Answering your BY/RD4/W28.3.33. we are anxious that there should be no delay in bringing on production the Phantom II self lubricated bearings for the starter motor. The scheme as tried out on the bench and on 10,000 miles test gave every satisfaction, and is obviously superior to the Peregrine in that with the larger motor a much larger reservoir of lubricant is possible without increasing the general bulk of the motor. In fact on the Phantom II it is imperative that we get the scheme going as soon as possible on production due to the fact that in frosty weather the motor generally refuses to move into gear due to the excess of oil in the large plain bearings freezing up. This was proved in the Expl. Dept. by GWH.{George W. Hancock - Head Chateauroux} The pad scheme only allows the minimum of oil in the bearings and providing the reservoir is ample, as in the case of the P.II., no trouble should be experienced.
