Eric Platford - Chief Quality Engineer} R5/M26.4.23. GOSHAWK CRANKSHAFT. X4221 I suggest that we go ahead to prove that the larger shaft with same size crankpin is the best scheme which it is easy and practical to apply. This should be standardized as early as possible pending the 10000 mile trial which can be done during production, but before delivery. It should be realised that this should have no effect on the torque re-action vibrations, unless we do not know what they are. R.{Sir Henry Royce} | ||
