clutch

[corvette66]

So i just got my OD unit together. Time to put the trani back in.
Inside the bell hsg. right where the clutch fork comes in, should the bearing and fork be loose? Mine is just hang'n there. Maybe it came loose when i removed the trani. So should it be hang'n loose, or does the bearing clip into the pressure plate? Just dosen't seem right that it is just hang'n there.

When the clutch is pressed into the floor, it pushes that rod forward that moves the clutch fork and bearing into the pressure plate. Seems to me like the fork or bearing should be stiff, or hooked onto something. The shop manual shows nothing. So just wondering. Don't want to run into a problem once the trani is in.

appreciate any help thanx, dan

Dan -
It's been a long time since I've had the pleasure of removing and installing a transmission so might want to wait for another reply from someone who has done this more recently in order to verify this.
To the best of my rapidly failing memory, the throwout bearing rides on the transmission input shaft up against the pressure plate which will hold the bearing and clutch fork in place. Once you install the transmission correctly with the shaft through the bearing, nothing should be "just hang'n there".
Did you remove/replace the clutch also? If so you will probably need a clutch alignment tool.
While you have this much apart, I would advise to install a new throwout bearing. Easy and cheap to do now.

hmmm

Well i just got under there and put the trani in. Like i figured something would have to go wrong. I have no clutch pressure. The clutch will go to the floor with very little effort. Kind of like it is just hooked to a weak spring, you could press my clutch to the floor with your pinky finger. It is full of fluid. I was going to bleed the line, but i see no point in doing that because I did not touch any of the clutch parts. All i did was remove the trani, then i put it back in. I left the bell hsg. alone. The spline on the trani slid right into the bearing and right in the motor. bolted right in with no problem.
???????????????????????????????????????????????????????

ARRRGGGGG!!!!!!

update

The clutch fork has tangs that will slip over a ball type bolt. Holds the fork in place I guess. The fork tangs will not stay clipped to the ball. Do these types of things go bad?

Clutch fork tangs

The clutch fork tangs should slide behind the ball end of the stud and hold the fork snug against the stud. If you 'engaged' the clutch with the transmission removed, the tangs likely came off the stud and the fork no longer aligns with the stud. Or the tangs broke off. To re-connect the tangs, pull the fork out (toward the driver's side) about 3/4" then push it inward again, forcing the tangs behind the ball. You may have to remove the trans again to assure engagement (inspect to see if the tangs are intact). My experience is with older Chevy/Camaro's so I'm not sure what a Corvette has for tangs and how they are attached, but the Chevy/Camaro has the tangs riveted to the fork. If broken, replace the fork (not a lot of $).
Hope this helps

Well here is what I have done so far: First I removed the slave cylinder, and bled it. Also did a check to see if it was working right. It is. Then I looked into the side of the bell hsg with a flashlight, the fork is real loose. I pulled on it, wiggled it back and fourth for a while. Got the tangs to hook on the ball. But what happens..... when i get it all back together adn press the clutch it pops the fork tangs back off the ball. So I am thinking maybe the tangs are weak. And the tangs are rivited to the side of the fork. So maybe if i get a new fork it will fix my problem. I imagine the fork tangs should hold the fork in place pretty tightly.. right??? I can pull the fork tangs on and off the ball stud pretty easily. Probably shouldn't be that easy.

thanx

The tangs only hold the fork loosely. The actuator rod (from the slave) should hold the fork against the ball, the other end of the fork held by the throw-out bearing. Once clutch pressure is applied, the tangs do nothing.
Is the throw-out bearing properly seated between the two fork prongs and up against the clutch fingers (with the transmission input shaft through the throw-out bearing)?

Sorry, i was out of town the past few days.

Well I got it going. The bearing was in backwards:bash
