Spicer Tandem Drive Axle Dual Range & Double Planetary 34,000-45,000 lbs - Manual (Page 11)

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 lubricant in correct quantity.
The most satisfactory results can be obtained by following
the directions contained in this manual.
The following lubrication instructions represent the most
current recommendations from the Axle & Brake Division of
Dana Corporation.
Approved Lubricants
General-Gear
lubrications 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 super-
sedes both MIL-L-21 056, MIL-L-2105C and cold weather
specification MlL-L-l 0324A. This specification applies to
both petroleum-based and synthetic based gear lubricants
if they appear on the most current “Qualified Products List”
(QPL-2105) forMIL-L-2105D.
Note: The use of separate oil additives and/or friction
modifiers are not approved in 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
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 80 W-1 40, 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 Spicerr ® approved syn-
thetic lubricants contact your local Spicer representative. See
back cover of this manual for appropriate phone number.
Makeup Lube-Maximum amount of non-synthetic makeup
lube is 100/o.

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
applications which consistently operate below this tempera-
ture range, must be obtained through the Dana Corpora-
tion by contacting your local Spicer representative.
Grade Ambient Temperature Range
75W -40 o F to -15°F (-40 o C to -26 o C)
75W-80 -40°F to 80 o F (-40°C to 21 o C)
75W-90* -40 o F to 100 o F (-40 o C to 38 o C)
75W-140 -40°F and above (-40 o C and above)
80W-90 -15 0 F to 100 o F (-26°C to -38 o C)
80W-140* -15 0 F and above (-26°C and above)
85W-140 10 o F and above (-12°C and above)
Lube Change Intervals
This product combines the latest manufacturing and part
washing technology.
When filled with an approved
synthetic lubricant at the factory, the initial drain is not
required.
Change the lubricant within the first 5,000 miles of
operation when not using a approvedsynthetic
lubricant in either a new axle or after a carrier
head replacement.
Base subsequent lubricant changes on
a combination of the following chart and user assessment
of the application and operating environment.
Severe Service Lubrication Change Intervals -
Severe
service applications are those where the vehicle consis-
tently operates at or near its maximum GCW or GVW
ratings, dusty or wet environments, or consistent operation
on grades greater than 8%. For these applications, the
ON/OFF HIGHWAY portion of the chart should be used.
Typical applications are construction, logging, mining and
refuse removal.
Note:
Remove metallic particles from the magnetic filler
plug and drain plugs. Clean or replace the breather at each
lubricant change.
