LUBRICATION SYSTEM
Engine Oil
FOR ENGINE LUBRICATION, USE LUBRICATING OIL DESIGNATED FOR DIESEL SERVICE.
THESE OILS ARE CLASSIFIED ACCORDING TO THE API SPECIFICATIONS INTO SERVICE
GRADES CC, CD CF AND CG-4. THE USE OF THE IDGHEST GRADE AVAILABLE IS
RECOMMENDED. THE OIL YOU SELECT SHOULD BE USED ON A REGULAR BASIS WHEN
POSSmLE.
Engine Oil Viscosity (SAE Number)
Use oil having a viscosity best suited to the atmospheric temperature. Use of an all-season oil SAE 10W-30
with minimum viscosity change under different temperatures is suggested.
Atmospheric Temperature
68° F (20°
C)
or higher
41° F (5° C) - 68° F (20° C)
41° F (5° C) - or lower
Viscosity
SAE 30 or 10W-30
SAE 20 or 10W-30
SAE 10W-30
NOTE: Do not use engine lube oil with an SAE number greater than 30 in generator engines.
Oil Pressure
The engine's oil pressure is indicated by the oil pressure gauge.
During normal operation, the engine's oil pressure will range between 35 and 55 psi (engine hot).
NOTE: A newly started, cold engine can have an oil pressure reading upwards of 60 to 80 psi.
A warmed engine can have an oil pressure reading as low as 35 psi. These readings may also
vary depending upon the load that is placed on the generator.
Your generator set is fitted with an oil pressure sensor. Should your engine's oil pressure drop below a safe
operating pressure, the sensor will shut the engine OFF to prevent any internal damage to your generator's
engine from occurring.
Engine Oil Change (to include filter)
1. Draining the Oil Sump
Discharge the old oil through the sump drain hose (attached at the front of the engine) while the engine is
still warm. Drain the old oil completely, replace the hose in its bracket and replace the end cap securely.
Always observe the old oil as it is removed. A yellow/gray emulsion indicates the presence of water in the
oil. Although this condition is rare, it does require prompt attention to prevent serious damage. Call a com-
petent mechanic should water be present in the oil. Sea water present in the oil can be the result of a fault
in the exhaust system attached to the engine and/or a siphoning through the sea water cooling circuit into
the exhaust, filling it up into the engine (refer to the installation illustrations on pages 8 and 9).
