General Information Section
Introduction
The 128-4775 Lifting Bracket Assembly is a C-style lifting device. The lifting bracket is used to remove and install various final drive components. Additional adapter plates increase versatility and eliminate the need for multiple lifting brackets.
The following features provide maximum versatility:
- The threaded rod adjusts lifting eye to achieve proper center of gravity.
Illustration 3 | g03239616 |
- Lifting capacities are marked at various locations on the top rail of lifting bracket for quick, accurate centering of bracket for each component being lifted.
- Extension assemblies can be attached to the bottom plate allowing bracket to be used on many different components.

Operation Section
Operation
- Identify load to be lifted.
Illustration 6 | g03239576 |
- Attach appropriate lifting device lifting eye (A) on lifting bracket assembly.
- Use a hand wrench to rotate the nut at either end of the threaded rod (B) to adjust the center of gravity for the load to be lifted.
- Attach the load or optional adapter to the mounting plate (D) .
- Use appropriate overhead lifting device to lift and support lifting bracket assembly.
- Only use 10.9 Metric or Grade 8 English hardware to attach load or optional adapter bracket. Tighten all fasteners to the standard torque.

NOTICE |
---|
To avoid damage to the lifting bracket assembly, do not use an impact wrench to rotate the threaded rod. Use a hand wrench or socket. |
Note: Lifting capacity (WLL) markings (C) are stamped on the lifting bracket assembly upper arm. Refer to the appropriate service manual for additional information on setting the lifting eye for the load to be lifted.
NOTICE |
---|
To avoid damage to the lifting bracket assembly, do not adjust the center of gravity with the threaded rod while under load. |
Optional Adapters
Optional adapters can be used to make this tooling more versatile.
Hardware used to assemble adapter plates and bracket assemblies must meet or exceed Grade 8 specifications. Always use hardened flat washers, and tighten all hardware to the correct torque value for the fastener size.
