P/N 0191914
CUMMINS DIESEL ENGINE
Keep the oil level between the marks on the
dipsticks.
The distance between the top and bottom
dipstick marks corresponds to about 1 qt USA
(one liter). Add oil, if needed at top of the
engines.
Add oil at the top of the engine.
NOTE: Some Cummins engines have an oil
funnel inserted into the side of the engine
block just above the oil pan. The large end
of the funnel is closed by an expansion plug.
Unscrew the handle on the plug until the
expansion plug relaxes and contracts
enough to remove from the funnel, then add
oil at the funnel.
NOTE: See the “SPECIFICATIONS” chapter
for the correct engine-oil grade and weight.
4. Fuel leaks
Visually inspect the entire length of the fuel line,
from the engine to the fuel tank, for leaks.
5. Engine coolant
Both Continental and Cummins engines are
liquid cooled. At operating temperature the
coolant should be at the HOT level. When cold,
there should be about 1 inch (2.5 cm) of
coolant in the bottom of the reservoir.
The coolant is half water and half ethylene
glycol.
To add coolant:
Turn the engine OFF at the ground-control
box MASTER KEY SWITCH.
Remove the cap from the coolant reservoir.
Add coolant and replace the cap.
6. Wiring harnesses
Inspect all the wiring harnesses, on the
machine, for loose connections, broken wires,
and frayed insulation.
