| 1153 To LA.{L. A. Archer} from Rm{William Robotham - Chief Engineer}/Gry.{Shadwell Grylls} Rm{William Robotham - Chief Engineer}/Gry.{Shadwell Grylls}7/AP.4.1.38 We have sent over to you Over-Drive Gearbox No.15.HS.{Lord Ernest Hives - Chair}, As this has been sitting on the floor for several months since it was last assembled, we think it would be advisable to do some initial running on Hi-press oil so as to avoid seizure of the steel bushes. There is no reason why this oil should not stay in during the whole of your test. Rm{William Robotham - Chief Engineer}/Gry.{Shadwell Grylls} | ||
