Hi All
I have a question on the 1928 clutch set up. When the flywheel is correctly refaced, the pressure plate correctly refaced and assembled with a new clutch disc of the correct thickness, what is the approximate distance from the front of the throw out bearing sleeve flange to the back side of the pressure plate housing when the sleeve is installed and the clutch engaged??

I have a customer that I sold the flywheel, pressure plate assembly and new Billy Possum clutch disc to and he had the pressure plate and flywheel refaced himself. He said he has 1/4 inch clearance between the front face of the flange of the throw bearing sleeve and the back of the pressure plate housing where the sleeve goes in. Is this enough? Any thoughts or replies would be appreciated. As far as he can tell, everything is installed correctly.

sounds about right, the clearance will increase as the clutch wears. you can get an idea of how far the sleeve moves by measuring the linkage, and doing some math. Another thing you can do, is assemble the clutch in the flywheel, put the sleeve in, put it on a press, and press the sleeve down until the clutch releases (or almost hits the pressure plate). Put a clutch alignment tool (transmission input shaft) into the clutch from the bottom, you can turn it when the clutch releases. I did this to test my clutch, which I "rebuilt" myself.
