Maintenance & Inspection
Damaged Hub
(Broken flange, stud replacement, stripped hub cap bolt hole,
etc.) If the hub is damaged and needs to be replaced, replace-
ment of entire Spicer branded hub unit assembly is required
for warranty continuance.
Seal Replacement
If service is required on the seal or if the oil is contaminated,
the hub unit must be disassembled and serviced. Seal
replacement is required in all cases when the hub is removed
from the axle.
Wheel End Inspection - Oil Bath
Simple Inspection (Pre-Trip/In-Service)
Walk around vehicle and check wheel-ends for obvious signs
of lubricant leakage, such as hubcap gasket and wheel seal
areas, oil soaked brake linings. Check for broken or missing
components. Any seepage is reason for further inspection and
appropriate action.
Take appropriate action if leaks or oil soaked brake linings are
noted.
Note For Drivers:
After making an enroute stop, walk around the unit and feel
the hubs. If there is any significant differences in tempera-
tures or excessive temperature, contact your maintenance
department. When feeling hubs for temperature, seasonal
influences should be taken into consideration.
If wheel-ends are equipped with a sight glass on the hubcaps,
check to ensure the oil is at the proper fill level.
Note: Oil residue may be present at the vent area. This is an
indicator that the system is venting properly. This
should not be construed as system leakage.
100,000 Miles or Annual Inspection
For non-driven axles check lubricant level and condition. If
lubricant is contaminated replace old lubricant with the same
type lubricant. If lubricant condition is good and level is low,
fill to the proper level. Check for any signs of leakage at the
seal or hubcap gasket areas. Check for oil soaked brake lin-
ings.
For driven axles, check for any signs of leakage at the seal or
axle flange gasket areas. Also check for leaks at hub fill hole if
so equipped. Check for oil soaked brake linings.
Take appropriate action if leaks or oil soaked brake linings are
noted.
Wheel End Inspection - Grease Pack
Simple Inspection (Pre-Trip/In-Service)
Walk around vehicle and check wheel-ends for obvious signs
of lubricant leakage, such as hubcap gasket and wheel seal
areas, grease soaked brake linings. Check for broken or miss-
ing components. Any seepage is reason for further inspection
and appropriate action.
Note For Drivers:
After making an enroute stop, walk around the unit and feel
the hubs. If there is any significant differences in tempera-
tures or excessive temperature, contact your maintenance
department. When feeling hubs for temperature, seasonal
influences should be taken into consideration.
