Our recommendations for the above are that the flywheel should be to Ex.20150 and the 1st motion shaft to Ex.20185. Crankshaft rear end, trunnion assembly, lubrication and gearbox front cover to be as on the Bentley scheme. We require the 3.000" operating lever Hs.{Lord Ernest Hives - Chair}2159. The short lever on the other end of the adjusting link will have to be modified to avoid a foul with the lock nut. We are obtaining from Borg & Beck a final layout of the clutch, showing dimensions and limits. Hs{Lord Ernest Hives - Chair}/Smth. Att : Ex.20150, Ex.20185, Hs.{Lord Ernest Hives - Chair}2159.
