Seeing your diagnosing photo, I think mine might need changing. Its not that bad but there is starting to be a little fluid there every once in a while. I wipe it up about once a week when I'm home. I also had to bleed my clutch before I left, the res was pretty low. Guess I'll have this waiting on me when I get home, but does an AX-15 and AX-5 use the same M/C? I'm swapping engine/trans when I get back.

Yes, they are the same regardless of 2.5L/AX-5 or 4.0L/AX-15 AFAIK.

Check www.rockauto.com for the best pricing, I usually get them for around $50 including shipping.

If you're losing clutch fluid, you'll see it somewhere.

Look at the under dash pic I posted in post #3 of this thread. Also check around the plastic reservoir & where the master bolts up to the firewall. If there is no signs of fluid loss anywhere around the master, it's time to suspect the slave cylinder.

To check the slave, get under the Jeep & look around the bellhousing area for signs of wetness. Due to the nature of Jeeps to leak oil, the clutch fluid may not look like you expect it to. You might think you're just leaking oil. As an experiement, pour some freash brake fluid on your finger tips. Feel how it kind of feels warm? Now clean your hands & feel around the bellhousing. Does any of that oil residue make your fingers feel warm like the brake fluid? If so you found your leak. Get ready to yank the tranny out.

I am rebuilding a 87 and it was missing the clutch master cylinder. I bough a new one which has the thread in fitting. The problem is, my tranny is a NV3550 with external slave and has quick disconnect. I have a line from an S10 with NV3550 so the slave end works but the Master end is also set up for a quick disconnect. Is there a place to buy the right line or should I try compression fittings to adapt to the Master?

Thanks

I just swapped my master cyl in an 89 4 banger and thought I might post of some of the little hiccups I ran in to, in no particular order:
1. It is WAY easier to get the pedal reattached to the push rod part BEFORE the m/c is actually bolted to the firewall.
2. in an 89 2.5, the bleeder is on the passenger side of the bell housing.
3. I had to soak the fitting in PB blaster for about 2 hours before I could get it out of the m/c without rounding it off. In my car it was the threaded type.
4. Definitely was a good idea to remove the master cyl before bleeding/flushing the whole thing. it had all kinds of junk in it I am glad did not get run through the slave.

My clutch squeaks like an old spring mattress. Can you tell me what this might be and what the fix is.....sounds like something needs lubing????

The sound is whether running, in gear, off, etc....whenever the clutch is push (in and out) every head turns....sucks.

Sounds like the Master Cyclinder.. mine has been doing that and recently the pedal started refusing to retract after pressing (making it very hard to shift)

I'm about to use replace both Master and Slave and this thread will be my guide

[girliejeepers]

Replaced our slave and master last night. Trying to bleed the system but there is absolutely no pressure on the pedal. We pumped it for 30 min, still nothing?

Is it a '87-93 style internal, or a '94-'95 external style?
