I have gone thoroughly over the above question again and the O.O. definitely confirm from their records that, until now, no attempt has been made to use the above type of ball bearing for side location purposes. Wd{Mr Wood/Mr Whitehead}, also informed me that Messrs. Hoffmann when approached by him, to change the bearings delivered to above type, at once stated that we were now asking for something we had never called for before. In view of the above, which leaves no doubt in my mind as to our prewar practice, I certainly do not consider that the fitting of the locating bearing which includes an entering slot for the balls, is a feature which can be considered dangerous and which would therefore demand the sending out of a fitter to replace the bearings in question on chassis delivered. My attitude in regard to this question is strengthened by the consideration that if we start out on such a procedure without definite evidence that the supposed faulty bearing is a danger then we must face the fact that there will be a large percentage of our prewar cars which will have to be dealt with similarly. I therefore contend that unless we have direct evidence showing that the ball bearing with an entering slot contd. | ||
