4. Install the replacement oil filter to the filter adapter,
turn the oil filter clockwise until the rubber gasket
contacts the filter adapter, then tighten the filter an
additional 3/4 turn (Figure 24).
5. Fill the crankcase with the proper type of new oil;
refer to Servicing the Engine Oil.
6. Run the engine for about 3 minutes, stop the engine,
and check for oil leaks around the oil filter and drain
valve.
7. Check the engine oil level and add oil if needed.
8. Wipe up any spilled oil.
Servicing the Spark Plugs
Service Interval: Every 100 hours
Ensure that the air gap between the center and side
electrodes is correct before installing the spark plug.
Use a spark plug wrench for removing and installing the
spark plugs and a gapping tool/feeler gauge to check and
adjust the air gap. Install a new spark plugs if necessary.
Type: Champion® RCJ8Y or equivalent Air Gap:
0.030 inch (0.75 mm)
Removing the Spark Plugs
1. Disengage the PTO and set the parking brake.
2. Stop the engine, remove the key, and wait for all
moving parts to stop before leaving the operating
position.
3. Disconnect the wires from the spark plugs
(Figure 25).

4. Clean around the spark plugs to prevent dirt from
falling into the engine and potentially causing
damage.
5. Remove the spark plugs and the metal washers.
Checking the Spark Plugs
1. Look at the center of the spark plugs (Figure 26).
If you see light brown or gray on the insulator, the
engine is operating properly. A black coating on the
insulator usually means that the air cleaner is dirty.
2. If needed, clean the spark plug with a wire brush to
remove carbon deposits.

Important:
Always replace the spark plugs
when it has worn electrodes, an oily film on it,
or has cracks in the porcelain.
3. Check the gap between the center and side electrodes
(Figure 26). Bend the side electrode (Figure 26) if
the gap is not correct.
Installing the Spark Plugs
1. Install the spark plugs and the metal washer. Ensure
that the air gap is set correctly.
2. Tighten the spark plugs to 16 ft-lb (22 N-m).
3. Connect the wires to the spark plugs (Figure 26).
