| Rm{William Robotham - Chief Engineer} x7961 NO. c. Hs.{Lord Ernest Hives - Chair} BY.5/G.4.2.35. CHASSIS NO. B.31.CW. T.F. BLACKWELL, ESQ., MILEAGE 422. RE: REAR AXLE PINION PICKING UP. With reference to K/KC/DPB/30.1.35. which we return herewith, whilst we consider the views put forward by Kingsbury are quite sound as a generalisation, we have not so far encountered trouble owing to Whitmore's Compound becoming too thick to flow reasonably, and of course temperatures in America, where Whitmore's Compound is freely used, are considerably lower than in this country. I am inclined to think that the pinion was bearing too much on the inner end of the tooth, but so far I have not had an opportunity of examining the actual gears. The evidence given in the memo quoted above appears to indicate that low temperature may have some bearing upon the matter, although as pointed out above we have not so far any evidence apart from this particular case which would force us to this conclusion.
