• Use No. 2 diesel fuel. Use No. 1 diesel fuel if the
temperature is below 15° F (-10°C).
• The fuel tank capacity is approximately 10.6 gal.
Do not overfill.
Bleeding the Fuel System
WARNING: Do not bleed the fuel system
when the engine is hot.
Air must be bled from the fuel system when the fuel
filter or fuel lines are removed; the fuel tank is
completely emptied; or the tractor has not been used
for a long period of time.
• Fill the fuel tank with No. 2 diesel fuel and make
certain the shut-off valve on the fuel filter is open.
• Loosen the air vent cock on the injection pump
two or three turns by hand, then start to turn the
engine over. See Figure 52.
Figure 52
• When there are no more air bubbles in the fuel
line, tighten the air vent cock.
Servicing the Fuel Filter
WARNING: When servicing the fuel fil-
ter element, take all precautions to
prevent dust or dirt from entering the
fuel system. Contaminants will cause
premature wear and/or malfunction of
the injection pump and injection
nozzles.
The fuel filter should be cleaned after every 100
hours of operation, and replaced after every 400
hours.
• Make certain the area is free of dust and dirt.
• Close the shut-off valve on the fuel filter. See
Figure 53.

• Unscrew the retaining ring and remove the ring
and fuel filter bowl from the filter. Use care not to
lose the O-ring and spring. See Figure 54.

• Flush the bowl out with clean diesel fuel.
• Remove the element and either dip it into a con-
tainer of clean diesel fuel to clean it, or replace it
with a new element.
• Install the new, or cleaned, element onto the fil-
ter body.
• Install the filter bowl and retaining ring over the
element, and tighten the retaining ring to secure.
• Bleed the air from the fuel system using the air vent
cock on the injection pump. Refer to Figure 52.
Checking the Fuel Lines
WARNING: The fuel line hoses are
subject to wear and natural aging. A
leaking fuel line may allow fuel to come
into contact with sources of ignition, and
could cause a fire.
The condition of the fuel line hoses and clamps
should be checked every 100 hours or six months
(whichever occurs first), and they should be replaced
every two years. Refer to Figure 52.
