| 4995 S/W....Hs{Lord Ernest Hives - Chair} c. to Wor.{Arthur Wormald - General Works Manager} E.{Mr Elliott - Chief Engineer} BY.{R.W. Bailey - Chief Engineer} C4/07.3.35 RE USE OF THIN OIL. Hs{Lord Ernest Hives - Chair}2/MJ6.3.35 We are naturally relieved to know that you do not consider the failure of the bearings on 21-G-4 was due to the use of thin oil. As a matter of interest we should like to know what you consider the cause of the failure, because, of course, the bearings of Rolls-Royce cars, even when made of the white metal as at present, are not expected to require renewal under, say 60,000 - 80,000 miles - and even allowing for the strenuous tests you put the car to, this should still be very considerably in excess of 15,000. Vacuum "Clearosol" You will no doubt have noticed Wakefield's announcement of a new oil, and the many claims they make for it, amongst others its more or less permanent viscosity. Will you be trying this out? C. | ||
