GREASING WHEEL BEARINGS
346-347 wheel hub and brake drum bearings which are not provided with grease fittings should be cleaned and
repacked with high melting point grease (Valvoline No. 2 1/2 or its equivalent) whenever the wheels are removed.
When steam, air or water pressure are used for cleaning the motorcycle, the wheel bearings must be lubricated at 2000-mile intervals to prevent damage to the bearings, due to washing out of the lubricant and to remove any foreign matter which may have been forced in by the pressure cleaning.
All wheel bearings of this type must be lubricated at intervals of 2000 to 6000 miles, depending on the type of service, road and weather conditions under which the particular motorcycle is operated.
