Dear Sirs, We do not appear to have anywhere in our records a figure for the finger ratio of the clutches you have supplied us with; i.e., the ratio of the movement of the trunnion to that of the pressure plate. We should be glad of this figure, both for the 10" and the 11" clutches. Yours faithfully, FOR ROLLS-ROYCE LIMITED. | ||
