| X.3806. To Oy. from Hs{Lord Ernest Hives - Chair}/Tsn. Hs{Lord Ernest Hives - Chair}/Tsn2/ADL9.10.29. CENTRAL LUBRICATION We should be glad if you would send us information on the following points :- (1) Have you succeeded in eliminating the soldered joint from the system entirely by using Bijur's new duralumin drip plugs? (2) What is the reliability of the olive joints, as regards freedom from leakage, compared with soldered joints? (3) We should like a layout of your present system using the latest type drip plugs, and including lubrication to the axles. (4) To what limits of accuracy do you hold Bijurs for metering of drip plugs? We call for 10%, and they complain rather. (5) Do you test a certain percentage of them yourselves on receipt? (6) How much do you pay for each plug? Hs{Lord Ernest Hives - Chair}/Tsn. | ||
