Section XVII. ENGINE SPECIFICATIONS
OVERVIEW
This section provides quick location of specifications and wear limits needed to maintain, repair, or
overhaul the diesel engine and its components. Wear limits indicate that a part may be reused at the
worn limit but must be discarded if worn limit is exceeded. Specifications are given in US standard and
metric measurements.
This section is numerically structured in repair section number order to aid in locating pertinent infor-
mation for a specific system. Example: SECTION V, CRANKCASE AND CYLINDER BLOCK; SECTION
VI, CYLINDER HEAD AND VALVES, etc.
