REQUIREMENTS FOR PROPER OPERATION
LUBRICATION
SYSTEM
1. Engine oil
For engine lubrication, use diesel engine oil. Diesel engine oils
are classified according to the API Specifications into grades CA,
CB,
CC and CD. Anyone of them is usable, but use of CC or higher
grades prepared by well-known makers is recommended.
2. Engine oil viscosity
Use oil having viscosity best suited to the atmospheric tem-
perature. Use of an all-season oil SAEIOW-30 with minimum visco-
sity change under different temperatures is suggested.
Atmospheric temperature
Viscosity
20·C (6a·F) or higher SAE 30 or lOW-30
SAE 20 or 10W-30
S·C (41·F) or lower SAE 10W-30
3. Oil pressure
The oil pressure dur ing operation of the engine is indicated by
the oil pressure gauge.
During normal operation •••••••••••• Oil pressure will range between
50 and 70 PSI.
At the time of cranking •••••••••••• Pressure will rise proportion-
ately with speed.
4. Engine oil change
To renew engine oil, discharge old oil through the sump drain hose
attached at front of engine while engine is still warm.
Drain old oil completely, replace the hose, plug the end securely
and add fresh oil through the oil inlet port on the valve cover.
