Lubrication
Lube Change Intervals
This product combines the latest manufacturing and part
washing technology. When filled with
-«ˆViÀ
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
-«ˆVer approved synthetic lubri-
cant in either a new axle or after a carrier head
replacement. Base subsequent lubricant changes on a com-
bination 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.
For additional lubrication information, see TCMT-0021.
