Well I got my jeep setup for hydrolic clutch. It is a T-90 tranny and buick 4.1L V6. When I first was driving the jeep the setup made no noise. I since had to take the tranny off and balance flywheel. I put everything back. At first I noticed it was hard using the clutch. It would grab and stick and sometimes just let go. I looked underneath and noticed that the fork was off the pivot. I knocked it back on and titghtned the pushrod to the fork just enough to keep it from rattling. The clutch works fine. It engages and disengages just fine, but when i am driving there is a high pitch metallic whine. I will push down on the pedal a little and it will cease. Let go of the pedal and it comes back. I tightend the pushrod a little to try andeliminate the squeal, but it does not work.It seems louder at idel, but I could be wrong, because I have glasspacks and they override alot of sounds. I believe it is the throwout bearing, but it is brand new. I am thinking maybe i bent the hold down tangs on the fork and it is the fork rubbing on the pivot. I looked into the bellhousing and everything seems kosher.I did not grease up the pivot point where the fork contact the bellhousing nipple. Is there any other things to look at? How long will a throwout bearing last like this? Will it maybe cure itself? I spend a little while tonight banging the fork and twisting it to see if realigns itself. When I reinstalled the tranny and clutch I did align everything up with an old T90 input shaft. I am trying to avoid pulling everything part again. And we have a big trip with my club this weekend. My friend said it might be that I did not lube the bearing retainer.
Thanks for the help

I haven't looked at with the jeep running. My headers are outside frame typpe and they really heat my face up. I don't have the borg & beck I have the diaphram type. The borg and beck are the three finger type. I have the multiple finger clutch. I know that with pressure the noise goes away, but i don't know how much pressure is good. Everything seems to be ok looking inside.

Jaffer,
My setup for the hydrolic clutch is different from yours. I had to use a pull type slave cylinder. I do not have a return spring for the slave, but i do not think it will be hard to put on on. I was going to put one on my pedal, because there is one there, but i guess i will put one in both areas. The fork is correct and to is the bearing. This setup worked fine when i first installed it, but it started whining after i pulled the tranny from the jeep and reinstalled it. I did not do anything different. Only thing that was wrong was that the fork was off the pivot and i tried to drive it, and maybe i bent it. How much pressure can i put on the fork? I tried to put some more pressure on the fork, by turning the adjustment screws on the slave cylinder rod to the fork. I am thinking about trying to put pressure on it, because when i do press the pedal down it stops, i am just dont' want to burn out the clutch.
Thanks

Jaffer,
I got the pival ball in place. The little fork that holds the clutch fork to the pivot ball seems OK. It is on the fork and seems in fine shape I did adjust the slave onto the fork so that there is not rattle. Maybe i should loosen it and put a spring there and get rid of the rattle. When i get home i will disconnet the slave from the fork and see if the whine is still there.
Thank you for the help

Jaffer and Dirtrod,
I got the whine to stop. I loosened the slave pushrod so that the fork can wiggle. It is gone, now i can hear the fork rattling while driving, so i have to tweak it to be quiet. I am going to put a spring down there to try to keep it quiet also. Thanks for the help
