Can\'t get clutch to disengage

I just put in a scout T-19. I used a bellhousing off of a t-176 with a new clutch for a 77 cj with a 4 speed. The throw out bearing and arm are the ones used for the t-176 clutch. I am using a wilwood m/c and slave and I can't get the clutch to disengage. The slave cylinder pushes the throwout arm a good four inches. I think that I have the wrong throw out bearing and arm, but I would like any other ideas before I tear it apart, and try a different one.

Re: Can\'t get clutch to disengage

i just went thru a similar problem with my scrambler. i "thought" that the slave was pushing the throw-out arm far enough...but it wasn't. climb under the jeep and manualls (with your hand) make the throw-out arm push against the pressure plate fingers. you will not be able to move the fingers and it will feel like it hits solidly. there should be a 1/8" gap between the end of your push-rod and where it contacts the throw-out arm. my problem was i had a 3/4" gap and it would not disengage and allow the clutch to slip. i ended up lengthening my pushrod and all is happy now! let me know if you need any further assistance.

btw, what master cylinder are you using?

Re: Can\'t get clutch to disengage

jeepnmatt, thanks for the reply. The distance is about 1/8", I have even adjusted it far enough in so that the throw out bearing would "race". The master cylinder is a 3/4" wilwood unit that I bought at daymotorsports.

Re: Can\'t get clutch to disengage

Years ago, after an engine rebuild on my '58 MGA, I couldn't get the clutch to disengage. Everything seemed to be right, but the clutch just would not disengage. It turned out that I had put the clutch disc in backwards and the springs, which are off center in the clutch disc, got caught between the flywheel bolt heads.

On an MGA, the tranny comes out through the passenger compartment. When you have to take one of those back apart for something like this, you never forget.

Re: Can\'t get clutch to disengage

CJ7 taz-I didnt know you could put one in backwards. or was that just on that type of clutch? I have replaced several clutches, so maybe I just got lucky before?

Re: Can\'t get clutch to disengage

well, I just went out and tried to manually pull the throw out bearing lever back and it won't disengage at all. For those of you running a t-18 with an AMC engine what did you use for a clutch, throw out bearing and lever?

Re: Can\'t get clutch to disengage

I used a stock replacement Jeep clutch, pressure plate and throwout bearing on my T18 conversion. I used my original T150 bellhousing, it has the standard clutch fork and linkage, not the hydraulic stuff. I didn't have a problem with it.

Sorry I can't help but you asked what others with T18s used.

Re: Can\'t get clutch to disengage

I have a t18 in my CJ, and i used a centerforce II pressure plate with a stock disc (turned the right way), and throw out bearing. The only problem I encountered was with the fork. I needed to notch out a section of the clutch fork in order to clear a mounting stud for my t18. If this is not notched the clutch won't work.

Re: Can\'t get clutch to disengage

well, I pulled the tranny again and the clutch was in the right way, and everything else looked fine. Now I am stumped. Did you guys use a 3 finger or diaphram setup? Would it matter either way?
