I think I am going to bite the bullet and collect the parts needed to swap my internal slave for an external slave setup for my '93 XJ 4.0. I've been having problems with the internal slave sucking air and not releasing as it should. Been dealing with this about a year and am tired of not trusting the jeep to get me there and back. Contemplating yanking out everything and starting new with the external slave and perhaps a centerforce clutch set up.

The question I have is what parts do I need? I found an AX-15 external slave bellhousing ('94+) for $100 in the local bone yard-
comes with the release bearing fork. Any other hardware? Can I reuse my earlier CPS in the newer bellhousing?

I'll know I'll need a slave cyl for it. I've heard that the '94+ clutch hydraulics are a one piece system- or at least sold as one by the dealer. If I bought a slave, could it be used with my current master cyl- I just bought it for $250 at the dealer <IMG SRC="smilies/frown.gif" border="0"> . How about the hose? If the slave and master can work together could I pick up the hose from the junk yard? Do the '94+ systems have the same o-ring and rollpin set up as the '93- does?

If anyone done this and can point me in the right direction I would appreciate it. I am going to the junkyard tomorrow to ferret out
the parts.

Thanks

Johann

Looks like you got hosed on the slave cylinder. I got a 95 YJ master/slave cylinder for about $100 and it includes the plastic hose.

Thanks Insayn, I figure I'll be picking that up at the dealer new week once I have the bone yard parts.

Have a good weekend <IMG SRC="smilies/beer.gif" border="0"> <IMG SRC="smilies/beer.gif" border="0">

We just did one, but I didn't pay that much attention to what we did. I just remember working my ass off R&R'ing the trans and t'case wtihout a floor jack.

I know we had the slave, bellhousing, and the internal lever. I don't remember having to change anything else.

Johann -

You can convert to an external-slave clutch system, but it's gonna take a bunch of parts. You'll want that bellhousing you found (your CPS should bolt up, but check), plus the throwour bearing, fork, boot, retainer spring, and pivot ball. You'll also need the external slave plus the connecting hose AND the master cylinder that goes with them. The hose end is not compatible with your original master cyl. When you go to install the new master, you'll notice that the hole in the pushrod (that the pedal goes into) needs to be enlarged to fit.

The last thing you need is the bearing retainer from a later-model AX15 tranny. The best bet is to get one off a dead tranny, since they're real pricy, new. The old and new retainers are slightly different, though I've been told it's possible to modify your older one to work with the new throwout bearing. Don't know the details here, but hopefully it'll be obivous when you look at all the parts.

EDIT: Hmm, just noticed you said "XJ". Not sure if my advice re: the master cyl will apply, in that case. Look and see...

Good luck,
Chris

Thanks cwate,

Sounds like you have been down this road before. I'm glad I got your post before my trip to the yard.

A couple questions if possible. Is the bearing retainer you mentioned go on the fork for the throwout bearing or is it between the bell and the tranny?

Also can you tell me where the boot goes too?
I'm going to have to describe these to the yard man and I don't want to sound like an idiot (any more than usual)

I was given this link AX-15 tech on an XJ BB that mentions the difference in pilot bushings but I guess I stick with the one that goes with my current tranny.

Thanks for your help

I hear ya about the R&R of the tranny/tcase, not looking forward to it.

I think I'm going to splurge and get a good jack and tranny adapter. If I'm going to save money by doing this myself it's got to go somewhere!

By chance do you remember what year you were swapping- to and from? That info might come in handy.

Thanks,


Johann

Advanced Adaptors can make you hose with the proper ends for around $30. You DO NOT have to buy the hole set up. Any Crown dealer or distributor can sell you just the slave unit without the MC. I know No Excusses in NJ can get them separetly. HTH

Sort of <IMG SRC="smilies/smile.gif" border="0">. I looked long and hard at this option before deciding it was too much of a PITA and just replacing the internal slave. Part of that decision was also the awareness that my 258 was going to be history soon. The 5.0L that's replaced it has an NP435 bolted to it, and a factory external-slave clutch system courtesy of Ford...

Is the bearing retainer you mentioned go on the fork for the throwout bearing or is it between the bell and the tranny?
It's part of the tranny, which is why it might be hard to get. It bolts onto the front of the tranny, and is what the throwout bearing slides along as you move the clutch in and out. Sort of tubular-shaped.

Also can you tell me where the boot goes too?
Oh, the fork book. Rubber thingy that goes between the fork and hole in the bellhousing that the fork goes through. Stops water & crap from getting in there.

Good luck,
Chris

My info comes from my swap of a 4.0l and a '97 ax-15. I was lucky that it already had the external slave and all needed parts. I specifically looked for one newer then a '94. I did have to explore ways to adapt the MC, mount and t-case linkage.
