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

[NorCal Cobra]

I guess I should have mentioned that I completely changed my slave cylinder configuration two weeks ago.

That last slave cylinder (non -Willwood type) blew out was not secured to the frame. It was just butted up against a hole in the bellhousing with the clutchfork tension acting as the securing device. No wonder why it blew out!!

It was a very poor setup and the new Wilwood cylinder I received required modification to keep it secure and free from excessive play.

I have had clutch chatter before and after changing to the Wilwood, but now the chatter is much worse.

It could be a combination of slave setiup and disc contamination. Who knows????????

Al,

My first wilwood was mounted as yours was, it failed. The second came with instructions to mount it on the frame. It chattered & failed. I made my own mount for the third one. It is holding up fine. Another issue with some Wilwoods is that the piston unscrews from the rod. This was a part of my problem with the second one. I really believe the vibration from the two mountings you have tried could be the cause or a part of the cause of the failure and the chattering. It won't cost much to try a solid mont to the engine before embarking on a transmission & clutch removal.

Good luck, Paul
