| BY.{R.W. Bailey - Chief Engineer} from DA.{Bernard Day - Chassis Design} C. to BJ. Hs.{Lord Ernest Hives - Chair} X7340 DAL/M17.5.28. CENTRALISED CHASSIS LUBRICATION. X.7340 X.3806 X.8340 Herewith we send N.Sch.2603 - modification to the lubrication of the universal joint and torque sphere in order to dispense with the working coil etc. The modification calls for a slight alteration in the machining of the sphere, namely, an increase in the external radius between the sphere and the stem. As far as we can see there is still plenty of clearance for the movement of the sphere. If there is any difficulty, for instance already machined parts being in existance, perhaps you will let us know. DA.{Bernard Day - Chassis Design} | ||
