Service Paper Element
NOTE:
Refer to the
Attachments & Accessories
table
found on page 32 of this manual for the proper air filter.
The paper element should be replaced at least every 
100 hours of operation. Replace more frequently if the 
tractor is operated under extremely dusty conditions.
IMPORTANT:
Do not wash the paper element or use
pressurized air, as this will damage the element.
Examine the element and discard if dirt and/or damage 
is present.
NOTE:
Handle new elements carefully; do not use if
the sealing surfaces are damaged.
•
Clean any dirt or debris from the air cleaner base 
and cover.
•
Check the air cleaner base. Make sure it is secured 
and not damaged. Also check the air cleaner cover 
for damage or improper fit. Replace all damaged air 
cleaner components.
Air Filter Installation
•
Carefully Install the element (with precleaner) on 
the base and secure it with the wing nut.
•
Position the air cleaner cover over the base and 
hook the clasps behind the tabs on the base. Refer 
to Figure 19.
•
Push the clasps inward toward the cover to lock 
them in the closed position. 
Spark Plug
Every 100 hours of operation, remove each spark 
plug, check its condition, and reset the gap or replace 
with a new plug as necessary. 
NOTE:
Refer to the
Attachments & Accessories
table
found on page 32 of this manual for the proper spark
plug type.
•
Lift the tractor’s hood and locate the spark plug 
wires on each side of the engine.
•
Carefully pull the spark plug wire boots off of the 
spark plugs.
•
Before removing the spark plug, clean the area 
around the base of the plug to keep dirt and debris 
out of the engine.
•
Using a spark plug socket, remove the spark plugs 
and check their condition. 
•
Replace a plug if worn or damaged. Clean minor 
carbon deposits from the electrode using a soft wire 
brush. Check and re-set the gap as instructed in the 
following steps.
NOTE:
Do not clean the spark plug in a machine
using abrasive grit. Some grit could remain in the spark
plug and enter the engine causing extensive wear and
damage.
•
Check the gap using a feeler gauge and adjust, if 
necessary, by carefully bending the ground 
electrode. See Figure 20. Set the spark plug gap to 
0.75 mm (0.030 in.).

•
Reinstall the spark plugs into the cylinder heads. 
Torque the spark plug to 22 N·m (16 ft. lb.).
•
Place the spark plug wire boots over the spark 
plugs and press until you feel the plug wire 
connectors snap over the terminal of the spark 
plugs.
Fuel Filter and Pump
WARNING:
Do not replace the fuel filter or
pump when engine is hot.
The engine is equipped with an inline fuel filter and fuel 
pump located on the right side of the engine.
Visually inspect the filter periodically for a build-up of 
residue inside the filter body, and for a dirty element 
which can be indicated by discoloration. Replace the 
fuel filter when dirty.
The fuel pump can not be disassembled. If the fuel 
pump fails, replace it with a new one.
NOTE:
If necessary, remove the tractor’s right-hand
side panel as instructed on page 20 before changing
the engine’s fuel filter.
