SERVICE RELEASE N25

NATURE OF RELEASE: Identifying marks on assemblies MODELS AFFECTED: DISTRIBUTION: Worldwide (Trade Only) EXPLANATION: From queries received we gather that our system of stamping a Factory identification symbol on certain assemblies (for example: the marking "X" on the top of the rear engine mounting boss) is causing some confusion. We respectfully point out that such markings are purely a Factory Facility to enable us to keep traok of any production changes without the need for stripping. Such markings will appear only for a limited time and then disappear whereas the feature may well continue. As such, we shall . only make known the purpose of markings where we feel common knowledge is mutually advantageous, One such example is given below:- MARKING: "X" stamped on top of rear engine mounting boss. PURPOSE : To identify for fitting on assembly, engines with the modified middle piston ring (Service Release No: N. 13 refers). In view of the temporary nature of this marking, all that can be inferred that any engine with the aXn has the modified middle rings and in the unlikely case of overcoiling, the cause lies elsewhere.   November 1970 Norton Villier Canada Limited
