Hancock - Head Chateauroux} from Rm{William Robotham - Chief Engineer}/Gry.{Shadwell Grylls} Rm{William Robotham - Chief Engineer}/Gry{Shadwell Grylls}6/R.11.9.37. [STAMPED: SEP 13] You have recently sent us a pinion bearing with a broken cage. Sometime ago we wrote to KC. asking him to take special note in cases of cage failure as to whether the nip on the pinion bearing was correct. We have reason to believe that cage failures are due entirely to the bearing running slack, but want to get confirmation of this. Could you let us know any more about this particular bearing ? Rm{William Robotham - Chief Engineer}/Gry.{Shadwell Grylls} [Handwritten:] Gry{Shadwell Grylls} for Rm{William Robotham - Chief Engineer} [Handwritten Note:] PM/GWH{George W. Hancock - Head Chateauroux} The nip on this bearing was correct we check all of them as a standard routine WH | ||
