Clutch/slave cylnder

My clutch has serious problems. Here is the problem, I fill the reservoir up with fluid before I go. Pump the clutch some and it engages/ disengages just fine. After a couple of miles it stops engaging all the wayand you have to pump the petal a little. Until a couple more mile when the petal has no effect. I can drive it but I don't like to without a clutch. So I am wondering what it could be. This is my 3rd transmision. I bought it with a bad tranny (I was aware and Jeep was very cheap). I had someone put one in a couple months later. It ran fine for a yeAR TILL THESE SAME PROBLEMS started happening. The synchronizer was not put in correctllyand the gears were chewed up so I was told that I had to put in another, now on my 3rd (still an Ax-15) and these problems start almost a year later. It was worked on in October of 01. The slave cylnder was been replaced. So far all I have done is bleed the clutch and it worked fine, for like 1 mile. I didn't know if you had any ideas of what the problem could be. Any suggestions would be great, I just want to drive my Jeep!

Just so ya know
I have an internal slave cylnder
There is fluid on the bottom of the bellhousing
After it stops working there is very little fluid in reservoir. Thanks for any help

Re: Clutch/slave cylnder

The actuating part of your clutch is leaking. Top off the resivoir and have someone pump the clutch for you. Watch from the master cylinder all the way down the line to the slave. From what you are describing I would guess that either your slave cylinder or the the line going to it is leaking. Make sure to check the line wherever there is a bend and when it comes close to other pieces (frame rail)they move around quite a bit when driving. Also check the connection to the slave. If you have a warrenty on the slave use it, if not most cylinders can be rebuilt. Clean all of it with a good degreaser first before you inspect. Good luck.

Re: Clutch/slave cylnder

if your having to constantly ad fluid to teh master cylinder the above post is correct!

if its not leaking fluid, but still not holdng pressure its possible for the master to be leaking internally, that is not actually dripping fluid, but not able to build pressure like it should.

rebuild or replace the master cylinder in that case.

The slave is bad. They go bad, and it sucks, because they are a PITA to replace. Try to get an external slave off a newer Jeep, or the older ones with the GM engine. I think they are like $80 new, and they will work with your master.

Re: Clutch/slave cylnder

From my experience, I have gone through 4 master and 2 slave cylinders in 2 years.

The first slave cylinder was not replaced correcly. SO I thought it was the Master several times and replaced it 2 times.

Then the slave that was originally put in wrong went out, so I had that replaced again (correcly)

Now I bought a master sylinder from Autozone and I just swap them out every 6 months (easy 10 min job)

I was told also that if you can find DOT5 fluid works best with the foreing Master cylinders they sell. The DOT3 ruins them in time.

So in a nutt shell, THE CLUTCH system of YJ's SUCKS big balls. Go external if you can. I know I will as soon as I find parts to do the job.

Re: Clutch/slave cylnder

i had a similar problem with my 91 yj. turns out that mine was leaking from a pinhole in the line running to the slave. there was no rubber grommet to keep the line from moving around, and it rubbed on the opening of the bellhousing enough times to cause a leak to develop. it would leak inside of the bellhousing and drip out the bottom. after replacing the line, i wrapped the line up with fuel hose for protection, and have not had any trouble since. i would go underneath with a flashlight and goggles while someone else pumps the pedal, and see if you can pinpoint the leak. the goggles are a must, as brake fluid in the eyes tends to sting.

Re: Clutch/slave cylnder

Thanks guys, hopefully I can change over to an external system. And yes, I have come to the conclusion that my hydrolic clutch really does suck. Oh well, its not like I have ever had the whole Jeep running at once. Sometimes I dream about a Jeep that never breaks down and gets decent mileage. BUt any way thanks for the help, looks like I 'll be dropin the tranny.
