SERVICE RELEASE N31

NATURE OF RELEASE: Breaking-- in oil end oil changing MODELS AFFECTED: All Commando DISTRIBUTION: Worldwide (General Distribution) EXPLANATION: As a result of development experience it has been found beneficial to speed up the initial breaking - in process for the engine unit. The recommended oils provide such o. degree of'protection that the rubbing surfaces require an extended period to. bed satisfactorily. A different grade of oil willin future be used for initial bench teeting of new engines and the nearest grade commercislly available should be used for the first 500 miles. At the 500 mile service it is most essential for the oil tank end crankcase filters to be cleaned out thoroughly during oil changing. Use Castrolitc for the initial fill of the oil tank. At the 500 mile service revert to the handbook recommendation.   January 1971 Norton Villiers Canada Limited
