K, update----Well, Well, Well, Sprinters what a pile of poo! It appears I have found my first SAC (self adjusting clutch) There is a special tool that needs to be fitted to the pressure plate before assembly, this tool holds down the spring fingers all the way in, then when the complete clutch if fitted the springs release to the correct position!!! Failure to fit the clutch correctly results in NO clutch!!! (Ask me how I know)
