Information:
1. Exploded viewsIn the exploded views, the component parts are separated but so arranged to show their relationship to the whole. Index numbering is used to identify the parts and to indicate a sequence in which the parts are to be removed for disassembly, or they are to be installed for assembly. 2. SymbolsThe following symbols are used in this manual to emphasize important and critical instructions:
Indicates a condition that is essential to highlight.
Indicates a condition that can cause engine damage.
Indicates a condition that can cause personal injury or death.3. Definition of locational termsThe fan end is "front" and the flywheel end is "rear". The words "left" and "right" are as these directions would appear from the flywheel end.4. Dimensional or specification termsNominal size...Is the named size which has no specified limits of accuracy.Standard...Is the dimension of a part to be attained at the time of assembly, or the standard performance.Limit...Is the maximum or minimum permissible limit beyond which a part must be repaired or replaced.5. Tightening torquesTighten bolts, nuts, etc. in a wet condition (apply oil to threads) when specified as [WET]. Tighten them in a dry condition unless so specified. Use the general torques unless otherwise specified.MODEL IDENTIFICATION AND SERIAL NUMBER LOCATION
1. Model identification location(a) The model identification is embossed on the right side of the cylinder block, near the fuel injection pump mount.(b) The model identifications and displacements of the engines in current production are as listed below:
Model identification location(c) A scheme of coding used for identifying the engines in current production is as follows:
Example: Coded designation2. Serial Number LocationThe serial number is punched on the cylinder block, near the fuel injection pump mount.
