| Rm{William Robotham - Chief Engineer}/Gryll/R.{Sir Henry Royce} 22nd Sept. 1937. F.O. Hickling, Esq., Messrs. Ransome & Marles Bearing Co.,Ltd., NEWARK-on-TRENT. Dear Hickling, I am sending off to you a double row bearing M.D.J.T.1¼" which has run actually about 150 miles in one of our gearboxes. It has been turned down because of noise. If you turn the bearing round by hand, you will notice that it has a very lumpy feel. In sending this bearing back we are now short for our next gearbox, and hope that you will be able to re-condition it; it will probably be quicker than supplying a new bearing. The surface of the races looks as if a lot of dirt had become included, and I do not know where this has come from. Yours sincerely, | ||
