• After the oil has finished draining, push the oil drain
valve back in, rotate it clockwise to lock the valve
closed and re-cap the end of the oil drain valve to
keep debris from entering the drain port.
IMPORTANT: Always change the oil filter when
performing an oil change on your tractor’s engine.
Changing the Oil Filter
After draining the oil, proceed as follows:
NOTE: Refer to the Attachments & Accessories table
found on page 28 of this manual for the proper oil filter.
• Before removing the old oil filter, clean around its
base to prevent debris from entering the crankcase.
• Grasp the oil filter and remove it from the oil cooler/
filter adapter by turning it counterclockwise. See
Figure 17.
Figure 17
• Place a new replacement filter in a shallow pan with
the open end up and pour new oil of the proper type
(see chart on page 18), in through the threaded
center hole.
IMPORTANT: Stop pouring when the oil reaches the
bottom of the threads and allow a minute or two for the
oil to be absorbed by the filter material.
• Put a drop of oil on your fingertip and apply a light
coating to the gasket of the new oil filter.
• Install the replacement oil filter on the engine by
turning it clockwise onto the filter adapter until the
rubber gasket makes contact with the base. Tighten
the filter an additional 1/2 turn after the gasket first
makes contact.
Re-filling the Crankcase with Oil
IMPORTANT: The engine (w/oil filter) has a capacity of
2.1 qts. (2.0 liters). Never overfill the engine crankcase.
NOTE: For the proper oil type, refer to the chart on
page 18 of this manual.
• Clean the area around the oil fill tube to prevent
debris from entering the crankcase.
• Slowly pour oil into the fill tube. Fill the crankcase
until the oil level reaches the full (F) mark on the
dipstick (Refer to Figure 15).
• Reinstall the oil fill cap/dipstick securely into the oil
fill tube.
IMPORTANT: The oil fill cap/dipstick must be installed
securely onto the tube at all times when the engine
is operating. Severe engine damage could result from
a failure to do so.
• Start the tractor engine and allow it to run for thirty
seconds, then stop the engine and remove the
ignition key.
• Check the oil level and add oil if necessary. Do not
overfill the engine crankcase.
• Examine the area around the base of the oil fill
tube, the oil filter adapter, and the oil drain valve for
leaks before operating the tractor.
IMPORTANT: If leaks are present, have your engine
serviced by your Cub Cadet dealer before operating the
tractor.
Cleaning the Oil Cooler
Inspect and clean the oil cooler every 25 hours of
operation. The oil cooler must be kept free of debris.
Clean off the outside cooling fins with a brush or with
compressed air. Refer to Figure 17.
Air Filter
The engine is equipped with a replaceable, high density
paper air cleaner element and an oiled, foam
precleaner which surrounds the paper element. Always
examine the air cleaner before starting the engine.
Check for a buildup of dirt and debris around the air
cleaner system. Keep this area clean. Also check for
loose or damaged components. Replace all bent or
damaged air cleaner components.
NOTE: Starting the tractor with loose or damaged air
cleaner components could allow unfiltered air into the
engine causing premature wear and failure.
Precleaner
Wash and re-oil the precleaner every 25 hours of
operation (more often under extremely dusty or dirty
conditions).
• Loosen the air cleaner cover knob and remove the
cover.
• Remove the precleaner.
• Wash the precleaner in warm water with detergent.
Rinse the precleaner thoroughly until all traces of
detergent are eliminated. Squeeze out excess
water (do not wring). Allow the precleaner to air dry.
• Saturate the precleaner with new engine oil.
Squeeze out all excess oil.
