MAINTENANCE / ADJUSTMENTPeriodicServiceLubricationThe ability of a drive axle to deliverquiet, trouble-free operation over aperiod of years is largely dependentupon the use of good quality gearlubricant in correct quantity. TheApproved Lubricantsmost satisfactory results can beobtained by following the dirrecommendationsfromections contained in this book.The following lubrication instructionsrepresent the most currentDana.Section 2Approved Lubricants - General:Gear lubricants acceptable undermilitary specification (MILSPEC)MIL-L-2105D (Lubricating Oils,Gear, Multipurpose) are approvedfor use in Spicer Drive Axles.The MIL-L-2105D specificationdefines performance and viscosityrequirements for multigrade oils.It supersedes both MIL-L-2105B,MIL-L-2105C and cold weatherspecification MIL-L-10324A. Thisspecification applies to bothpetroleum-based and syntheticbasedgear lubricants if theyappear on the most current"Qualified Products List "(QPL-2105) for MIL-L-2105D.NOTE: The use of separate oiladditives and/or friction modifiersare not approved for use in SpicerDrive Axles.Approved Lubricants - Syntheticbased: Synthetic-based gearlubricants exhibit superior thermaland oxidation stability, andgenerally degrade at a lower ratewhen compared to petroleumbasedlubricants. The performancecharacteristics of these lubricantsinclude extended change intervals,improved fuel economy, betterextreme temperature operation,reduced wear and cleanercomponent appearance. The familyof Spicer gear lubricants representsa premium quality synthetic lubewhich fully meets or exceeds therequirements of MIL-L-2105D. Theseproducts, available in both 75W-90and 80W-140, have demonstratedsuperior performance in comparisonto others qualified underthe MILSPEC, as demonstrated byextensive laboratory and fieldtesting.Lube Sampling and ConditionMonitoring: For information,contact your local Dana representationat phone numbers listed onthe back cover of this manual.Makeup Lube: Maximum amount ofnon-synthetic makeup lube is 100%.Viscosity/Ambient TemperatureRecommendations: The followingchart lists the various SAE Gradescovered by MIL-2105D and theassociated ambient temperaturerange for each. Those SAE Gradesshown with an asterisk (*) areavailable in the Spicer family ofsynthetic gear lubricants.The lowest ambient temperaturescovered by this chart are -40 o F and-40 o C. Lubrication recommendationsfor those applications whichconsistently operate below thistemperature range, must beobtained through the Dana.GradeAmbient Temperature Range75W -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)6
