Lubrication
Lube Change Intervals
This product combines the latest manufacturing and part
washing technology. When filled with a Spicer-approved
synthetic lubricant at the factory, the initial drain is
not required.
Change the lubricant within the first 5,000 miles of opera-
tion when not using a Spicer-approved synthetic 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 ser-
vice applications are those where the vehicle consistently
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 HIGH-
WAY portion of the chart should be used. Typical applications
are construction, logging, mining and refuse removal.
Note: Clean metallic particles from the magnetic filler plug
and drain plugs. Clean or replace the breather yearly to
avoid lube contamination due to water ingestion.
