Bailey - Chief Engineer} RHC.{R. H. Coverley - Production Engineer}5/MJ.9.6.37. Re. Chassis No. 3-AX-185. We have looked into the complaint in your memo. Sr.5/E.3.6.37 and cannot give any explanation for an axle being fitted up in this manner. The Test Dept. always seal the rear drivers and do not necessarily remove the drums except in the case of any brake complaint. Their records do not shew any brake query, therefore they have not removed the drums and drivers. It is possible for the studs to be missing, and be sealed by the Test then passed off as O.K. We must ask whether or not the seal was intact when it was found necessary to dismantle the hubs. We would also like to know the reason for dismantling. We cannot deny the possibility of fitting up a job in this very careless manner, although it is remote. We would appreciate the fullest circumstances being given before we instruct the Test Department to strip down every hub before sealing. On the question of noisy ball bearings we do not examine bearings to ensure that the balls are of equal size, neither do we consider this checking necessary. We will, however, take this point up strongly with Hoffmanns. We have never encountered a ball bearing having this defect, and are thus very anxious to see it. The question of nut sizes is being investigated, and our recommendations will be made on this point. RHC.{R. H. Coverley - Production Engineer} | ||
