Lube Change Intervals
This product combines the latest manufacturing and part washing technology. When filled with an
Spicer 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
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 service 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 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.
Changing Lube
Draining
Drain when the lube is at normal operating temperature. It will run freely and minimize the time necessary to fully drain the axle.
Unscrew the magnetic drain plug on the underside of the axle housing and allow the lube to drain into a suitable container. Inspect
drain plug for large quantities of metal particles. After initial oil change, these are signs of damage or extreme wear in the axle,
and inspection of the entire unit may be warranted. Clean the drain plug and replace it after the lube has drained completely.
Axles with Lube Pump: Remove the magnetic strainer from the power divider cover and inspect for wear material in the same
manner as the drain plug. Wash the magnetic strainer in solvent and blow dry with compressed air to remove oil and metal parti-
cles.
Exercise care to direct compressed air into safe area. Wear safety glasses.
