BENTLEY 11.A. REAR AXLE. GB.2788./DIFF. BOX. Referring to HPS.{Horace Percy Smith - Experimental Factory Mgr}/RH.{R. Hollingworth}1/VS.{J. Vickers}18.11.37. we note the shoulder which has been produced on the differential casing 5.B.lV and 6.B.lV. We have, however, appreciated that there was a fault here and increased the length of the loose collar to keep the ball bearing from working on the end of the radius. This matter can now be considered to be completely cleared up. BY.{R.W. Bailey - Chief Engineer} | ||
