Engines are liquid cooled, in-line, four-
stroke, direct injection diesel engines.
Crankshaft rotation is counter-clock-
wise at pto flywheel end of
engine).
Fir-
ing order is 1-2-3 for three cylinder
engines; 1 3 4 2 for four cylinder
engines;
1 5 3 6 2 4
for six cylinder
engines. Cylinders are numbered from
front to rear. Models 4239T, 4276T,
6359T, 6404T, 6414T and 6466T are
equipped with turbochargers. Models
6404A and 6466A a re equipped with tur-
bocharger and intercooler.

MAINTENANCE
LUBRICATION
All Models
Recommended engine oil is SAE 5W
or SAE 5W-20 for temperatures below
-10F., SAE low or SAE lOW-30 for
temperatures between -10F. and 32F.
or SAE 30 for temperatures above
32F. API oil classification should be CD
for single viscosity oils and CC for m ulti-
viscosity oils.
Crankcase capacities for oil changes
are listed below. Due to production
changes in oil pans and the use of op-
tional oil pans on some engines, it is ad-
visable to check oil level on dipstick, as
crankcase is being filled, to prevent
underfilling or overfilling.

Manufacturer recommends renew
engine oil and oil filter after first
hours operation. Thereafter, ren
engine oil every 100 hours and oil fi
every 200 hours operation.
