Norton Commando Workshop Manual – Circa 1969
Download the complete PDF version using the green download button at the top right of this page for the original Norton Villiers Commando Workshop Manual, covering the early twin-cylinder Commando in substantial mechanical detail. This factory service reference was prepared for owners carrying out their own maintenance, as well as dealers and repair workshops responsible for complete engine, gearbox, chassis and electrical work. It includes specifications, service procedures, exploded diagrams, workshop illustrations and technical guidance for maintaining and overhauling the early Norton Commando.
The manual begins with recommended lubricants and a detailed explanation of the lubrication system, including the oil pump, pressure relief valve, crankcase release valve and oil pressure checking. It then moves into engine service and overhaul, covering decarbonising, cylinder head removal, valve guides, pistons, rocker assemblies, camshaft work, crankshaft removal, bearing replacement, timing gear setup and engine refitting. Several pages include factory drawings, dimensional diagrams and photographs of workshop operations.
Further sections cover the Commando gearbox, clutch, primary chain adjustment, rear chain adjustment, front forks, frame assemblies, Isolastic engine mountings, swinging arm, wheels, hubs and brakes. The electrical chapter includes carburetter notes, alternator testing, Zener diode charge control, contact breaker service, rectifier information, battery guidance and wiring diagrams. The final pages also provide additional notes for models after engine number 131257.
