Coverley - Production Engineer} E.2/HP.18.1.37. re 3/4 Floating Axle. With reference to the discussion which took place on the 3/4 floating type of axle, it is interesting to note that in the instruction book of the 22 HP. Ford considerable emphasis is laid upon the importance of keeping the axle shaft nuts tight. Under group (1) lubrication and maintenance is a special heading in heavy type "AXLE SHAFT NUTS", with the following note:- "These should be tightened after the first 300 miles of operation, and not allowed to become slack subsequently". Again under the heading "THE REAR AXLE" later in the book, the following sentence appears:- "The axle shaft nuts which hold the hubs in place should be kept tight at all times to prevent damage to the taper on either the axle shaft or hub". In connection with this same design of axle, it is also noted that in the event of a failure of the axle shaft there is no provision for retaining the rear wheel on its bearing on the axle tube.
