Change Oil Filter
Replace the oil filter at least every other oil change
(every 200 hours of operation).
Always use a genuine
Kohler oil filter, Part No. 12 050 01.
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 oil 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. Put a drop of oil on your fingertip and wipe it on the
rubber gasket.
6. Install the replacement 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
1/2 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 “F” mark on the dipstick. Add 0.24 L (1/2 pint)
of oil for the filter capacity.
9. Start the engine and check for oil leaks. Correct
any leaks before placing the engine into service.
Check oil level to be sure it is up to but not over the
“F” mark.
Service Oil Cooler
Some engines are equipped with an oil cooler. Inspect
and clean the oil cooler every 100 hours of operation
(more frequently under severe conditions). Oil cooler
must be kept free of debris.
To service the oil cooler, clean off the outside fins with a
brush or with compressed air.
Service Precleaner and Air Cleaner Element
This engine is equipped with a replaceable, high density
paper air cleaner element. Some engines are also
equipped with an oiled, foam precleaner which
surrounds the paper element. See Figure 10.
Figure 10. Air Cleaner System Components.
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.
Service Precleaner
If so equipped, wash and reoil the precleaner every 25
hours of operation (more often under extremely dusty
or dirty conditions).
1. Loosen the cover retaining knob and remove the
cover.
2. Remove the precleaner from the paper element.
3. 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.
4. Saturate the precleaner with new engine oil.
Squeeze out all excess oil.
5. Reinstall the precleaner over the paper element.
6. Reinstall the air cleaner cover. Secure cover with
the cover retaining knob.
