No clutch

I have a 87 Jeep Wrangler with a AX-15 trans. I have replaced the clutch, pressure plate, pilot sleeve, slave cylinder, master slave cylinder, bleeded the system and still have no clutch. The clutch pedal feels fine until you start the engine and then it feels soft. I that taken everything apart and re-assembeled but still no clutch. Does anyone know how to fix this? It is driving me nuts! My mechanic friend said he saw a similiar thing happen to him on Ford truck and it was due to firewall flexing. Ford makes a kit to re-enforce the firewall.

Firewall or flywheel? If you leave it in gear and try to start it (brakes on!), what happens? I did have a yj where the pedal itself was broken but in a non-obvious way, and it broke so it was holding down just enough to be slipping. Might be worth looking.

I guess it could also be the clutch fork (or whatever it is called) or the pivot bushing it rides on. I haven't seen those wear to a point that the clutch doesn't work at all, but that doesn't mean it can't happen.

If I leave it in gear and start, it moves. What was your problem with the clutch petal? Did you repalce the petal or the petal bushing?

That's good, at least it means the clutch is grabbing at least a little.

The bushing broke on mine, leaving too much left to right play, which wedged the plunger shaft (possibly making up terms, but that's what I would call it). That was many moons ago, so I don't remember how I fixed it, but if I did, it must have been obvious how to go about it :-)

when you bled the system, were you getting good fluid pressure out of the bleeder?

Yes, I got good fluid pressure with no air bubbles. Could the new slave cylinder be defective?

thats internal slave, right?

are you sure you got the slave seated all the way down with the little keeper tabs thing secured (im not sure if its the same on the ax15, but on the 5 theres little strap things to hold it compressed until you get it installed.

i would think if you've got good pressure at the bleeder, itd have to be a trans side thing (as opposed to hydraulics). but im no expert
