Topic: Cultch issues

[DodgeMudder]

Ok, I'm at my witts end trying to figure out my clutch problems and I really need my Jeep this weekend for a trail ride and starting next week to give me a 4x4 for getting through the snow their calling for.

I have a '95 YJ 4cyl, swapped in NV3550, SOA, 34's stock gearing, 8.8, etc.

Back in August I was playing around in a small mud pit people told me I couldn't make it though.  I made it through twice then on the third attempt going the hardest line through, my Jeep stopped, I tried reverse, tried forward again and the tires wouldn't spin.  I got towed out, let it sit till the next day figured the clutch got wet.  I moved it a short distance the next day the clutch was slipping so I just parked it and left it for a week to dry.  I then went and took it for a drive it started out good but it seemed like everytime I shifted it would start slipping worse.  I ended up having to have it towed home after it stopped trying to move at all.  I let it sit for a couple weekes while I was working on other projects, when I noticed a small leak from the bell housing, it was hydralic fluid.  pulled the slave and it was leaking I needed to move the Jeep so I started it in gear w/ the slave still pulled out, it ran beutifully I couldn't force the clutch to slip.  I got a new slave and bolted it in and the Jeep was back to the clutch slipping so bad it wont move.  I decided to pull the slave back out and try it, w/ the slave out it doesn't slip at all.  I couldn't figure out what would cause that, so I pulled the tranny and clutch and everything looks good, put it all back together, w/ a new slave incase the new one was defective, and it's better.  As it sits if I start it in gear I can drive it w/ no problems, if I hit the clutch it starts slipping, the more I use the clutch the worse it gets, if I stop and shut it off for 1/2-1 hour it will start in gear w/ no slippage again.  I just don't know what to do next to try and get this fixed.  I'm going to try a new master cylinder, I don't know if it will work or not, but I don't know what else to try.

Sorry for being so long winded just wanted to make sure I explained whats going on.

TIA

Hmm, I'd suspect the master if you have the same problem with a new slave.  Although, I'd assume that you were able to bleed the system properly each time?

2 things could cause this a collapsed hose or line from the master cylinder to the slave cylinder or no free play and the linkage for the master cylinder. To see if its a hydraulic problem crack the bleeder on the slave cylinder if fluid squirts out under pressure and now there is no slippage, then it means that the fluid is not returning to the master cylinder which goes back to the 2 problems mentioned above

I'd suspect your old slave cylinder could have been damaged and mud or somethin could have made it's way inside... I'd pull off the master and line and see if anything's clogged up.  My auto tech instructor had a similar problem with his brake system.  Cheap fix if that's the case.

Thanks for the replies, I got it fixed and was able to make the wheeling trip Saturday, the new Master did the trick.  I also proceeded to flop it twice once on each side in the same hole right in a row, then barried it in the swamp when I made a bad turn trying to catch up w/ a different group of wheelers on the trail, it took 5 hours to get me out of the woods, using winches and bigger Jeeps, no damage or problems other than one broken 4" strap.
