Water Pump - Inspect - Perkins XGA 1600 Series Operation And Maintenance Manual

SEBU8455
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
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 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 the cooling lines are properly clamped
and that the cooling lines are tight. Check for leaks.
Check the condition of all pipes.
•
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 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 valve cover.
• Inspect the fuel system for leaks. Look for loose
fuel line clamps or for loose fuel line tie-wraps.
•
Inspect the piping for the air inlet system and the
elbows for cracks and for loose clamps. Ensure
that hoses and tubes are not contacting other
hoses, tubes, wiring harnesses, etc.
•
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 ECM to the cylinder head 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 that are cracked. Replace any gauge that
can not be calibrated.

Water Pump - Inspect

A failed water pump might cause severe engine
overheating problems that could result in the following
conditions:
•
Cracks in the cylinder head
•
A piston seizure
•
Other potential damage to the engine
Visually inspect the water pump for leaks. If any
leaking is observed, replace the water pump seal
or the water pump assembly. Refer to the Service
Manual for the disassembly and assembly procedure.
Note: Refer to the Service Manual or consult your
Perkins distributor if any repair is needed or any
replacement is needed.
