| To DA.{Bernard Day - Chassis Design} from Hs{Lord Ernest Hives - Chair}/Rm.{William Robotham - Chief Engineer} Hs{Lord Ernest Hives - Chair}/Rm{William Robotham - Chief Engineer}1/LG31.5.27. AXLE CONTROL. X8420 With reference to DA{Bernard Day - Chassis Design}4/M27.5.27. We have carried out a test in which we have removed the shock damper from the frame with the engine in position without excessive difficulty. With reference to the 12" lever. We certainly cannot detect the effect of quarreling with this lever on the road but we feel it may produce excessive wear on ball ends and bearings. We have used flexibility in the ends of the torque arm allowing 2° axle movement either way which would appear to make the use of a lever any convenient length possible. We are anxious to standardised the torque control at the earliest possible moment so should be glad to hear from you whether R.{Sir Henry Royce} is likely to agree to it going through in its present form, or whether alterations will be made in which case it is no use our rushing tests on the present design.
