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.
