Coverley - Production Engineer} from Hs{Lord Ernest Hives - Chair}/Rm.{William Robotham - Chief Engineer} Hs{Lord Ernest Hives - Chair}/Rm{William Robotham - Chief Engineer}3/LG9.6.27 X7430 FRONT AXLE. X7420 We are very interested in the considerable difference which we find in various axles and their effect on steering. So far, the only marked discrepancy which we have observed between two axles is in the bedding of the pivot pin bearing. If these are not very evenly bedded, the steering is heavy. Will you please examine the bumper axle which was recently fitted to 12-EX as regards vertical king pin clearance, true running of the hubs and thrust bearing bedding. We wish to compare it with the axle now fitted to 12-EX car. Hs{Lord Ernest Hives - Chair}/Rm.{William Robotham - Chief Engineer} | ||
