Old Britts – Norton Commando Torque Settings
Download the complete PDF version using the green download button at the top right of this page for a detailed Norton Commando torque settings reference covering the gearbox, engine, timing case, primary drive, front forks, wheels, Isolastics, brake caliper, oil tank fittings, footrests and many other commonly serviced assemblies. This Old Britts workshop chart is a valuable reference when rebuilding, maintaining or checking fasteners on a Commando.
This comprehensive torque guide lists the recommended tightening figures for a wide range of Norton Commando nuts, bolts, studs and screws, with values provided in ft lb or in lb as appropriate. It also includes important notes where special care is needed, such as the clutch-to-mainshaft nut torque recommendation, stainless fastener anti-seize guidance and the effect lubrication can have on torque readings.
In addition to the torque tables, the document provides tightening orders for the gearbox inner cover, cylinder head, 750 and 850 cylinder bases and timing cover. A separate section explains the correct assembly and torque procedure for the Norvil front disc arrangement, making this a practical workshop companion for both routine maintenance and more involved Commando restoration work.
