| X212 To EY. from HDY{William Hardy} HDY.{William Hardy}1/HP.23.5.35. c. Wer. Ey. Hs.{Lord Ernest Hives - Chair} Da.{Bernard Day - Chassis Design} REG. Bentley Clutch. N. Sch.4502 herewith shows a stiffened flywheel cover for this clutch. We show dotted the forging for the existing cover C.56927 which it appears to us has a sufficient margin to clean up for the new cover. We have not reduced any important clearances. Flats must be provided on the flanges of the needle bearing races and slight shortening of the aluminium distance pieces to the springs is necessary. We ask for double the number of bolts between the cover and the flywheel. The cover should be tried both with and without the increased number, to determine whether there is any noticeable difference. HDY.{William Hardy} N.Sch.4502 herewith. | ||
