Maintenance Instructions
•
Inspect, lubricate and adjust the wheel bearings at regular
intervals.
Refer to SECTION 8 — MAINTENANCE
INTERVALS
AND
SPECIFICATIONS
for
the
correct
intervals, lubricants, and torques.
Normal Maintenance
During operation, the air and oil inside the hub/wheel cavity
expands.
It is normal for a mist of oil to be present on the
outside of the hubcap around the vent slit or hole. Over time,
if not wiped off, this film may collect dust and appear unsightly.
If the entire face and end of the hubcap become wet with oil,
investigate the cause. Refer to the Service Manual for repair
procedures.
Routinely clean the hubcap to ensure that the lubricant level
can be easily observed through the clear window as intended.
In situations where the window is clean on the outside but
discolored on the inside, check the lubricant level by removing
the rubber fill/vent plug and insert a finger into the hole.
The specified lubricant level for International® clear window type
hubcaps is from the minimum line to 5/16 inch (.8 cm) above the
minimum line.
If the lubricant level suddenly drops dramatically below the
minimum level, see the Service Manual for diagnostic procedure.
Alignment
Maintaining front axle alignment is very important to achieving
maximum tire life and vehicle control. Inspecting steer axle tires
in the first 3,000 (4828 km) to 10,000 (16,094 km) service miles
will generally show if tires are wearing normally.
•
Rapid outside shoulder wear on both tires indicates too
much toe-in.
•
Rapid inside shoulder wear on both tires indicates too much
toe-out.
•
Excessive wear on the inside or outside of one steer tire
but not the other can indicate a toe-in or toe-out condition
coupled with a misaligned front or rear axle.
•
Pulling to the right or left can indicate misalignment
of the front or rear axle, unequal tire pressures, or a
damaged/mismatched tire.
Refer to the Tires subsection for additional related information.
Rear Axle
Inspection and Lubrication
Check to make sure that the rear axle mounting U-bolts,
attaching or mounting bolts and nuts are securely tightened.
Loose or misaligned rear axles will affect vehicle alignment, tire
wear, and handling. Refer to SECTION 8 — MAINTENANCE
INTERVALS AND SPECIFICATIONS for torque specifications.
Check the rear axle oil level. Proper oil level minimizes gear
wear, heat and damage to the wheel bearings and seals. The
oil level should be at the lower edge of the level inspection hole
when the vehicle is on level ground. Add oil as necessary.
Refer to SECTION 8 — MAINTENANCE INTERVALS AND
SPECIFICATIONS for additional information.
