BREEZE1 Posted May 20, 2008 Share Posted May 20, 2008 Hey guys, I know yall can help me on this one. I pulled my old tranny out of the Comanche tonight. I was looking at it and then I looked at the ax-15 and the main shaft seems to be bigger. So I did a little research on the size of the pilot bearings. The old style OD is 1.055 and the ID is .63, the pilot bearing I got for my ax-15 has a OD of 1.00 and a ID of .75!!!! What do I do???? I know there is a fix, I’m sure this has been done a million times or dang near close to it. :mad: Link to comment Share on other sites More sharing options...
Pete M Posted May 20, 2008 Share Posted May 20, 2008 If you're trying to put a later model AX-15 in to replace a Peugeot, then you'll want a pilot bushing from a 70s era CJ. It's a $2 part (which is important because I was offered 2 choices and the expensive one was wrong). Link to comment Share on other sites More sharing options...

BREEZE1 Posted May 20, 2008 Author Share Posted May 20, 2008 Well I have another question for you. The slave cylinder in my old transmission is around the shaft and the ax-15 is mounted on the side of the bell housing. Now what do I need to do, just get a newer slave cylinder? Will all of this hook up fine & dandy? Thanks in advance!! Yall have already helped me a ton!! Link to comment Share on other sites More sharing options...
Pete M Posted May 20, 2008 Share Posted May 20, 2008 http://www.jeeptech.com/convtrans/ax15swap.html If your new trans is an external slave, then you'll need everything that goes inside of it. Nothing interchanges between the 2. The junkyard is the preferred place to get them. And for what it's worth, I adapted my external slave line to the trucks old line using a $2 adapter from the hardware store. Link to comment Share on other sites More sharing options...
BREEZE1 Posted May 21, 2008 Author Share Posted May 21, 2008 I would like to do what you did. But I can't find the lines to go into my new slave cylinder. If I could find them I could cut them and use an adapter like you did. Man I got to get on the ball. I can't stand seeing my jeep sit there with its guts all over my shop. Thanks for your input! :D Link to comment Share on other sites More sharing options...
Pete M Posted May 22, 2008 Share Posted May 22, 2008 Got a picture of what you're dealing with? Link to comment Share on other sites More sharing options...
BREEZE1 Posted May 23, 2008 Author Share Posted May 23, 2008 Ill take some pictures soon and up date my gold member thread. I got lucky, I was talking to one of my buddies the other day and he had an easy fix for it. This guy just so happens to be the smartest man on earth, or at least that’s what I tell him. He always has an easy fix for every thing. Any ways we were talking about it and he came up with a good adapter for my slave cylinder. (I was thinking that maybe I shouldn’t show how I was going to do this so I could make a patent on it. But heck whats the odds of that going threw). Ill show it on my build thread. The only hold up I have now is getting that dang pilot bearing out!!!! Man I rented one of those slide hammers and the fitting wouldn’t fit inside the bearing. I guess I will machine out a rod today so I can knock it out with some grease. I will keep yall updated. Thanks for every thing. Link to comment Share on other sites More sharing options...
Pete M Posted May 23, 2008 Share Posted May 23, 2008 Pilot bearings require a "pilot bearing removal tool". Anyone that has gotten one out using any other method is exceedingly lucky in my opinion. Link to comment Share on other sites More sharing options...
BREEZE1 Posted May 23, 2008 Author Share Posted May 23, 2008 I couldn’t agree with you more, I just can’t find one of those tools around town for some reason. So I turned down some round stock that will fit in it and I plan on beating the crap out of it. So hopefully ill come out triumphant. But to be honest I don’t have much faith in it. :cry: Link to comment Share on other sites More sharing options...
Jeepman Posted May 23, 2008 Share Posted May 23, 2008 Fill the Space Behind the Pilot bearing with grease and Then use some Round stock and Insert it into the pilot bearing Hole now with a Hammer force the round stock into the hole and the bearing will slowly pop itself out... Add more grease and Continue to repeat until the bearing is out... I have done this before and It works but is slow... I have since bought a Pilot bearing removal tool to make the Job quicker and not so messy... Link to comment Share on other sites More sharing options...
Pete M Posted May 23, 2008 Share Posted May 23, 2008 If you try the grease method, make sure you are wearing eye protection. I tried it and had grease squirt out in my face (I had goggles on). Link to comment Share on other sites More sharing options...

I have since bought a Pilot bearing removal tool to make the Job quicker and not so messy... That's how I always did it and never had much of a problem. But being this is a topic of pilot bushings and AX-15's I have a newbie question that I can't find the direct answer to, to be sure, so I'll ask here.. Is my 2wd AX-15 pilot bushing the same size(etc) as my 4wd Ax-15 pilot bushing? Need to double check on my way up to start working on it. Link to comment Share on other sites More sharing options...
BREEZE1 Posted May 25, 2008 Author Share Posted May 25, 2008 well i got it out the hard way, i broke the tool when i rented it. all is well now. Link to comment Share on other sites More sharing options...
Jeepman Posted May 25, 2008 Share Posted May 25, 2008 The Pilot bearing does not change from 2WD to 4WD but the Bearing size does change from 1992 and Up so depending on your Year of Transmisions you are working with... Link to comment Share on other sites More sharing options...

Ok it's from an 89 (Ax-15) and going into a 93. Alright can I not swap in a 89 tranny into a 93 then? I got the measurements for the bushings of both years and they are different so can I not do this swap then? Link to comment Share on other sites More sharing options...
Jeepman Posted May 26, 2008 Share Posted May 26, 2008 You can Swap any Transmission you want to Just Use the Pilot Bearing that is For the Transmission year... And in your Case your Going from a 4.0L/AX15 to a 4.0L/AX15 so the pilot bearing is an over the counter part... Link to comment Share on other sites More sharing options...
