I'm not sure what you are refering to? The throwout bearing is on the input shaft of the transmission, it has nothing to do with the camshaft. First of all who installled the cam bearings? Thake the block back to them or make them give you some input on this problem. You will need some specialized measuring and installation tools for this problem to be corrected, which a shop would only have. Visualy check the journals on the cam for any irregulaities. Will the shaft go in far enough so the front journal is below the shoulder at the front of the block? Is the installation of the thrust plate causing the binding?
