REQUIREMENTS FOR PROPER OPERATION
LUBRICATION SYSTEM
1.
Engine oil
For engine lubrication, use diesel engine oil.
Diesel engine oils
are classified ac-cording to the API Specifications into grades CA,
ca, 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 SAEIDW-30 with minimum visco-
sity change under different temperatures is suggested.
Atmospheric temperature
Viscosity
20'C (6S'F) or higher
SAE 30 or lOW-3D
S"C
(41"F) -
20"C
(6a"F)
SAE 20 or IOW-30
s·c
(41'F) or lower
SAE
10W-30
3. Oil pressure
The oil pressure during 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.
After refilling oil, idle the engine for several minutes and stop.
Then check the quanti ty of oil by the oil level gauge.
Fill to
but not over the high mark on the dipstick.
