Lube Change Intervals—Axle housing
General
The initial lubricant change is one of the most
important factors in axle component life and
durability, because of the elimination of break-in
contaminants. These contaminants are primarily
metal from initial break-in wear of rotating
components, and silicon from the sand used in
manufacture of cast components.
For either a new or rebuilt drive axle, the
lubricant should be changed from both the axle
and wheel end assemblies within the first 50
hours of operation. Subsequent lubricant
changes should be based on a combination of
the intervals stated in the following chart and
user judgment based heavily on the application
and operating environment.
NOTE
: At both the initial and all subsequent
lubricant changes, Spicer recommends cleaning
the magnetic filler plug and drain plugs, and
cleaning the breather.
