| To E.{Mr Elliott - Chief Engineer} from Hs{Lord Ernest Hives - Chair}/GWH.{George W. Hancock - Head Chateauroux} c.c. to Hs{Lord Ernest Hives - Chair}/Rm.{William Robotham - Chief Engineer} X300R (2) Hs{Lord Ernest Hives - Chair}/GWH.{George W. Hancock - Head Chateauroux}29/KW.7.10.35. Phantom III. 31-EX. Distributors. At your request not to accept the excessive lift of the head of the distributors, we have had the clearance cut down from .010 to .002". This has reduced the shake of the distributor head to a minimum with no appreciable stiffness in the hand control. There is still quite an amount of backlash in the drive. This is attributed to the necessary clearance required in the centrifugal mechanism. Hs{Lord Ernest Hives - Chair}/G.W.Hancock. | ||
