3. Apply a thin coat of new oil to the rubber gasket on
the replacement filter (Figure 34).
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 34).
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.

Servicing the Spark Plugs
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 35).

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
Service Interval: Every 100 hours
1. Look at the center of the spark plugs (Figure 36).
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.

2. Side electrode
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 36). Bend the side electrode (Figure 36) 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 36).
