| from E.{Mr Elliott - Chief Engineer} Copy to Exp. EPC. X4254 E C FEB 9 1932 ORIGINAL. RECEIVED INTER-DEPTAL INTERVERBAL - "GOSHAWK II" D 3 H1/G/12/1931. 21/DEC/31. RECEIVED With reference to N. scheme 738, the possibility of the oil oozing out via the thread of the bearing retaining nut has been brought about by the adoption of fig. 7 N.Scheme 698. To do away with this trouble Mr. Royce would prefer to go back to the use of a nut on the inner end of the housing. This will mean, of course, increasing the size of the flange on the axle casing and bevel pinion housing. To this latter point Mr. Royce has no objection, as he thinks the present attachment is, if anything, on the weak side. The interior arrangement of ball bearings, thrust washer, and distance pieces should not be altered, but the outer end of the casing will now be blind, and to save a feature in the machining, and also to provide an undercut for grinding the bore, etc., the end should be extended a little, and made square to include the oil retaining compartment, as in sketch - Referring now to the means of holding on the nose bearing race, Mr. Royce wishes to use a long cheese headed screw put in from the outer end, and securing the bearing washer by means of a castellated nut, for which latter piece there appears to be enough room in the axle box.
