I have a problem not relating to Corvettes,but the car is a Chevy. I have a '57 Bel Aire project car besides my 80 Vette. The 57 has been stored for about a year. When I started it to show it to a prospective buyer,the clutch would not disengage.I checked the linkage and everything from the pedal to the clutch assembly moves,but the clutch does not disengage.---Any help would be appreciated, Thanks , Dave80

 

how is the cluch fork,,,,,might have slipt of of the throughout bering..it is simple set up....

the cluch fork pushes the throughout bering thus pushing on the pressure plate and disengageing the cluch.let go and the cluch engages...might have a rusted input shaft and not leting the cluch slide back and forth.might have to break in half and free it up...could try some rust penitrater.but you will have to make shure you clean the cluch real good good luck

 

Can you push the pedle to the floor? If so, check the linkage. There is a piece that connects to the frame and the block. A broken engine mount can allow the engine to rock and this part of the linkage to slip off of the ball type pivots. Odd though, that after sitting for a year, it suddenly doesn't work. If the pedal won't move the throwout bearing could be siezed on the pilot shaft. Never heard of this happening though, but is possible.
One other thing, the guts may have been pushed out of the throwout bearing, allowing the clutch fork to move but not put pressure on the pressure plate to disengauge the clutch. (I've seen this happen)
Well, there's my best shot!

 

Thanks for the advice,my clutch now disengages.

 

So what did you do?
