5. The grease lines will be visibly full of grease, take
care not to overfill. Grease may be seen coming
out from the main seals around the shaft, bearing
housing as evidence the lines have filled the
housing.
6. Rotate the fan drive pulley or the jockey pulley that
the grease has been applied to three or four times.
Performing this operation ensures that the grease
is spread around the internal surfaces of the
bearing.
7. If necessary, clean the residual grease from the
engine components or the area of the engine or
generator set.
Frequency that the Grease is Applied
Perkins recommends that the grease is applied at the
following service intervals:
• For engines in base load and prime power
applications - every 500 hours or 1 year
• For engines in standby applications - every 2
years (24 months)
The frequency that the grease is applied may differ
depending on the operating ambience. For example,
dirty or dusty climates, hot ambient temperatures and
prime power applications.
Installation of the Fan Drive Belts
1. Install new belts (1) over the pulleys.
2. Rotate the rod (3) to achieve an initial tension of
77 N (17 lb). The total deflection should not
exceed 16 mm (0.63 inch).
3. Tighten the locknut (4) to a torque of 120 N·m
(88.5 lb ft). Tighten bolts (5) securely.
4. Rotate the pulleys for the fan drive belts three to
four revolutions to ensure that the fan drive belts
are correctly installed. Ensure that the tension is
still 77 N (17 lb).
5. Restore the electrical supply to the engine. Install
the guards.
6. Operate the engine for 15 to 20 minutes. Refer to
Operation and Maintenance Manual, "Starting the
Engine" for the correct procedure.
7. Stop the engine. Refer to Operation and
Maintenance Manual, "Stopping the Engine" for
the correct procedure.
8. Isolate the electrical supply to the engine. Remove
the guards.
9. Loosen bolts (5) and loosen the locknut (4).
Cooling System Coolant (ELC) - Change
10. Rotate the rod (3) to achieve a final tension of
62 N (14 lb). The total deflection should not
exceed 16 mm (0.63 inch).
11. Tighten the locknut (4) to a torque of 120 N·m
(88.5 lb ft). Tighten bolts (5) securely.
12. Restore the electrical supply to the engine. Install
the guards.
Cooling System Coolant (ELC
- Change
NOTICE
Care must be taken to ensure that fluids are con-
tained during performance of inspection, mainte-
nance, testing, adjusting and repair of the product.
Be prepared to collect the fluid with suitable contain-
ers before opening any compartment or disassem-
bling any component containing fluids.
Dispose of all fluids according to Local regulations
and mandates.
NOTICE
Keep all parts clean from contaminants.
Contaminants may cause rapid wear and shortened
component life.
Clean the cooling system and flush the cooling
system before the recommended maintenance
interval if the following conditions exist:
• The engine overheats frequently.
• Foaming of the coolant is observed.
• The oil has entered the cooling system and the
coolant is contaminated.
• The fuel has entered the cooling system and the
coolant is contaminated.
Note: When the cooling system is cleaned, only
clean water is needed when the Extended Life
Coolant (ELC) is drained and replaced.
Note: Inspect the water pump and the water
temperature regulator after the cooling system has
been drained. This inspection is a good opportunity
to replace the water pump, the water temperature
regulator, and the hoses, if necessary.
