Axles, Drive Shafts, Wheels and Tires
5.2 GENERAL INFORMATION
Before performing any inspection, maintenance or
service operation, thoroughly clean the unit. The axles
and drive shafts should be checked and repaired only by
experienced service technicians who are aware of all
safety instructions and particular component features.
Use suitable products to thoroughly clean all
disassembled mechanical parts to help prevent personal
injury to the worker and prevent damage to the parts.
Carefully inspect the integrity of all moving parts
(bearings, yokes, tubes, gears, shafts, etc.) and fasteners
(nuts, bolts, washers, etc.) as they are subject to major
stress and wear. Always replace elastic locknuts and any
damaged, worn, cracked, seized or otherwise improper
parts that could affect the safe and proper functioning of
the machine, axles and drive shafts.
5.3 AXLE ASSEMBLIES
5.3.1 Axle Serial Number Plate
The axle serial number plate is located on the inside of
the right yoke. Information on the serial number plate is
required in correspondence regarding the axle.
Supply information from the axle serial number plate
when communicating about an axle assembly or axle
components.
5.3.2 Axle Specifications
General axle specifications are found in Section 2,
“General Information and Specifications.” Axle
(differential housing) fluid information is found in Section
2.4, “Fluids, Lubricants and Capacities.”
5.3.3 Axle Internal Service
Detailed axle service instructions (covering the axle,
differential, brakes and wheel-end safety, repair,
disassembly, reassembly, adjustment and
troubleshooting information) are provided in the following
manuals.
5.3.4 Axle Maintenance
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 machine 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 machine has been exposed to
water deep enough to cover the hubs, disassemble the
