Replace the oil filter as follows:
1. Drain the oil from the engine crankcase.
2. Allow the oil filter to drain.
3. Before removing the oil filter, clean the area
around the oil filter to keep dirt and debris out of
the engine. Remove the old filter. Wipe off the
surface where the filter mounts.
4. Place a new replacement filter in a shallow pan
with the open end up. Pour new oil, of the proper
type, in through the threaded center hole. Stop
pouring when the oil reaches the bottom of the
threads. Allow a minute or two for the oil to be
absorbed by the filter material.
5. Apply a thin film of clean oil to the rubber gasket
on the new filter.
6. Install the new oil filter to the filter adapter or oil
cooler. Turn the oil filter clockwise until the rubber
gasket contacts the filter adapter or oil cooler, then
tighten the filter an additional 2/3 to 1 turn.
7. Reinstall the drain plug. Make sure it is tightened
to 13.6 N·m (10 ft. lb.) torque.

8. Fill the crankcase with new oil, of the proper type,
to the "FULL" mark on the dipstick.
9. Test run the engine to check for leaks. Stop the
engine, allow a minute for the oil to drain down,
and recheck the level on the dipstick. Make sure
oil level is up to but not over the "FULL" mark on
the dipstick.
Service Precleaner and Air Cleaner Element
These engines are equipped with a replaceable, high
density paper air cleaner element. An optional heavy-
duty air cleaner system is also available. Most engines
are also equipped with an oiled, foam precleaner which
surrounds the paper element. See Figures 12 and 13.
Check the air cleaner daily or 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: Operating the engine with loose or damaged
air cleaner components could allow unfiltered
air into the engine causing premature wear
and failure.
