Clutch install problem 2000 Corvette
I am installing a LS6 clutch in a 2000 Corvette. I am using a 2001 Torque Tube with 2001 Z06 throwout bearing. I get the tube withing 1/4" of the bell housing and it the throwout bearing runs out of travel. The distance from the flexplate to the bell housing is 4 3/4" the distance from the face of the clutch support to hte face of the torque tube with the throwout bearing compressed is 5". I need help understanding if I need to adjust something or I am missing something. Is the space fo hte throwout bearing the same for all throwout bearings? Do I need to adjust the fingers on the clutch? The clutch was in the car before but I did not install it so I don't know it if had issues before or not. I did buy a new throwout bearing but do not see any difference in the spacer. Please let me know what I am missing.

Be sure that you have the clutch towards the proper side of the flywheel.
Should be marked "towards fly wheel".
Make certain that the alignment pins/ lugs (at the T/tube area) are "spot on" aligned and are not causing the problem of not pulling in all the way.

Before you get too far,, Answer the following questions and Make sure the following:
Are you installing the differential/trans and TT as ONE ASSEMBLY?
Have you tried to slide it together WITHOUT the slave cylinder to prove the theory that you may have a stack up issue preventing bolt up???
Are you sure that the drive train is properly lined up with the bell housing/clutch plate and pilot bearing. If any one of those is not SPOT ON aligned, it can cause.
Here is something that I found that makes drive train assembly MUCH easier. Seperate the torque Tube from the transmission/differential. Install the TT into the clutch/bell/pilot, bolt it up and then reinstall the trans diff assy to the TT.

I have separated the torque tube from the transmission. I pulled the clutch and slid the torque tube in place without the clutch and the throw out bearing on the shaft. The torque tube does connect flush wth the bell housing when the pins are alligned. I have also had the clutch in and when I try to bolt up the TT it gets within about 1/4" from meeting up with the bell housing and stops. I think the thowout bearing has bottomed out before it bolts up. I was able to get the point of the shaft into the pilot bearing in both cases. Is there a difference between 2000 Corvette cluch, throwout bearing and TT and a 2001 Z06, LS6 clutch, throwout bearing? I wanted the 12mm TT so I got a used C5 TT from a 2001 Z06. I did check the clutch and put the flywheel side towards the flywheel. I will double check. Can the fingers be adjusted on the clutch. Reason I changed was I rebuilt the motor and put a 2008 Z06 trans/rear in the car so bought a 12mm TT to go with it. An LS6 clutch had been installed by the previous owner with the original TT. Bought a new throwout bearing for good measure. I wanted to make sure I was not mismatching parts or something else weird was going on.

Are you POSITIVE you have a C5 Throw out bearing and slave cylinder??????
There are C6 slave cylinders and throw out bearings that will NOT fit a C5..
Do you have a C6 slave or bearing by mistake?
Some applications recommend SHIMMING the throw out bearing. In a stock application, YOU DO NOT want to shim it.
Compare the New slave Cylinder/Throw Out Bearing (compressed) stand out distance on the new TT to the same measurements with the old components on the old TT and see if there is a difference.
Something has to be different.

I will check it. It is not a C6 throw out bearing. I bought the throwout bearing from Chevy direct for a C5 and it looks like the one that was in the car. It has a black slider with spring on the outside. I also have C6 TT that came with the rear end and the throwout bearing is green and more of an accordian cover. I will check the compressed distance with the 10mm torque tube and throw out bearing and see if it is the same distance as the 12mm TT and throwout bearing. I agree something has to be different. The engine has been rebuilt with a Callies crank. Could that have moved the flexplate back away from the block? I will try to take picture in the next couple days and post for more conversation.
