How To Service The Air Filter - Figure 7
WARNING
Fuel and its vapors are extremely flammable and explosive.
Fire or explosion can cause severe burns or death.
• Never start or run the engine with the air cleaner assembly or the air filter
removed.
NOTICE: Do not use pressurized air or solvents to clean the filter. Pressurized air can
damage the filter and solvents will dissolve the filter.
See the Maintenance Chart for service requirements.
1. Open the latches (A) and remove the cover (B). See Figure 7.
2. Remove the air filter (C).
3. To loosen debris, gently tap the air filter on a hard surface. If the air filter is
excessively dirty, replace with a new air filter.
4. Install the air filter.
5. Install the cover and close the latches.
How To Replace The Fuel Filter - Figure 8
WARNING
Fuel and its vapors are extremely flammable and explosive.
Fire or explosion can cause severe burns or death.
• Disconnect battery at negative terminal (only engines with electric start.)
• Keep fuel away from sparks, open flames, pilot lights, heat, and other ignition
sources.
• Check fuel lines, tank, cap, and fittings frequently for cracks or leaks.
Replace if necessary.
• Before replacing the fuel filter, drain the fuel tank or close the fuel shut-off valve.
• Replacement parts must be the same and installed in the same position as the
original parts.
• If fuel spills, wait until it evaporates before starting engine.
If the fuel filter warning light illuminates while the engine is running, stop the engine and
drain water from fuel filter as follows:
Replace fuel filter
1. Disconnect the sensor wire (D).
2. Remove the drain plug (B) and discard the O-ring (E).
3. Remove the fuel filter (A) with a filter wrench.
4. Install a new fuel filter by hand until gasket (F) contacts the housing. Then tighten an
additional 1/3 turn.
5. Install the drain plug with new O-ring.
6. Connect the sensor wire.
7. Activate the primer pump (C) until resistance is felt.
8. Start the engine and check for leaks.
Drain water from fuel filter
1. Stop the engine.
2. Place a drain pan under the fuel filter (A) and loosen drain plug (B) approximately
one turn.
3. Water should drain from the fuel filter. If necessary, operate the primer pump (C) to
drain water, but only until fuel flows from the fuel filter.
4. Tighten the drain plug.
5. Start the engine. Make sure that the warning light is off. Check for leaks.
How To Check/Adjust The Fan Belt - Figure 9
Check Fan Belt
1. Check the condition of the fan belt (A, Figure 9). If the fan belt has cracks or is
damaged, replace with a new belt.
2. Check the tension of the fan belt. Press on the center (C) of the fan belt. If tension is
correct, the belt will move 3/8 -- 1/2 in (10 -- 12 mm) if 22 lbs (10 kg) of force is
applied to the center of the belt. If the tension is too loose, adjust as follows.
Adjust Fan Belt Tension
1. Loosen the alternator mounting bolts (D) and (E). See Figure 9.
2. Position a pry bar (F) against the alternator (G) and the side of the engine block. To
tighten the fan belt, pull on the pry bar. Temporarily tighten the alternator mounting
bolts.
3. Check the tension of the fan belt. See Check Fan Belt section. If necessary, repeat
the procedure.
4. Tighten the alternator mounting bolts.
Torque bolt (D) to 14 ft-lbs (19 Nm).
Torque bolt (E) to 45 ft-lbs (61 Nm).
Storage
WARNING
Fuel and its vapors are extremely flammable and explosive.
Fire or explosion can cause severe burns or death.
When Storing Fuel Or Equipment With Fuel In Tank
•
Store away from furnaces, stoves, water heaters or other appliances that have
pilot lights or other ignition sources because they can ignite fuel vapors.
Fuel System
Draining the fuel tank is not recommended for storage. Instead, fill the fuel tank to
prevent condensation, then add a diesel fuel micro-biocide additive to prevent bacteria
and fungi from growing in the tank. Run the engine for several minutes to circulate the
additive through the system.
Engine Oil
While the engine is still warm, change the engine oil.
