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.
Note: Detailed axle service instructions (covering the axle, differential, brakes and
wheel-end safety, repair, disassembly, reassembly, adjustment and
troubleshooting information) are provided in the Zahnradfabrik (ZF) Repair
Manuals.
Note: Several special axle service tools are required to properly service the axle
assemblies. Contact the local JLG parts distributor for ordering information.
CAUTION: Risk of personal injury. Exercise extreme care when using
snap rings or spring-loaded retention devices.
WARNING: Risk of death or serious personal injury if components are
assembled improperly, if components are assembled
improperly, if incompatible, worn or damaged components are
used, or if components are used in a non-approved
application. Obtain proper training, follow recommended
procedures, and use proper tools and safety equipment. Wear
safety glasses at all times when working on the machine and
machine components.
WARNING: An improperly supported machine can fall, causing death or
serious injury. When removing the axle assembly from the
machine, properly support the machine. If servicing axle
components with the axle attached to the machine, securely
support the carrier, differential, pinion assemblies and wheel
ends.
Important:When replacing a fastener, replace it with one of equal or
higher grade and quality. Torque fasteners to the specified
value for the application.
Important:The use of replacement parts provided by other than the original
manufacturer is not recommended, as such use may cause axle
failure and affect machine safety.
• Some service operations require the use of tools specifically designed
for the purpose. Use the special tools when and as recommended.
