Strokermjcomanche Posted April 21, 2015 Author Share Posted April 21, 2015 My truck has the ba 10 in it now . Are they different ? Link to comment Share on other sites More sharing options...
Megadan Posted April 22, 2015 Share Posted April 22, 2015 Yes. The mount platform on the AX-15 crossmember is lower, and it sits a little further back on the frame of the vehicle. Luckily, the holes are already there for it, but you will need to drill and tap. You may also need to drill two out like I did. I used large nutserts of the same thread type as the factory holes and welded them in place with a bunch of tack welds and ground them flat. A bit overkill given the ones I used had knurled edges, but I wanted to make sure they wouldn't move.I did a BA-10 to AX-15 swap about a year ago.On the up side, I believe you can use an XJ trans crossmember as well. I managed to get my hands on a Comanche one for cheap, but they are a bit harder to find. Do a search on the swap and you can find quite a bit of info on it.

Strokermjcomanche Posted May 8, 2015 Author Share Posted May 8, 2015 Well I scraped the ax15 swap and picked up a nv3550 out of a 02 Tj to put in with 89k for 500 . He gave me the trans mount and bracket and transfer case linkage as well so at least I have something to modify if I need to . So here is yet more questions : What clutch will I use ? The one for the Tj or the Mj /xj with a ax15 ? The splines and diameter of each clutch are the same from what I can tell but I won't be sure what the bolt pattern of the Tj clutch plate is to match the renix flywheel until the old trans is out . I'm sure that I'll have to use the throw out bearing from the Tj , but would like to know which clutch to purchase ahead of time . The pilot bearing seems to be the same between the two trans with 1.055 O.D. And a 7.50 I.D and is included in the Tj clutch kit 1890-05 . I've read on a post that the nv3550 is an inch shorter than the ax15 ? So that means a custom/ shortened front driveshaft or the ax15 shaft or Peugeot shaft will work ? Thanks in advance for the help advice . Link to comment Share on other sites More sharing options...
Eagle Posted May 8, 2015 Share Posted May 8, 2015 The only part of a clutch assembly that makes any contact with the transmission is the splined center hub on the disk. The pressure plate, which is the part that you bolt to the flywheel, obviously has to match the flywheel. Link to comment Share on other sites More sharing options...

I understand that ^^ much and was hoping that someone that may have done this swap before would shed some light on what clutch they used or problems they had etc etc . I'd like to have all parts in my possession or at least enough parts that I can bolt the trans and tcase before I start taking the truck apart . I apologize for not being clear . I hope I'm not overthinking this . Thanks again Eagle Link to comment Share on other sites More sharing options...
87MJTIM Posted May 9, 2015 Share Posted May 9, 2015 From experience :oops: , get a clutch to match the trans, not the engine. I did an AX15 swap into a CJ7. I bought a clutch kit for the engine (4.2L/258). The clutch grabs/releases all the way at the top. The pedal does not go to floor. I researched part numbers on Rockauto for the clutches used in diff jeep and the known trans. The AX15 started with the intenal slave cylinder then switched to external in 94. The part numbers changed with that model change. I have to change the clutch in the CJ now. :( Link to comment Share on other sites More sharing options...

Strokermjcomanche Posted May 26, 2015 Author Share Posted May 26, 2015 Can't find a local ax15 xj /mj crossmember . But I did find a Full Traction #720646 Xj crossmember with the description stating that it was good for a manual . Anyone ever used one ? It looks well made .Image Not Found Link to comment Share on other sites More sharing options...
Megadan Posted May 26, 2015 Share Posted May 26, 2015 I haven't used it, but I really like it. At $379 though, sheesh. I'm sure it's durable, but wow... Link to comment Share on other sites More sharing options...

I can get it for $160 brand new . I've seen the 1inch dropped crossmember go for $ 150 with no skid plate . I'm open to anything really . Thanks for the reply .

88whitemanche Posted May 27, 2015 Share Posted May 27, 2015 Check out the rustys ax15 1" drop HD crossmember Link to comment Share on other sites More sharing options...
Strokermjcomanche Posted May 27, 2015 Author Share Posted May 27, 2015 Thanks ,I just looked at it . I noticed that according to the stock picture that rustys crossmember only bolts with 4 bolts total vs the one I'm looking at that looks like 8 mounting bolts like the original . Is that right?
