Inspection
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
Spicer Drive Axles. The MIL-
L-2105D specification defines performance and viscosity re-
quirements 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
Spicer 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
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 80/W-
140, have demonstrated superior performance in comparison
to others qualified under the MILSPEC, as demonstrated by ex-
tensive laboratory and field testing. For a complete list of
Spicer® approved synthetic lubricants contact your local
Spicer representative. See back cover of this manual for appro-
priate phone number.
Makeup Lube: Maximum amount of non-synthetic makeup
lube is 10%.
Viscosity/Ambient Temperature
Recommendations
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 con-
tacting your local Spicer representative.
*Available in the
Spicer family of synthetic gear lubri-
cants.
