Coverley - Production Engineer} Bentley Rear Axle. Herewith is N.Sch.4610 which shews an extension of the hypoid pinion shaft, the object of which is to raise the critical speed of the propeller shaft. The arrangement goes on to the existing centre casing, and most of the pieces are as now. The pinion is intended to be the 10/43 combination as it is the increased speed of the engine with this combination that causes anxiety. It is also desired, during the course of the tests, to remove experimentally the tail roller bearing of the pinion, with a view to trying it as an overhung pinion, so as to gain information. An improvement in the spacing of the bearings with the overhung pinion can be obtained by using two "Radax" type single row bearings instead of the standard double row type, but this will be dealt with later if thought desirable.
