To ensure proper lubrication and operating temperature,
correct lubricants and lubricant levels must be obtained.
RECOMMENDED LUBRICANTS
Petroleum based or synthetic based hypoid gear lubri-
cants that meet or exceed military specification MIL-L-
2105D, and API service classification GL-5, are the
minimum requirements for use in Spicer Medium and
Heavy Duty Drive Axles.
The table below indicates which SAE viscosities are
recommended for various temperature ranges the vehicle
will encounter.
AXLE LUBRICANT RECOMMENDATIONS
* Severe service includes any applications operating
at or near maximum GVW or GCW ratings. This
includes normally wet or dusty environment, or
consistent high load and low speed applications.
** Includes Semi-Synthetic blends that meet
MIL-L-2105D specifications.
AMBIENT AIR TEMPERATURE
SERVICE
Recommended lubricant change intervals are dependent
on the application and operating environment. The
following chart should be used to establish proper
change intervals.
SUBMERSION OR DEEP WATER FORDING
In the event the axle assembly should become sub-
merged in water, particularly if over the vent or breather,
it is recommended that the lubricant be drained to
prevent water damage and/or contamination. The axle
assembly should then be refilled with specified lubricant.
AFTER OVERHAUL OR CHANGE INTERVALS
Fill the axle assembly to the bottom of housing fill hole
as shown in the illustration below. It is recommended
that following an overhaul, each side of the axle be
jacked up separately to approximately six inches and
held into position for one minute. This procedure will
allow adequate lubricant to flow into the wheel ends and
help eliminate the possibility of premature damage to
wheel bearings and seals. Lower the vehicle to the floor
and allow ten minutes for lube to return to normal level.
Check and refill assembly to bottom of fill hole to
replace the lubricant that was directed into the wheel
ends.
NOTE: Lubricant close enough to the bottom of the fill hole to be seen or
touched is not sufficient. Lubricant must be level with the fill hole.
