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.

FUEL FILTERS.

A dual-stage

filter Fig. JDIA ) is contained in a gl

sediment bowl some models have t

A drain plug is located in bott

of filter body to drain v/ater or sedim

NOTE:

The life of fuel filters depends

the amount of contamination they m

remove from the fuel. If engine misfires
