joshmillslane Posted December 13, 2007 Share Posted December 13, 2007 So, I'm trying to diagnose some clutch issues I'm having with my 86. It's the 2.8 w/ ax5. The previous owner says it has a new master and slave cylinders and the master looks new - can't see the slave obviously. I've been intermittantly losing my clutch. It normally engages mid pedal, but sometimes, the pedal goes soft and it'll engage right off the floor. I pump it a few times, and it's back to normal. I'd say this hapens about 5% of the time. Maybe once everytime I drive it. The other strange thing is when I first get it rolling when it's been sitting and cold, the clutch is grabby as hell. It wants to engage immediately which bogs the motor almost to stall. I jam the pedal back down, get some RPMs, try to slip it again with the same result. It bounces the hell out of the truck. It only does this on the first start when it's cold. After driving a bit, it's fine. I ordered a new slave cyl, clutch, throwout bearing, and rear main seal just in case. If it is the slave cyl, I'll just hit em all at once. Thanks in advance. Link to comment Share on other sites More sharing options...
Oizarod115 Posted December 13, 2007 Share Posted December 13, 2007 doesn't sound like a master cyl, when mine went out i had clutch one day and nothin the next, no leakin or anything. just barely anything not enough to drive then the next day completely gone.

Some body told me it was my fly wheel being warped. I don't know but my car sounds alot like what your truck is doing. banging really hard when you let out of the clutch.

joshmillslane Posted December 13, 2007 Author Share Posted December 13, 2007 I'm not sure about a bearing issue. normally you can hear those when they start to go, right? A difference in sounds with the pedal in or out while in neutral? Anyway, it's just strange it only grabs when it's cold. Link to comment Share on other sites More sharing options...

It's just the violent way it engages Link to comment Share on other sites More sharing options...
Geonovast Posted December 13, 2007 Share Posted December 13, 2007 You should be able to see the slave. 86 was an external slave setup. Also, you said you ordered a new slave and a new throwout bearing? If it was an internal slave, those two would be one piece. Just FYI. Sounds to me like something's leaking somewhere. Mine does something similiar, so I've gotten into the habit of just leaving it in neutral if I have to have the clutch pushed in for more than a few seconds. I've just now started to see some fluid coming from the bellhousing, although the level in the master isn't getting any lower. Check above your fusebox for fluid. I had an 89 XJ that had the master go out in it right before I bought it, and it soaked the fuse box. That truck had a lot of electrical problems when we finally got rid of it.

joshmillslane Posted December 13, 2007 Author Share Posted December 13, 2007 That's good info. Thanks! I thought the ax5s were internal - it's hard to find accurate info on the intraweb - especially with everyone modding the hell out of these things. Just a thought - could an improperly bled system cause the problems I am having? Thanks! Link to comment Share on other sites More sharing options...

It might just need bled out because it has some air in the system. Link to comment Share on other sites More sharing options...
carnuck Posted December 15, 2007 Share Posted December 15, 2007 Not all AX5s are external. I have seen 3 so far that were internal (my son has one) Link to comment Share on other sites More sharing options...
Geonovast Posted December 15, 2007 Share Posted December 15, 2007 Not all Ax-5 are internal, same with the Ax-15, and if I'm not mistaken (which I may be) the Ba 10/5 has external kits. My 91 with an Ax-4 has an internal, although I'm saying goodbye to that when the Converted Ax-5 goes in, which is out of an 86 XJ. If for some strange reason yours is internal, I would switch it over to external while you've got everything apart. Link to comment Share on other sites More sharing options...

I have never heard or seen external kits for the Ba 10/5, at lease here in the states. I too can be mistaken if there any pic's of this contraption it would be cool... at lease dishonorable mention :rotf: Link to comment Share on other sites More sharing options...
partsmj Posted December 16, 2007 Share Posted December 16, 2007 I remember way back, when they used to see these in the shop. The way to bleed the clutch cylinders, is to unbolt the slave from the bellhousing and find a way to compress the rod that fits in the fork. A socket and a big vice grip is the way to go. One pump at a time and always fill the reservoir because it runs out quick. Hope this helps. Any questions let me know. Link to comment Share on other sites More sharing options...
joshmillslane Posted December 16, 2007 Author Share Posted December 16, 2007 Why unbolt it? I tried bleeding it without removing it. I did flush the system a few times (lol) but it didn't do anything for the pedal feel, and I still lose the clutch every now and then. Link to comment Share on other sites More sharing options...
partsmj Posted December 16, 2007 Share Posted December 16, 2007 You must compress the rod into the cylinder. I don't know why, but I do remember it was the only way the mechanics could bleed them. The cylinder had to be removed. Maybe use a c clamp to compress the rod into the cylinder. Good luck. Link to comment Share on other sites More sharing options...

Internal or external depends on the year, not the tranny. All the BA10/5s were internal. Link to comment Share on other sites More sharing options...
rustywrangler Posted December 19, 2007 Share Posted December 19, 2007 All BA-10/5's are internal Both the AX-5 and AX-15 are internal slaves up untill the end of 1993. Then they both went external. Link to comment Share on other sites More sharing options...
carnuck Posted December 19, 2007 Share Posted December 19, 2007 I have 3 AX-5s here that disagree! (one from my '86 MJ, one from the '85 XJ 2dr I'm parting and one in the '85 XJ my son just bought back from the guy I sold it to) Link to comment Share on other sites More sharing options...
Pete M Posted December 19, 2007 Share Posted December 19, 2007 Early AX-5s seem to have been external. Got one on my 86 MJ. Link to comment Share on other sites More sharing options...
