Danger

highly flammable and explosive. A fire or
explosion from fuel can burn you and others and
can cause property damage.
• Use a funnel and fill the fuel tank outdoors, in
an open area, when the engine is off and is cold.
Wipe up any fuel that spills.
• Do not fill the fuel tank completely full. Add fuel
to the fuel tank until the level is to the bottom of
the filler neck.
• Never smoke when handling fuel, and stay away
from an open flame or where fuel fumes may be
ignited by a spark.
• Store fuel in a clean, safety-approved container
and keep the cap in place.
3. Slide hose clamps onto ends of fuel lines. Push fuel
lines onto fuel filter and secure them with hose clamps.
Be sure arrow on side of filter points toward the
injection pump.
Fuel Lines and Connections
Check lines and connections every 400 hours or yearly,
whichever comes first. Inspect for deterioration, damage or
loose connections.
Servicing the Alternator Belt
Check the alternator belt tension every 200 hours.
1. Check tension by depressing belt midway of span with
18 lb of force. Belt should deflect 3/8 in. to 1/2 in. If
deflection is incorrect, proceed to step 2. If correct,
continue operation.
2. Loosen bolt securing brace to engine and bolt securing
alternator to brace (Fig. 40).
3. Insert pry bar between alternator and engine and pry out
on alternator.
4. Hold alternator in position after proper belt tension
setting is achieved and tighten alternator and brace bolts
to secure adjustment.
To Replace Belt:
1. Loosen bolts securing brace to engine and alternator to
brace (Fig. 40).
