Recent and all future B. & B. clutches will be found to have castellations on the eyebolt adjusting nuts. This feature has been introduced to facilitate the initial setting of the operating fingers, but must not be regarded as a means of adjustment in service stations. We have found the adjustment to be a very tricky process if it is to be done satisfactorily, and faulty clutches should be returned to the Works for correction on a special rig. Will you please advise service stations accordingly. Rm{William Robotham - Chief Engineer}/Smth. | ||
