SERVICE RELEASE N64

NATURE OF RELEASE: Heat damage to rear wheel cush drive MODELS AFFECTED: 1971 and later Commando PARTS AFFECTED: 062074/062075 Cush drive buffers DISTRIBUTION: Worldwide (for General Distribution) EXPLANATION: If the rear brake is adjusted incorrectly so that it binds, considerable heat will be generated. It is important to note that the polyurethane tush drive buffers will suffer permanent damage if subjected to excessive heat. A secondary cautae of exess heat in this area is a lack of lubrication at the brake drum bearing.   ACTION: Take particular care in brake adjustment and bearing lubrication. Whenever the rear wheel is removed, check the condition of the tush drive buffers and renew if necessary. September 1971 Norton Villier Canada Limited
