Lubricant Specifications
Lubricant Information
Some classifications and abbreviations we use in
this section follow S.A.E. (Society of Automotive
Engineers) J754 nomenclature and others follow
S.A.E. J183.
All MIL specifications are U.S.A. Military.
Recommended oil viscosities are given in the
"Lubricant Viscosities" chart later in this section of
the manual.
Greases are classified according to the National
Lubricating Grease Institute (NLGI) based on ASTM
D217-68 worked Penetration characteristics which
give a defined consistency number.
Engine Oil (DEO and EO)
The following oil specifications provide guidelines for
the selection of commercial products :
.Gasoline/LP Engine : API SJ
.Diesel Engine : API CH4 or ACEA E5
NOTICE
Failure to follow the oil recommendations can cause
shortened engine life due to carbon deposits or
excessive wear.
Consult the EMA Lubricating Oils Data Book for a
listing of oil brands.
NOTE: The percentage of sulfur in the fuel will
affect the engine oil recommendations. For
fuel sulfur effects, the Infrared Analysis or
the ASTM D2896 procedure can be used to
evaluate the residual neutralization
properties of engine oil. The sulfur products
formation depends on the fuel sulfur content,
oil formulation, crankcase blowby, engine
operating conditions and ambient
temperature.
Hydraulic Oil (HYDO)
The following commercial classifications can be
used in the hydraulic system.
z ISO 6743/4 HM
z AFNOR NFE 48-603 HM
z DIN 51524 TEIL 2 H-LP
z HAGGLUNDS DENISON HFO-HF2
z CINCINNATI P68, 69, 70
Viscosity : ISO VG32
Industrial premium hydraulic oils that have passed
the Vickers vane pump test (35VQ25).
These oils should have antiwear, antifoam, antirust
and antioxidation additives for heavy duty use as
stated by the oil supplier. ISO viscosity grade of 32
would normally be selected.
Transmission Oil (TDTO)
NOTICE
These oils are formulated for transmissions and
drive trains only, and should not be used in engines.
Shortened engine life will result.
NOTE: Multi-grade oils are not blended by
DOOSAN for use in transmissions.
Multi-grade oils which use high molecular
weight polymers as viscosity index
improvers lose their viscosity effectiveness
by permanent and temporary shear of the
viscosity index improver and therefore, are
not recommended for transmission and
drive train compartments.
NOTE: Failure to follow this recommendation can
cause shortened transmission life due to
material incompatibility, inadequate
frictional requirements for disk materials
and/or excessive gear wear.
Select Oil that meets below specifications.
