I just completed swapping a Muncie m21 into my 72 skylark (350, formerly had a th350 trans). I am very happy with the swap so far except there are a few small problems. I went with a hydraulic clutch using a Howe bearing and a Wilwood master cylinder, it feels great but the clutch grabs kinda high for my taste, any way I can change this without altering the pedal height? Also I notice the clutch makes a whining sound similar to that of a bad power steering pump when the clutch is not depressed, if I put even a little tension on the clutch pedal it goes away. I was very careful when installing the throw out bearing to make sure the clearance between it and the pressure plate were correct so I do not believe that's the issue but hey I've been wrong before. Maybe someone can help me out on this, any advice would be greatly appreciated!
More than likely the throw-out bearing is the culprit in that type of noise. What did you set the clearance at from the fingers of the fork when the hydraulic throw-out bearing was installed??? If I remember correctly it's supposed to be set at .300". This number takes into account how far the fingers will come out during normal wear of the disc. Tom T.
If I remember correctly I did set it to .300", which with my set up did not require any spacers. It was not making the noise when I first installed it, is it possible that the clutch has worn and this causes the noise? Other than the noise I havent noticed it driving any differently.
In my opinion not likely. I still stand behind the throw-out bearing being the culprit. Before ripping & tearing do some diagnostics before hand.
