Dear Hickling, Our production people sent you the other day a pinion bearing in which there had been a failure of the steel cage. This is now not the only one, as another has come to hand from a customer in France. I do not know what you suggest is the cause of the trouble, but this latter bearing looks as if it had had insufficient lubrication. We think it would be a good idea to revert to the oil grooves which were in the original Hoffmann bearing. As we have another Bentley going to France shortly, could you let us have two such bearings to try, and also let us have your views on any other means of overcoming the trouble. Yours sincerely, FOR ROLLS-ROYCE LIMITED. | ||
