Lubrication
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 particles.
CAUTION:
EXERCISE CARE
SAFE AREA. WEAR SAFETY
TO DIRECT COMPRESSED AIR INTO
GLASSES.
Filling
Remove the filler hole plug from
the center of the axle housing
cover and fill the axle with
approved lubricant until level
with the bottom of the hole.
Forward axles:
Add two pints
(0.94 liters) of lubricant through
filler hole at the top of the differ-
ential carrier near the power
divider cover.
NOTE:
Lube fill capacities in the
adjacent chart are good guidelines
but will vary somewhat on the
basis of the angle the axle is
installed in a particular chassis.
Always use the filler hole as the
final reference. If lube is level with
the bottom of the hole, the axle is
properly filled.
Axle Installation Angles
Axles installed at angles exceeding
10 degrees or operated regularly
in areas of continuous and lengthy
grades may require standpipes to
allow proper fill levels.
For specific recommendations,
contact your local Spicer repre-
sentative.
