5.5 Model 8042, 10042, 10054 Legacy Rev. 10/03
Axles, Drive Shafts, Wheels and Tires
• Before disassembling any parts inside the car-
rier, remove the entire axle assembly from the
vehicle and securely support it with the pinion
facing up in an appropriate stand or rack.
• DO NOT reuse oil or grease seals.
CLEANING: Clean parts with machined or ground
surfaces (such as gears, bearings and shafts) with
emulsion cleaners or petroleum-based cleaners. DO
NOT steam clean internal components and the interior of
the planetary hub and axle housing. Water can cause
corrosion of critical parts. Rust contamination in the
lubricant can cause gear and bearing failure. Remove old
gasket material from all surfaces.
DRYING: Use clean, lintless towels to dry components
after cleaning. DO NOT dry bearings by spinning them
with compressed air; this can damage mating surfaces
due to lack of lubrication. After drying, lightly coat
components with oil or a rust-preventive chemical to help
protect them from corrosion. If storing components for a
prolonged period, wrap them in wax paper.
PERIODIC OPERATION REQUIREMENT: Every two
weeks, drive the vehicle far enough to cause the drive-
train components to make several complete revolutions.
This will help ensure that internal components receive
lubrication to minimize deterioration caused by
environmental factors such as high humidity.
SUBMERSION: If the vehicle has been exposed to water
deep enough to cover the hubs, disassemble the wheel
ends and inspect for water damage and contamination. If
the carrier housing was submerged in water, especially if
the water level was above the vent tube (breather), drain
the axle and inspect internal parts for water damage and
contamination. Before assembling and refilling the unit
with the specified lubricant(s), clean, examine and
replace damaged parts as necessary.
Note: Use a suitable puller for bearing removal. Clean,
inspect and lubricate all bearings just prior to
reassembly. If replacement of a damaged bearing cup or
cone is necessary, replace the cup and cone as a set.
5.3.6 Axle Replacement
a. Outrigger Removal (10042, 10054 Only)
Note: Proceed to Section 5.3.6, c. “Axle Removal” for
Model 8042.
On Models 10042 and 10054 equipped with outriggers, it
is necessary to removal the outrigger assembly before
removing the front axle.
1. Park the vehicle on a firm, level surface, level the
vehicle, ground the attachment, retract the boom,
lower the outriggers; but DO NOT allow the outriggers
to touch the ground; place the travel select lever in the
(N) NEUTRAL position, place the neutral lock lever in
the (N) NEUTRAL LOCK position, engage the parking
brake switch, straighten all wheels and shut the
engine OFF.
2. Place an Accident Prevention Tag on both the
ignition key switch and steering wheel, stating that
the vehicle should not be operated. (Refer to Section
1.5, “Accident Prevention Tags.”)
3. Unlock and open the engine compartment cover. Allow
the engine, transmission and hydraulic fluid to cool.
4. Label and disconnect the wiring harness connectors
at both outrigger cylinder pressure switches (2 and 3).
Remove the wire ties securing the wiring harness to
the outrigger cylinders.
5. Tie a length of string to each pressure switch wiring
connector, and pull the harness out through the
openings (4) at the rear of the outrigger housing.
6. Untie the strings from the wiring connectors and
tape, or otherwise secure the ends of the strings to
the outrigger housing. These strings will be used to
pull the harness through the housing during
installation.
