Walk-Around Inspection
SMCS Code: 1000-040
Inspect the Engine for Leaks and
for Loose Connections
A walk-around inspection should only take a few
minutes. When the time is taken to perform these
checks, costly repairs and accidents can be
avoided.
For maximum engine service life, make a thorough
inspection of the engine compartment before
starting the engine. Look for items such as oil leaks
or coolant leaks, loose bolts, worn belts, loose
connections and trash buildup. Make repairs, as
needed:
•
The guards must be in the proper place. Repair
damaged guards or replace missing guards.
•
Wipe all caps and plugs before the engine is
serviced in order to reduce the chance of system
contamination.
NOTICE
Forany type of leak (coolant, lube, or fuel) clean up the
fluid. If leaking is observed, find the source and correct
the leak. If leaking is suspected, check the fluid levels
more often than recommended until the leak is found
or fixed, or until the suspicion of a leak is proved to be
unwarranted.
NOTICE
Accumulated grease and/or oil on an engine or deck is
a fire hazard. Remove this debris with steam cleaning
or high pressure water.
•
Ensure that cooling lines are properly clamped
and that cooling lines are tight. Check for leaks.
Check the condition of all pipes.
•
Check the marine transmission oil level. Refer to
the OEM specification for the marine transmission
or refer to the OEM specification for the vessel.
•
Inspect the water pumps for coolant leaks.
Note: The water pump seal is lubricated by coolant
in the cooling system. It is normal for a small amount
of leakage to occur as the engine cools down and
the parts contract.
Excessive coolant leakage may indicate the need
to replace the water pump seal. For the removal of
water pumps and the installation of water pumps
and/or seals, refer to the Service Manual for the
engine or consult your Caterpillar dealer.
•
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.
•
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 any gauges that
can not be calibrated.
