Lubrication
The ability of a drive axle to deliver
quiet, trouble-free operation over a

obtained by following the dir-
recommendations from Dana.
upon the use of good quality gear
lubricant in correct quantity. The

The following lubrication instruc-
tions represent the most current
Approved Lubricants
Approved Lubricants - General:
Gear lubricants acceptable under
military specification (MILSPEC)
MIL-L-2105D (Lubricating Oils,
Gear, Multipurpose) are approved
for use in Spicer Drive Axles.
The MIL-L-2105D specification
defines performance and viscosity
requirements for multigrade oils.
It supersedes both MIL-L-2105B,
MIL-L-2105C and cold weather
specification MIL-L-10324A. This
specification applies to both
petroleum-based and synthetic-
based gear lubricants if they
appear on the most current
"Qualified Products List "
(QPL-2105) for MIL-L-2105D.
NOTE: The use of separate oil
additives and/or friction modifiers
are not approved for use in Spicer
Drive Axles.
Approved Lubricants - Synthetic
based: Synthetic-based gear
lubricants exhibit superior thermal
and oxidation stability, and
generally degrade at a lower rate
when compared to petroleum-
based lubricants. The performance
characteristics of these lubricants
include extended change intervals,
improved fuel economy, better
extreme temperature operation,
reduced wear and cleaner
component appearance. The family
of Spicer gear lubricants represents
a premium quality synthetic lube
which fully meets or exceeds the
requirements of MIL-L-2105D. These
products, available in both 75W-90
and 80W-140, have demonstrated
superior performance in com-
parison to others qualified under
the MILSPEC, as demonstrated by
extensive laboratory and field
testing.
Lube Sampling and Condition
Monitoring: For information,
contact your local Dana represen-
tation at phone numbers listed on
the back cover of this manual.
Makeup Lube: Maximum amount of
non-synthetic makeup lube is 100%.
Viscosity/Ambient Temperature
Recommendations: The following
chart lists the various SAE Grades
covered by MIL-2105D and the
associated ambient temperature
range for each. Those SAE Grades
shown with an asterisk (*) are
available in the Spicer family of
synthetic gear lubricants.
The lowest ambient temperatures
covered by this chart are -40 o F and
-40 o C. Lubrication recommenda-
tions for those applications which
consistently operate below this
temperature range, must be
obtained through the Dana.
Grade Ambient Temperature Range
75W -40 o F to -15 o F (-40 o C to -26 o C)
75W-80 -40 o F to 80 o F (-40 o C to 21 o C)
75 W-90* -40 o F to 100 o F (-40 o C to 38 o C)
75 W-140 -40 o F and above (-40 o C and above)
80W-90 -15 o F to 100 o F (-26 o C to 38 o C)
80W-140* -15 o F and above (-26 o C and above)
85 W-140 10 o F and above (-12 o C and above)
