• The guards must be in the correct place. Repair
damaged guards or replace missing guards.
• Wipe all caps and plugs before the engine is
serviced to reduce the chance of system
contamination.
NOTICE
For any 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 flu-
id 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 is a fire
hazard. Remove the accumulated grease and oil. Re-
fer to this Operation and Maintenance Manual, "En-
gine - Clean" for more information.
• Ensure that the cooling system hoses are correctly
clamped and that the cooling system hoses are
tight. Check for leaks. Check the condition of all
pipes.
• Inspect the water pump for coolant leaks.
Note: The water pump seal is lubricated by the
coolant in the cooling system. It is normal for a small
amount of leakage to occur as the engine cools down
and parts contract.
Excessive coolant leakage may indicate the need to
replace the water pump. Remove the water pump.
Refer to Disassembly and Assembly, "Water Pump -
Remove and Install". For more information, consult
your Perkins dealer or your Perkins distributor.
• Inspect the lubrication system for leaks at the front
crankshaft seal, the rear crankshaft seal, the oil
pan, the oil filters, and the rocker cover.
• Inspect the piping for the air intake system and the
elbows for cracks and for loose clamps. Ensure
that hoses and tubes are not contacting other
hoses, tubes, wiring harnesses.
• Ensure that the areas around the rotating parts are
clear.
• Inspect the alternator belts and any accessory
drive belts for cracks, breaks, or other damage.
• Inspect the wiring harness for 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.
High-Pressure Fuel Lines
Contact with high pressure fuel may cause fluid
penetration and burn hazards. High pressure fuel
spray may cause a fire hazard. Failure to follow
these inspection, maintenance and service in-
structions may cause personal injury or death.
After the engine has stopped, you must wait for 10
minutes to allow the fuel pressure to be purged from
the high-pressure fuel lines before any service or
repair is performed on the engine fuel lines. If
necessary, perform minor adjustments. Repair any
leaks from the low-pressure fuel system and from the
cooling, lubrication, or air systems. Replace any high-
pressure fuel line that has leaked. Refer to
Disassembly and Assembly Manual, "Fuel Injection
Lines - Install".
When there is not an alternative course of action and
the engine must be in operation while it is inspected,
always use the correct inspection procedure to avoid
a fluid penetration hazard. Refer to Operation and
Maintenance Manual, "General hazard Information".
Visually inspect the high-pressure fuel lines for
damage or signs of fuel leakage. Replace any
damaged high-pressure fuel lines or high-pressure
fuel lines that have leaked.
Ensure that all clips on the high-pressure fuel lines
are in place and that the clips are not loose.
• Inspect the rest of the fuel system for leaks. Look
for loose fuel line clamps.
• Drain the water and the sediment from the fuel
tank daily 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. Check for any loose tie-wraps or missing
tie-wraps.
• 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.
