Run the engine for a few minutes to
allow the oil in the crankcase to warm
up. Warm oil will flow more freely and
carry away more of the engine
sediment which may have settled at
the bottom of the crankcase. Use care
to avoid burns from hot oil. While the
engine oil is warm, proceed as follows:
Note: A length of flexible tubing is
supplied with the tractor and should be
used to drain the engine oil.
• Place the tractor on a level surface
and engage the parking brake. Stop
the tractor engine and remove the
ignition key.
• Clean around the base of the oil
filter, the oil filler cap, and the
dipstick tube to prevent debris from
entering the crankcase. See Figure
26.
• Remove the dipstick.
• Attach the flexible tubing to the
drain valve. Place an appropriate
container below the open end of the
tubing to collect the old oil.
• To open the drain valve, turn hex
end counterclockwise until it stops.
• Remove the filter by turning it
counterclockwise using an
automotive type filter wrench to
loosen.
• Allow the old oil to completely drain
from the engine crankcase into the
container below.
• Close the drain valve.
• Remove the flexible tubing from the
drain valve. Clean the tubing and
store in a safe place for future use.
• Clean the drain valve.
• Apply a light coating of clean oil on
the gasket of the new oil filter.
Thread the filter on by hand until
the gasket contacts the oil filter
adapter, then tighten the filter an
additional 1/2 to 3/4 turn.
• Refill the crankcase with the
quantity and type of appropriate oil.
• Check oil level and make sure that
oil filler cap, dipstick and drain valve
are in place and closed.
Sparkplugs
WARNING: To avoid possi-
ble injury, be sure the engine
is off and has cooled before
making any adjustments or
repairs.
Remove all dirt from around the spark
plug before removing.
To remove the spark plugs, always
use a spark plug wrench. Check the
gap after every 100 hours of
operation.
Replace a defective plug with a new
plug. Set the spark plug gap at .026
inch. Tighten the plug to 17 ft-lbs. See
your authorized dealer for the correct
replacement plug.
Changing Fuel Filter
WARNING: Do not replace
the fuel filter when engine is
hot.
The engine is equipped with an in-line
fuel filter. 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.
