1076 x 538.52 mm (42.4 x 21.2 in)    
31 kg (68 lb)    The dimensions shown in the Tool Specifications table are for the vertical length and the horizontal width. The outer-most tubing near the center of the contracted tool (two small spacers that host the bolt and nut for the outer vertical tubing) has a diameter of 69.85 mm (2.75 in).Note: For more information on setting the extension arms length, refer to the specific Disassembly and Assembly service manual for the component to be lifted.Operation Section
Operation
Note: The adjustable C-frame assembly weighs 31 kg (68 lb).
Due to the shape and weight of the tool, use a suitable lifting device or get help when lifting the C-frame assembly.
Illustration 6 g03321612
Identify the load and weight of the machine component to be lifted. Do not exceed the Working Load Limit (WLL).
Make sure that the lifting eyebolt is fully inserted. Tighten to standard torque.
After achieving desired length, make sure that bolts are fully inserted and tightened with nuts to standard torque.
Illustration 7 g03322081
Identify and measure the desired vertical length of the tooling required for the operation and adjust the inner vertical tube at the desired settings before loading the tool onto a suitable hoist or lifting device.Note: The Working Load Limit (WLL) of the tooling changes as the vertical length of the tooling changes.Note: The bolts and nuts used to keep the vertical tubes at the desired lengths should be tightened to standard torque before proceeding to the next step.Note: This step requires the tool to be laying flat on the surface or ground.
Illustration 8 g03322137
Attach a suitable hoist or lifting device to the upper eyebolt assembly (2) .Note: The Working Load Limit (WLL) of the hoist or lifting device used for this step should be more than the weight of the machine component being lifted and the tooling used to lift it.
Refer to the appropriate Disassembly and Assembly service manual for the machine component to be lifted.
Illustration 9 g03322200
Turn the hex nuts (5) with a 22.22 mm (7/8 in) hand wrench until the desired horizontal location is achieved.Note: The Working Load Limit (WLL) of the tooling changes as the horizontal length of the tooling changes.Note: Avoid getting trapped between tooling and the machine component. Stay a safe distance away from the tooling and the machine component during the installation and removal of the machine component.Note: Operate the wrench by hand only, and when the tool is in a stable condition.Inspection and Maintenance Section
Inspection
Illustration 10 g03322272
Inspect all welds and check for damaged, cracked, or bent components. Inspect tooling prior to each use. If damage is found, destroy the tool and dispose of as scrap. Replace damaged tool with new product.
Do not use unless the Working Load Limit (WLL) identification markings
