Trying to diagnose clutch chatter - 1st gear only ??????

[NorCal Cobra]

Thanks for all your suggestions. My slave cylinder heim joint is attached and secured by an "L" bracket attached to the frame. I think I'll try to adjust it before an entire tear down.

Can the problem really be a contaminated disc? I would think the clutch would slip before any chatter would occur. Also, wouldn't chatter occur in every gear if the disc was contaminated or the flywheel was warped?

If I feather the engine and clutch just right, I can virtually eliminate any chatter (except on an incline).

The driveline appears to be fine and I am not having any rear main leaks. I think I can rule out anything from the drive shaft back.

The fact of the matter is that something is seriously wrong and baring a simple slave adjustment, a complete breakdown is iminent. Unfortunately, I lack the free time needed to drop the transmission and make any repairs. I will try to find a knolwedgable and honest mechanic here in Northern CA.

I think the easiest way to simplify what is happening is to say that the problem occurs when the clutch disc is releasing from contact with the flywheel. I believe it it one of three things would cause this:

1. Slave cylinder
2. Clutch disc or flywheel
3. Missing or out of round Pilot Bushing

Thanks everyone,

Mike

Mike,
I can recommend Gary Cook at GT Auto in Rancho Cordova, excellent/honest mechanic with lots of experience on Cobras etc. Please keep us informed/updated of the repairs. Good luck.

I'd bet that this is it. That would be the first thing I did before tear-down.
