Walk-Aro und Inspection
SMCS Code: 1000-040
Personal injury or death can result from improper
troubleshooting and repair procedures.
The following troubleshooting and repair proce-
dures should only be performed by qualified per-
sonnel famil
iar with this equipment.
Inspect the En
gine for Leaks an d
for Loose C onnections
A walk-around inspection should only take a few
minutes. When the time is taken to perform these
checks, cost
ly 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 build
up. Make repairs, as needed:
•
The guards must be in the proper place. Repair
damaged gua
rds or replace missing guards.
•
Wipe all caps and plugs before the engine is
serviced in
order to reduce the chance of system
contamination.
NOTICE
For any type of leak (coolant, lube, or fuel) clean up the
fluid. If le
aking 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.
Check for leaks. Check the condition of all pipes.
•
Inspect the water pump 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 cool
ant leakage may indicate the need
to replace the water pump seal. For the removal of
water pump and the installation of water pump and/or
seals, refer t
o the Service Manual for the engine or
consult your Caterpillar dealer.
•
Inspect the l
ubrication system for leaks at the front
crankshaft seal, the rear crankshaft seal, the oil
pan, the oil filters and the valve cover.
•
Inspect the Closed Crankcase Ventilation (CCV)
filter,ifequipped.Iftherestrictionindicatoris
visible, ser
vice the CCV.
•
Inspect t he fuel system for leaks. Look for loose
fuel line cla
mps.
•
Inspect the piping for the air inlet system and the
elbows for c
racks and for loose clamps.
•
Inspect the alternator belt and the accessory drive
belts for cr
acks, breaks or other damage.
Belts for multiple groove pulleys must be replaced as
matched set
s. 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 bel
t could cause the belt to break.
•
Drain the water and the sediment from fuel tanks
onadailyb
asis in order to ensure that only clean
fuel enters the fuel system.
•
Inspect th
e 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. Ch
eck 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 that are cracked. Replace any gauges that
can not b
ecalibrated.
Inspect
the Generator
Refer to Safety Section, “Generator Isolating for
Mainten
ance” for information regarding the procedure
to safely isolate the generator.
