Change the oil as follows:
1. A drain plug is located on either side of the oil
sump; one is near the starter, the other is near the
oil filter. See Figures 6-4 and 6-5. Clean the area
around the most accessible oil drain plug and the
oil fill cap/dipstick.
2. Remove the selected drain plug and the oil fill
cap/dipstick.
3. Allow the oil to drain and then reinstall the
drain plug. Torque to 13.6 N·m (10 ft. lb.).
4. Fill the engine with the proper oil to the ‘‘FULL’’
mark on the dipstick. Always check the oil level
with the dipstick before adding more oil.
5. Reinstall the oil fill cap/dipstick.
Changing Oil Filter
Replace the oil filter at least every other oil change
(every 200 hours of operation). Always use a genuine
Kohler oil filter. Change the filter as follows. See
Figures 6-4 or 6-5.
1. An oil drain plug is located on either side of the
oil sump; one is next to the oil filter, the other is
next to the starter. Clean the areas around the
most accessible drain plug, the oil filter, and the
oil fill cap/dipstick.
2. Remove the selected drain plug and the oil fill
cap/dipstick.
3. Allow the oil to drain and then reinstall the
drain plug. Torque to 13.6 N·m (10 ft. lb.).
4. Remove the old filter and wipe off the filter
adapter with a clean cloth.
5. 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.
6. Apply a thin film of clean oil to the rubber gasket
on the new oil filter.
7. Install the new oil filter to the filter adapter.
Hand tighten the filter clockwise until the rubber
gasket contacts the adapter, then tighten the
filter an additional 3/4-1 turn.
8. Fill the engine with the proper oil to the “FULL”
mark on the dipstick. Always check the oil level
with the dipstick before adding more oil.
9. Reinstall the oil fill cap/dipstick.
10. Start the engine and check for oil leaks. Stop the
engine, correct any leaks, and allow a minute for
the oil to drain down, then recheck the level on
the dipstick.
Service Oil Cooler
Some engines are equipped with an oil cooler. One
style of oil cooler mounts on the engine crankcase and
has the oil filter on it. See Figure 6-6. The other style of
oil cooler is mounted on the blower housing, separate
from the oil filter. See Figure 6-7.
Inspect and clean the oil cooler every 100 hours of
operation (more frequently under severe conditions).
In order to be effective, the oil cooler must be kept free
of debris.
Figure 6-6. Crankcase Mounted Oil Cooler.
To service the crankcase mounted oil cooler, clean off
the outside fins with a brush or with compressed air.
