Spicer Drive Axles Service Manual G & M - Manual (Page 5)

APPLICATION
To ensure proper lubrication and operating temperature,
correct lubricants and lubricant levels must be obtained.
RECOMMENDED GEAR 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.
AMBIENT AIR TEMPERATURE
AXLE LUBRICANT RECOMMENDATIONS
SUBMERSION OR DEEP WATER FORDING
In the event the carrier housing should become
submerged in water, particularly if over the vent plug, it
is recommended that the lubricant be drained and all
internal parts be inspected for water damage and/or
contamination. Reassemble the carrier to the housing
and refill with specified 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.
PATENTED, PRESSURIZED LUBRICATION SYSTEM
The lube system for our two-speed axle line is unique in
the industry. It's closed and pressurized so that oil
constantly flows to critical components. The tapered
roller bearings act as a pump which provides pressurized
lube through the internal channels in the carrier to the
differential bearings, planetary gears, and differential
gears.
SERVICE
Recommended lubricant change intervals are dependent
on the application and operating environment. The
following chart should be used to establish proper
change intervals.
