• Inspect the lubrication system for leaks at the front
crankshaft seal, the rear crankshaft seal, the oil
pan, the oil filters and the valve cover.
• Inspect the fuel system for leaks. Look for loose
fuel line clamps.
• Inspect the piping for the air inlet system and the
elbows for cracks and for loose clamps.
• Inspect the alternator belt and the accessory drive
belts for cracks, breaks or other damage.
Belts for multiple groove pulleys must be replaced as
matched sets. If only one belt is replaced, the belt will
carry more load than the belts that are not replaced.
The older belts are stretched. The additional load on
the new belt could cause the belt to break.
• Drain the water and the sediment from fuel tanks
on a daily basis in order to ensure that only clean
fuel enters the fuel system.
• Inspect the wiring and the wiring harnesses for
loose connections and for worn wires or frayed
wires.
• Inspect the ground strap for a good connection
and for good condition.
• Inspect the engine-to-frame ground strap for a
good connection and for good condition.
• Disconnect any battery chargers that are not
protected against the current drain of the starting
motor. Check the condition and the electrolyte
level of the batteries, unless the engine is
equipped with a maintenance free battery.
• Check the condition of the gauges. Replace any
gauges which are cracked or can not be
calibrated.
