18, 2018 Share Posted April 18, 2018 This is how the '88 is set up, any other way and it is not stock. Link to comment Share on other sites More sharing options...

It does not have mpi so its definitely renix. Unlike your engine my ac and alternator seem to be switched with an idler pully next to the alternator. I read somewhere that this switch was done either from factory or after for better water foarging abilities but idk Link to comment Share on other sites More sharing options...
Swampy Posted April 18, 2018 Author Share Posted April 18, 2018 This is the best picture I have at the moment. You can kind of see the ac under the alternator and the idler pulley i was talking about Link to comment Share on other sites More sharing options...
HOrnbrod Posted April 18, 2018 Share Posted April 18, 2018 The alt pulley definitely looks out of alignment and it also looks new. Did you recently replace it? If so, where did you get it and what's the p/n? Link to comment Share on other sites More sharing options...

IOWs just the same as mine less the compressor. Link to comment Share on other sites More sharing options...
Jeep Driver Posted April 18, 2018 Share Posted April 18, 2018 Strange, never seen this before. This is the only one I can find that resembles yours, and his looks cobbled together. The only thing I can tell you is to use spacers or washers to bring the alt out and in line. Jump ahead to about 6:00 Link to comment Share on other sites More sharing options...
Jeep Driver Posted April 18, 2018 Share Posted April 18, 2018 Later model MPI has bracketry like that, MPI accessories are closer to the block, Renix is further from the block, that might explain why the alt is in closer. Link to comment Share on other sites More sharing options...

Its definitely weird. As I am trying to figure it out, it explains why the 2.5l belt from rockauto.com was too short and didnt fit. And similarly to that youtube video you linked. My alternator falls into a bracket that doesnt really make it possible to space it foward Link to comment Share on other sites More sharing options...

Don't matter - it's out of alignment causing the belt shredding and needs to spaced forward. Link to comment Share on other sites More sharing options...

My alternator falls into a bracket that doesnt really make it possible to space it foward Yeah, I see that. May have to cut and weld..........IOWs move the mounting point out about 1/2".....or whatever the difference is. I have the actual alt bracket on ebay but you need the AC delete..........you don't want to pay my price anyway. I'd suggest you look for an alt bracket and AC delete bracket and set it up the way it's supposed to be. May take you a while to find the parts though. In the mean time....cut and weld.

Swampy Posted April 18, 2018 Author Share Posted April 18, 2018 Is there another way besides cut and weld because I don't have a welder on hand. Also how does his setup in the video seam to be in alignment I am sorry I am bothering so much I just wanted to try and fix it Wednesday morning Link to comment Share on other sites More sharing options...

Swampy Posted April 18, 2018 Author Share Posted April 18, 2018 I should still ahve the old alternator so I will look at it and see if there is any difference. Would I pe able to just space out the pulley part? Link to comment Share on other sites More sharing options...
Swampy Posted April 18, 2018 Author Share Posted April 18, 2018 Upon further inspection, the pulley itself on the older alternator seems farther out, i will grab some pics in the morning Link to comment Share on other sites More sharing options...

IOWs just the same as mine less the compressor. There were 2 alternator versions of the 2.5 buddy of mine had a no a/c and the pulley was shorter and couldn’t get it to line up like swampy situation now (he had an a/c equipped alternator) the non a/c version had almost a thicker rib as extender to bring the pulley out to line up with all the accessories someone here had that same issue a LONG time ago and I found it to help my buddy... let me see if I can find the thread Link to comment Share on other sites More sharing options...

88whitemanche Posted April 18, 2018 Share Posted April 18, 2018 in this thread shows the same set up as swampy's that has the alternator pulley with the extra thick rib to extend out the pulley Link to comment Share on other sites More sharing options...
Jeep Driver Posted April 18, 2018 Share Posted April 18, 2018 interesting. 7 years of looking at parts engines, belt diagrams, pics......etc..........this is the first I've seen of this. In your first link, that is the AC delete that I've seen plenty of...........Swampy's, this is the first. Why? same model year? No answer for that. Better find that pulley.

Spoke to him already, luckily he has his old alternator and he’s going to swap pulleys Link to comment Share on other sites More sharing options...
Swampy Posted April 18, 2018 Author Share Posted April 18, 2018 Yup I found my old alternator in the bed of the truck noticed the pulley was pushed out farther, swapped the pulleys and everything is aligned properly now.
