LUBRICATION OF AXLE CONTROL BALL END. Replying to BY4/G19530., the question of whether the oil would reach the ball or not had occurred to us, and we agree that there is some doubt about the matter. We thought however that if we could get oil into the cylindrical cavity so that it would touch the ball it would gradually work its way round. We agree that it would be desirable to do something to make sure, for instance, as suggested in your sketch, by making the bronze ball pad with a slot at one side only, and drilling into the centre. We suggest that this might be done by drilling to one side as indicated on N. scheme 3108. nerwith. The oil even then is not permanently retained, but probably it is better than the original proposal. DA.{Bernard Day - Chassis Design} | ||
