Spicer Drive Axles Service Manual - Manual (Page 5)

* Severe service includes any applications operating at
or near maximum GVW or GCW ratings. This
includes normally wet or dusty environments, or
consistent heavy load and low speed applications.
** Includes Semi-Synthetic blends that meet
MIL-L-2105D specifications.
AXLE LUBRICANT RECOMMENDATIONS
To ensure proper lubrication and operating temperature,
correct lubricants and lubricant levels must be obtained.
RECOMMENDED LUBRICANTS
Mineral or Synthetic based hypoid gear lubricants that
meet or exceed military specification MIL-L-2105D, and
API service classification GL-5, are the minimum require-
ments 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.
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
submerged in water, particularly if over the vent or
breather, it is recommended that the lubricant be
drained and all parts be inspected for water damage
and/or contamination. Reassemble the carrier to the
housing and refill with specifed gear 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 seperately 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.
