Change Oil and Filter, Service Oil Cooler
Change Oil
Change oil after every 100 hours of operation (more
frequently under severe conditions). Refill with
service class SG, SH, SJ or higher oil as specified in the
Viscosity Grades table (Figure 3) on page 5.
Change the oil while the engine is still warm. The oil
will flow more freely and carry away more
impurities. Make sure the engine is level when filling,
checking, and changing the oil.
Change the oil as follows (see Figures 8 and 9):
1. To keep dirt, debris, etc., out of the engine, clean
the area around the oil fill cap/dipstick before
removing it.
2. Remove one of the oil drain plugs, oil fill cap, and
dipstick. Be sure to allow ample time for complete
drainage.
3. Reinstall the drain plug. Make sure it is tightened
to 13.6 N·m (10 ft. lb.) torque.
4. Fill the crankcase, with new oil of the proper
type, to the "F" mark on the dipstick. Refer to Oil
Type on page 5. Always check the level with the
dipstick before adding more oil.
5. Reinstall the oil fill cap and tighten securely.
Reinstall dipstick.
NOTE: To prevent extensive engine wear or
damage, always maintain the proper oil
level in the crankcase. Never operate the
engine with the oil level below the "L"
mark or over the "F" mark on the
dipstick.

Change Oil Filter
Replace the oil filter at least every other oil change

Kohler oil filter. Use chart below to determine part
number to order.
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. Apply a thin film of clean oil to the rubber gasket
on the new filter.
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 3/4 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 "F" mark on the dipstick.
