SERVICE RELEASE N32

NATURE OF RELEASE: Lubrication of rear brake drum bearing MODELS AFFECTED: 1971 Commando (all models) DISTRIBUTION: Worldwide (for general distribution) EXPLANATION: 1971 models use an additional bearing in the rear wheel assembly, located in the rear brake drum. It is recommended in the Handbook that the wheel bearings be repacked with grease at 10, 000 mile intervals. This figure is correct for all wheel bearings excepting that in the sprocket. The bearing in the sprocket requires more frequent attention due to the heat generated by the rear brake   ACTION: Whilst examining the shock absorbing pads at 5, 000 mile intervals examine also the sprocket bearing and if necessary repack with the ecommended grade of grease. After, the rear wheel has been removed, leaving the sprocket in situ, it is only necessary to lift out the bearing spacer from the sprocket, followed by the dished washer and seal. The dished washer will be removed most easily with a small screwdriver blade. On eassembly, secure the dished washer by centre punching at each side. March 1971 Norton Villiers Canada Limited
