| Hs. {Lord Ernest Hives - Chair} Mr. [crossed out] X5010. BY19/G.26.5.30. 20 HP. CHASSIS - CRANKSHAFT. -------------------------------- Mx. {John H Maddocks - Chief Proving Officer} has reminded me of a point that slipped my memory previously viz. that when we step up on the strength of the 20 HP. crankshaft we completely eliminate the "bus" knock. It is, however, conceivable that the stronger shaft might bring it back, and it is a matter of trying it out whilst the issue is still an experimental one. BY. {R.W. Bailey - Chief Engineer} By | ||
