| X 2066 c. Dft. c. Hs.{Lord Ernest Hives - Chair} BY5/G.5.7.29. 40/50 HP. CHASSIS - HYPOID AXLES. The Experimental Department would like us to test out a number of the above axles with Castrol 'R' oil instead of Whitmore's compound. We would suggest that we might run one third of the axles on Castrol "R" and if at the end of a month all is going well we might increase to 50%. Axles must be despatched with the type of oil they have been tested with. BY.{R.W. Bailey - Chief Engineer} Br | ||
