Lube Change Intervals
This product combines the latest manufacturing and part
washing technology.
Note: When filled with an
Spicer approved synthetic lubricant at
the factory, the initial drain is not required.
Note: Change the lubricant within the first 5,000 miles of oper-
ation when not using a
Spicer approved synthetic
lubricant in either a new axle or after a carrier head re-
placement.
Base subsequent lubricant changes on a combination of the
following chart and user assessment of the application and op-
erating environment.
Severe Service Lubrication Change Intervals: Severe service
applications are those where the vehicle consistently operates
at or near its maximum GCW or GVW ratings, dusty or wet en-
vironments, 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: Clean metallic particles from the magnetic filler plug and
drain plugs at each maintenance interval. Clean or re-
place the breather yearly to avoid lube contamination due
to water ingestion.
