Coverley - Production Engineer} Ws/Rm.{William Robotham - Chief Engineer} E/HDY.{William Hardy}1/HP.15.1.36. Clutch - 25-30. We send herewith N.Sch.4732 which shows the pressure plate springs we propose for this car with the R.R. clutch already referred to in our E/HDY.{William Hardy}2/HP.13.1.36. To get the lowest possible rating we have lengthened the spring caps as much as the operating shaft boss permits, and we ask for the boss to be machined to reduce the clearance variation. N.Sch.4732 herewith. E/HDY.{William Hardy} | ||
