Lubrication
Lubrication
The ability of a drive axle to deliver quiet, trouble-free operation
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 Axle & Brake Division of Dana
Corporation.
Approved Lubricants
General -Gear lubrications acceptable under military specifica-
tion (MILSPEC) MIL-L-2105D (Lubricating Oils, Gear, Multi-
purpose) 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 su-
perior thermal and oxidation stability, and generally degrade at
a lower rate when compared to petroleum-based lubricants.
The performance characteristics of these lubricants include ex-
tended change intervals, improved fuel economy, better ex-
treme temperature operation, reduced wear and cleaner
component appearance. The family of Dana
Spicerª 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 80/W-140, have
demonstrated superior performance in comparison to others
qualified under the MILSPEC, as demonstrated by extensive
laboratory and field testing. For a complete list of
Spicer¨
approved synthetic lubricants contact your local Dana repre-
sentative. 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 lubricants.
The lowest ambient temperatures covered by this chart are
-40°F and -40°C. Lubrication recommendations for those ap-
plications which consistently operate below this temperature
range, must be obtained through Dana Corporation by contact-
ing your local Dana representative.
* Available in the
Spicer family of synthetic gear lubri-
cants.
