| 87425. To BY.{R.W. Bailey - Chief Engineer} From Hs{Lord Ernest Hives - Chair}/Les.{Ivan A. Leslie} Hs{Lord Ernest Hives - Chair}/Les.2/MJ.26.11.31. X.7425. X.5425. CROSS STEERING TUBE POUNDAGE. Complaints have been made from time to time with regard to the cross-steering tube poundage diminishing. This is due to the end piece brazed into the tube collapsing and gripping the inner ball end pad. Although this can be avoided by refraining from tightening the biting in bolts too much, it can be eliminated by an extra clearance between the pad and the end piece brazed in the tube. On Phantom 11 the clearance between the end piece G.77466 and ball and pad G.77462 is at minimum .001". This should be increased to .005 as a minimum clearance. Will you therefore alter the drawing G.77462 making the present dia. 1.074-1" into 1.070-1". On 25 HP. we find the fault less pronounced due to the thicker end piece G.53597 although a similar action does take place. We find an additional .002" to be sufficient. This makes the inner ball end pad G.53599 .653-1" dia. instead of the present dia. .655-1". Will you please modify this drawing. Hs{Lord Ernest Hives - Chair}/I.A.Leslie. | ||
