VARIATION IN CROSS STEERING TUBE LOAD X.7425. X.5425. From time to time complaints have been made that the qualities of Phantom II steerings have deteriorated owing to the cross steering load varying. It has now been discovered that it is possible to nip the inner bronze contact piece of the cross steering tube by tightening up the biting in bolts. If these bolts are tightened up normally a certain amount of restraint may be imposed upon this piece, while if the nuts are tightened up with excessive energy a point can be reached where the brass pad will not move at all under spring pressure. To cure this state of affairs on existing cars it is only necessary to increase the clearance between the brass pad and the tube to .005. The position on the 25 HP. is not so serious and satisfactory results can be obtained by ensuring that there is .003 clearance between the brass pad and the tube. In each case material is removed from the brass pad and not the tube. Hs{Lord Ernest Hives - Chair}/Rm.{William Robotham - Chief Engineer} | ||
