Idle problem fixed - throttle cable was stuck out of its housing.

Clutch still f*cked up - no change. With the bell housing that allows easy adjustment, almost on the fly - it would go from fine to horrible - more on the horrible side.

So either both of the intermediate discs are bad - or it's something else.

Are you getting full travel of the release arm? Can you freely move all of the parts with your fingers with the release arm pulled back? Are the intermediate plate adjusters all pulled fully to the rear?

from a pure physics stand point the clutch will not disengage if there is pressure between the flywheel , the clutch disk and the pressure (or intermidiate plate and second disk). There has to be a condition where the slave cylinder is not pushing the pressure plate far enough or the intermidiate plate is hanging up. When you are under the car how far does the release arm move? How far does the slave cylinder move when you press the pedal? Maybe see if the distance the slave cylinder moves is the same when it is free from the release arm as when it is connected. (release arm bending?).

You'll launch the piston if you try that.

I just spoke with Dennis. He just got into his clutch pack. It seems one of the bolts was missing from his guide tube (it was on his workbench). D'oh!

Yeah and I regret that I HAD TO FIRE THE MECHAIC that did that. The funny thing is I did Stans clutch rite after mine and his is woking fine. After he left I found this bolt and called him to say we had a extra bolt left over and I put it in my tool box.Who woulda thunk! It sure wasn't me duh!

I realize this – what makes it hard to find is how intermittent it is. What would be “wrong” causing it to release fine one minute – hang up the next. This is the baffling part of the issue. Something must be slipping / sliding around causing the release distance to move.

Measuring the travel distance is hard enough, much less with the car running and a pressure plate spinning inches from your face. It’s so random when it works / doesn’t work I’m having a hard time determining if the release arm is moving the full distance when it’s dragging.

What parts? The discs? I don’t know since I cannot exactly reach them with my fingers to try and turn them. With the release arm pulled back, turning the motor by hand does not move the clutch discs.

That is where I set them (on the new/used disc) the first time around – didn’t work at all. So then what I did was (using the bellhousing with the hole in it) with my helper pushing in the clutch pedal I moved the t-adjusters just a tad bit forward to increase the space between the rear most disc and the disc on the intermediate disc. I could still see a gap between the intermediate disc and the front friction disc. After this adjustment, the clutch was working 100% perfect – for about 2 miles. Then it stopped disengaging totally. I parked the car after this, didn’t have time to try anything else.

I’m going to install a new release bearing tomorrow. I can push the release arm about ½ inch back and forth while everything is installed (bellhousing / slave removed). This is the slip I posted in the video above. Who knows, maybe this slop is causing the problem. I’ve replaced everything else up to this point (except the pressure plate – have a spare one of those on had to).

Did you set the T-adjusters all the way out?

hacker-pschorr

Please explain "all the way out" since either I'm missing something or that isn't working either. I tried moving them all the way forward / backward in the middle etc...

They pull out toward the pressure plate. Move them all the way out....but it looks like you did that.....also....errrrr.....did you remove the shims? Just kidding.

Install a "wisker switch" to monitor the release arm movement. Wire it to a simple incandesent bulb so if the release arm moves far enought to release the clutch the bulb will light. The next time the problem surfaces you will know what system to look at.

Am I to take from all the various threads that when installing a GTS pressure plate, one should replace ALL parts with the updated parts (in my case, for installation into a 90 GT) to avoid issues?

- release bearing
- release arm
- guide tube
- disc (of course)

Thanks.

Last night, limped the car over to Tim Murphy's house to take out my clutch.....again. This time armed with a new release bearing & guide tube. These were installed with my original pressure plate, intermediate disc and clutch discs.

Since day one of this project, I've been looking for something that suddenly broke since it was shifting fine - then all of a sudden let go. Well, as you can see in the picture, a few pieces in the release bearing broke.

So far, all three test drives it's shifting 100% perfect. Even before when it would shift, it was never this smooth. Wish me luck, I give up if this is not the long term fix for my clutch.

Pictures speak louder than words:

All that friggen effort for that little turd! Damn!

Looks like you stomped your clutch gremlin -- way to go!
