87manche Posted February 19, 2007 Share Posted February 19, 2007 it's a 2wd AX-15, yes it's an internal slave, and you can bleed it. Link to comment Share on other sites More sharing options...
88swampedmj Posted February 19, 2007 Author Share Posted February 19, 2007 damn i hate internal slaves.. well i guess ill bleed it and see what happens... oh is it a 23 spline tranny? Link to comment Share on other sites More sharing options...
Eagle Posted February 20, 2007 Share Posted February 20, 2007 damn i hate internal slaves.. well i guess ill bleed it and see what happens... oh is it a 23 spline tranny? ????? It's a 2WD, right? Normally when we talk about 21-spline or 23-spline we're referring to the interface with the transfer case. You don't have one. Are you asking about the spline count on the tranny input shaft, that the clutch disk rides on? Link to comment Share on other sites More sharing options...
88swampedmj Posted February 20, 2007 Author Share Posted February 20, 2007 yea so incase i may need another tranny Link to comment Share on other sites More sharing options...
mjeff87 Posted February 20, 2007 Share Posted February 20, 2007 AX15 input shaft is 10 spline x 1-1/8" (same as the BA10/5). Jeff Link to comment Share on other sites More sharing options...
fiscus Posted February 20, 2007 Share Posted February 20, 2007 AX15 input shaft is 10 spline x 1-1/8" (same as the BA10/5). Jeff Not all are the same, but in a 91 they should be the same. I have a 91 2wd 5-speed (in great shape) pulled & ready to go, but you're a little far away... we just did a 4wd conversion on a 91 XJ. Link to comment Share on other sites More sharing options...
88swampedmj Posted February 20, 2007 Author Share Posted February 20, 2007 is my clutch the same as a 94-01 cherokee/wrangler 4.0 clutch? or should i look for one 89-92 or somethin? i figure mine is a high output motor ax15 so shouldnt a 94-01 clutch fit?

88swampedmj Posted February 20, 2007 Author Share Posted February 20, 2007 yea i was lookin on ebay for a new clutch set up they come with the clutch disc pressure plate and slave cylinder.. i may get one if bleeding doesnt work.. Link to comment Share on other sites More sharing options...
JeepcoMJ Posted February 20, 2007 Share Posted February 20, 2007 yea i was lookin on ebay for a new clutch set up they come with the clutch disc pressure plate and slave cylinder.. i may get one if bleeding doesnt work.. definitely get one...those internal slaves are such a !#@$% that you should probably replace it while you have it out, just to be sure that you aren't gonna have problems with it. i want an ax15 though for my truck, but then i'd have to make my own bellhousing or adapt the ax5 60 degree bellhousing to fit. at least then i'd still have my external slave :P Link to comment Share on other sites More sharing options...
88swampedmj Posted February 20, 2007 Author Share Posted February 20, 2007 haha yea i really don't like internal slaves... its more work when they mess up.. and with my luck ill be doin a clutch/slave cylinder swap soon Link to comment Share on other sites More sharing options...
JeepcoMJ Posted February 20, 2007 Share Posted February 20, 2007 haha yea i really don't like internal slaves... its more work when they mess up.. and with my luck ill be doin a clutch/slave cylinder swap soon well on the bright side, you won't have to do it again for awhile. and if you're smart enough and have a good floor jack you only have to pull the tranny back about 8 inches to access it. you'll need to take the shifter out to do the whole thing, otherwise it'll get stuck in the cab. so if you take it out, remove the shifter, disconnect the 4wd linkage (if you have one), remove the rear driveshaft, disconnect the front one from the axle, get a jack under the tranny and drop the crossmember, then reposition the jack under the middle of the tranny and unbolt it. slide it back a lil bit until you have enough room to access the system, and then proceed to swap out your clutch and slave. had to do this on my truck...otherwise i would have had to cut the brand new exhaust that I made for it. remember to disconnect the vacuum hoses and switches from the wiring.

88swampedmj Posted February 20, 2007 Author Share Posted February 20, 2007 ive replaced the clutch/slave on my 88 mj and yea it wasnt fun thats why iam really hoping i don't have to on this one.. its a 2wd so itll be way easier but still no fun lol Link to comment Share on other sites More sharing options...

I got completely done with the 3.8 conversion on my comanche, and found the clutch was slipping. well i knew i didn't put it in backwards...ended up being that the 3.8 flywheel is 3/8 inch thicker than the 2.8 so i had no dead space between the throwout bearing and the pressure plate. i thought i had accounted for that but apparently not. so i had to do 7 hours worth of work to shave 3/8 of an inch of the back of the throwout bearing and it's plate. then we couldn't get my clutch to bleed...it had dead air in the end of the slave sooo had to fart around with that for awhile. again, at least my slave is external but yea it's no fun in any case.

mjeff87 Posted February 20, 2007 Share Posted February 20, 2007 Hey, at least it isn't an automatic...... We actually removed/installed an AW4 three times this weekend (only the last time with a tranny jack 'cause we were whooped by then). Long story short, if you replace a 2.5L,2WD AW4 with a 4.0L 4WD AW4, make sure you reuse the 2.5L version of the bellhousing and torque converter, and also make sure there's a torque converter seal on the tranny you are installing. :roll: Good times.....

Jeff haha, oh i'll be replacing a 4.0 aw4 here in the next couple weeks. well, unless it's just the torque converter...haven't figured it out yet when you put the xj in gear and rev it it acts like it's in neutral? makes no noise either. idk what that would mean. what do you have to disconnect to swap out that tranny, and is it hard? do you have to adjust anything at all when you do it?

mjeff87 Posted February 20, 2007 Share Posted February 20, 2007 I hate automatics...can't troubleshoot it any more than to say the TC might be bad, or something wrong in the valve body (does it move in any gear?). What's the fluid level/condition? Dropping it is the same as a manual, except with the addition of the shift and kickdown cable and bracket, the tranny oil lines to the radiator, and the TC to flexplate bolts. To access them (on a 4.0L you have to drop the starter to) remove the inspection plate and rotate the engine via the harmonic balancer bolt to access the four bolts one at a time. Once removed, pull the bellhousing bolts and slide the tranny off the dowel pins with the converter still engaged to the tranny. Don't forget also to pull the dipstick tube before dropping. Tranny jack HIGHLY recommended... Jeff Link to comment Share on other sites More sharing options...

Jeff Nope, it doesn't move in any gear. the kid (a friend of my brother's) beat on the thing pretty bad. the xj is in nice shape and i paid 1200 for it with the intention of reselling it. what happened is he was driving it then all of a sudden it just wouldn't pick up anymore, then it just let go and stopped shifting or anything. from what i gather, the shifter handle still works right, so it "should" shift into gears. kinda seems to me like a clutch slipping or completely dead on a manual...so i'm thinking probably the torque converter? I have no idea how a torque converter actually works as I've only ever driven manual vehicles (gas mileage and burnouts :P) Link to comment Share on other sites More sharing options...

88swampedmj Posted February 21, 2007 Author Share Posted February 21, 2007 oh i noticed my clutch master cylinder isnt low.. so it either has air in the system.. or is messed up.. or its the slave.. the petal just goes to the floor now with no resistance.. even though the master cylinder is full Link to comment Share on other sites More sharing options...
88swampedmj Posted February 21, 2007 Author Share Posted February 21, 2007 could it be the clutch master cylinder? or possibly the clutch relsease fork? Link to comment Share on other sites More sharing options...
JeepcoMJ Posted February 21, 2007 Share Posted February 21, 2007 it's either air in the line, or a bad master or slave. can't be leaking cause it's still full. try and bleed it, and if that doesn't work, check out what the symptoms of a bad master are. I'm gonna go out on a limb and say that it's probably time to buy that kit you were talking about. how many miles are on the clutch? and the slave?

88swampedmj Posted February 21, 2007 Author Share Posted February 21, 2007 iam not sure i just got the truck.. iam guessin a few though the guy said he had it for 5 years.. and in the book with all the work done to it i didnt see anything for tranny/clutch work.. so its prolly just old.. i may get that kit and swap everything at once.. just so its new.. its my dd now Link to comment Share on other sites More sharing options...
87manche Posted February 21, 2007 Share Posted February 21, 2007 mine did that precise thing when the master went bad. Master was leaking past the seal in the bore, wouldn't hold pressure. Link to comment Share on other sites More sharing options...
