Drive Axle Oil
Do not use Gear Oil in the final drives or
differentials. Gear Oil can cause seal material to fail
and possibly leak oil.
NOTE: Failure to follow the recommendation will
cause shortened life due to excessive gear
wear.
The API GL-4 specification or MIL-L-2105A oils
could be used.
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.
Lubricating Grease(MPGA)
Use Multipurpose Molybdenum Grease (MPGM) for
all lubrication points. If MPGM grease can not be
used, a multipurpose type grease which contains
3% to 5% molybdenum disulfide can be used.
NLGI NO.2 grade is suitable for most temperatures.
Use NLGI No.1 or No.0 grade for extremely low
temperature.
