disassembly, reassembly, adjustment and
troubleshooting information) are provided in the ZF Axle
Repair Manuals. (Refer to Section 5.3.8, “ZF Axle Repair
Manuals.”)
Several special axle service tools are required to properly
service the axle assemblies. Contact the local JLG parts
distributor or ZF dealer for ordering information.
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 vehicle safety.
• Some service operations require the use of tools
specifically designed for the purpose. Use the
special tools when and as recommended.
• DO NOT pound, beat or hammer on end yokes
and flanges to remove or to install them. Damage
to axle components can occur. Remove and install
end yokes and flanges by following the recom-
mended procedures in the appropriate ZF axle
service manual.
• DO NOT attempt carrier and differential removal
and installation, and differential and pinion disas-
sembly and assembly, without thoroughly under-
standing the instructions in the appropriate ZF
publications.
