| 200a. Rm{William Robotham - Chief Engineer}/GWH{George W. Hancock - Head Chateauroux}/IMW.{Ivan M. Waller - Head of Chateauroux} from Rm{William Robotham - Chief Engineer}/Gry.{Shadwell Grylls} c. Rm{William Robotham - Chief Engineer}/GWH.{George W. Hancock - Head Chateauroux} Rm{William Robotham - Chief Engineer}/GryS/R.17.3.37. 3.B.IV. Your Daily Reports have already answered part of our questions about oil leaks on the rear axle. We presume that the oil leak of the pinion housing to which you refer is at the point marked with an arrow on the attached N.Sch. 4985. If you will confirm this, we will send you out an oil seal housing stiffened up as shown by pencil. If, on the other hand, the leak is passed the oil seal, the seal may be fitted the wrong way, or may have been damaged in assembly, in which case we could send you another. On the N. Scheme you will see that the idea is to have an increased oil level, but we are not running this on 3.B.IV, the oil level being standard. Also on this car you have a propeller shaft sliding joint lubricated by oil with a new arrangement of baffles to prevent the oil escaping; possibly this is not working freely. If you take it apart, please note that the two halves of the brass retaining ring are heldited together to prevent leaks at the joint. 35-EX. Two features we want standardised on this car are - the new radiator stays and the 5" rim wheels. Will you have a look at these and see whether they are still all right. On a memo sometime ago you said one of the rear jacks was leaking. Will you send us a sketch of where the leak is taking place. Rm{William Robotham - Chief Engineer}/Gry.{Shadwell Grylls} | ||
