General Lubrication Information
The ability of a drive axle to deliver quiet, trouble-free opera-
tion over a period of years is largely dependent upon the use
of good quality gear lubrication in the correct quantity. The
most satisfactory results can be obtained by following the
directions contained in this manual.
The following lubrication instructions represent the most cur-
rent recommendations from the Commercial Vehicle Division
of Dana Corporation.
Approved Lubricants
General - Gear lubrications acceptable under military specifi-
cation (MILSPEC) MIL-L-2105D (Lubricating Oils, Gear, Mul-
tipurpose) are approved for use in Dana 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 modifi-
ers are not approved in Dana Drive Axles.
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 lubri-
cants include extended change intervals, improved fuel econ-
omy, better extreme temperature operation, reduced wear and
cleaner component appearance. The family of Dana
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
comparison to others qualified under the MILSPEC, as dem-
onstrated by extensive laboratory and field testing. For a com-
plete list of
Spicer® approved synthetic lubricants
contact your local Dana representative. See back cover of this
manual for appropriate phone number.
Makeup Lube - Maximum amount of non-synthetic makeup
lube is 10%.
Recommendations for Viscosity/Ambient
Temperature
The following chart lists the various SAE Grades covered by
MIL-L-2105D and the associated ambient temperature range
from each. Those SAE grades shown with an asterisk (*) are
available in the
Spicer family of synthetic gear lubri-
cants.
The lowest ambient temperatures covered by this chart are
-40°F and -40°C. Lubrication recommendations for those
applications which consistently operate below this tempera-
ture range, must be obtained through Dana Corporation by
contacting your local Dana representative.
* Available in the
Spicer family of synthetic gear lubri-
cants.
