• 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, and wiring harnesses.
• 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
cannot be calibrated.
Aftertreatment System
Check the condition of the coolant lines, Diesel
Exhaust Fluid (DEF) lines, and electrical
connections. Check that all clamps, clips, and tie-
wraps are secure and in good condition. Check that
the DEF filler cap is secure and that the cap is clean
and free from dirt.
Check the level of DEF in the tank is adequate for
operational purpose, if necessary fill the DEF tank.
