Hs{Lord Ernest Hives - Chair}/Rm.{William Robotham - Chief Engineer}1/AD23.11.31. 18-8-94 CROSS STEERING TUBE LOAD Recently in the Test Dept. we have come up against the fact that when you tighten the bolts on the cross steering tube it is possible to trap the brass pad in front of the spring and prevent it following up anywhere with spring pressure. With quite normal tightening of these bolts the spring in the cross steering tube can, to all intents and purposes, be rendered inoperative. We believe that you have been aware of this trouble before but are not sure whether you appreciate how easily it can produce the effect of which you have so frequently complained i.e. the loss of cross steering tube load after a short mileage. We are at once taking steps to overcome this trouble but shall be interested to know whether you can reproduce it on 18-GIV and furthermore if, when you take care that trouble does not occur, you find that your cross steering tube load remains consistent. Actually, the clearance given to the brass pad is only .001 and it is probable that with .003 to .005 clearance the trouble would be completely overcome.
