My clutch issue - Page 2 - ZR-1 Net Registry Forums

I cleaned the bolts and they felt good, no off axis movement, endplay or binding. The length might be the thing though I will check that out.

When I was cleaning the c-beam I noticed that the center cross trusses braces were bent. I looked at my 1984 c-beam and it didnt have the bends. Is this normal or is it distorded?

Holy **** Dave. I'd have to say that happened in the accident. I know it wasn't like that when they changed the clutch. Possibly the reason the other damage occured also although I know you had mentioned noise before, but dude, you drove that car over 10,000 miles. Think about it. Can you go back on your insurance company for repairs??

Ya I could see how the wrinkle in the c-beam was caused by the rear end collision enven thought there was no chasis damage. But for the life of me I cant see how the accident caused the bolts to come loose and damage the throw out bearing. Also the strange noise stayed the same before and after the accident. I will say one thing though you old car is cleaning up nice. I hired a guy to help me with the clean up, I pull a part off and he cleans it so far its working great. I'll give you a call later though.

I believe that the C-Beam on all ZR-1 have what appears to be bends in two of the diagonal portions. The C-Beams that I removed on all three ZR-1's that I worked on this fall were like that.

Here is the best picture that I could find:

Before you decide that your C-Beam has been damaged, lets get some more examples to compare to.

I will got check the ZR-1 on my lift right now and report what I find. Don't panic.

I just checked the C-Beam on my 1993 ZR-1. The two "truss" sections that you highlighted in your picture are "bent" on my car. I am sure the C-Beam in your picture is in proper condition.

I could not take a picture of the bends with the C-Beam on the car because the exhaust is in the way.

I remember seeing a C-Beam for sale at Corvettes at Carlisle last August and it had the bends also.

Well maybe that beam could have been like that after all. I would have to say the installation may have been faulty, but I'm glad the car got you home and there isn't to much damage. I'm surprized at the crank bolts though. I don't think I've ever seen any come loose on anything before. I'm sure they have though. I didn't use the longer bolts in the pressure plate/flywheel, so if those make you uncomfortable, get the longer ones from Randy. I got the flywheel from Ultra Rev, they have the replacement facing for them too if you are going to replace it.

I put a Needle Pilot Bearing in my 90, but i've used both, often. Your choice...either or, not a big deal one way or the other.
