parts orders and correspondence. Also, the
transmission, axles, power steering pump
chassis and other major components are
identified by serial numbers.

The engine serial and model numbers are laser
etched on the cylinder block (as viewed from the
flywheel end) on the left side just below the fire
deck and above the cast-in Detroit Diesel logo
(Fig. 1).

In addition, option plates made of laminated
paper are located on the rocker cover (starter
side). The engine serial and model number and
a list of the optional engine equipment are
written on the option plate. Refer to this
