1 Introduction This parts manual applies to the Performer engine as listed in the Engine Data T able. Parts are arranged in groups of related items and each illustrated part is identified by a reference number corresponding to the same reference number in the parts list. Parts illustrations are typical. Throughout this manual, right and left sides are determined by facing the flywheel end (FRONT) of the Engine. Using the MODEL and SPECIFICA TION NUMBER from the nameplate, consult the SALES OPTION CODE T ABLE in the back of the book to identify factory installed parts that are unique to your engine. (Note: The diagonal line (/) in the model and specification number separates engine characteristics from the specification number and letter . The specification number denotes customer requested features. The specification letter advances (A to B, B to C, etc.) with major manufacturing changes.)
