SERVICE RELEASE N62

NATURE OF RELEASE: Damage to oil pipe by chafing MODELS AFFECTED: Commando 1971 (all models) PARTS AFFECTED: Oil pipes, 062201 (Feed) 062200 (Return) DISTRIBUTION: Worldwide (Trade only) EXPLANATION: If contact should occur between the oil feed and return pipes and various cycle parts, there is a possibility of oil loss if the pipes should be rubbed through. To counter this, we are repositioning the pipes and also introducing re-inforced pipes which have a much greater resistence to damage. The same oil pipe numbers continue and future spares supplies will be of the later type.   ACTION: Examine the oil pipes carefully for evidence of fouling and reposition as required. The points of foul which should be checked are: a) Between the rear fender and the point where the metal oil return pipe enters the flexible pipe behind the oil tank. b) At the sharp edge of the machined face where the oil tank strainer union abuts to the rear of the tank. c) At the horn. (On later models the oil pipe clip is re-formed to hold the pipes clear of the horn). Should the horn slacken on its mountings, this can result in further fouling . To re-secure the horn, remove the rear fender to gain access. Check that the centre bolt does not bottom in the casting and shorten if necessary before retightening. d) At the front of the right frame gusset plate adjacent to the rear engine mounting. e) At the front of the battery tray. If the pipes show signs of wear as a result fouling, replace with the later re-inforced oil pipe. September 1971 Norton Villier Canada Limited
