3. Reinstall the drain plug and torque to
21.4 N·m
(15.7 ft. lb.)
.
4. Fill the crankcase, with new oil of the proper
type, to the “F” mark on the dipstick. Refer to Oil
Type on page 6.1. Always check the level with the
dipstick before adding more oil.
Figure 6-8. Optional Remote Mounted Oil Filter.
Replace the oil filter as follows:
1. Before removing the oil filter, clean the area
around the oil filter and housing to keep dirt and
debris out of the engine. Remove the old filter. On
crankcase mounted oil filter housings, a spring
loaded inner cup allows automatic oil drainback
into the crankcase as the oil filter is removed.
Wipe off the surface where the oil filter mounts.
2. Drain the oil from the engine crankcase.
3. Allow ample time for the oil to drain from the
crankcase.
4. Reinstall the drain plug and torque to
21.4 N·m
(15.7 ft. lb.)
.
5. Apply a thin film of clean oil to the rubber gasket
on the new filter. Partial prefilling of the oil filter
is recommended.
6. Install the replacement oil filter to the filter
adapter or oil cooler. Turn the oil filter clockwise
until the rubber gasket contacts the oil filter
housing (not inner cup), then tighten the filter an
additional
3/4-1 turn
.
7. Fill the crankcase with new oil of the proper type
to the “F” mark on the dipstick.
8. 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.

5. Reinstall the oil fill cap and tighten securely.
Reinstall dipstick.
Changing Oil Filter
Replace the oil filter
seasonally (150 hours)
, or at least
every other oil change (
every 300 hours
of operation).
Always use a genuine Kohler oil filter. The oil filter on
most engines is located on top of the crankcase
between the cylinders. Some models use a remote
mounted oil filter. See Figures 6-7 and 6-8.
