Remove the boom. Refer to Disassembly and Assembly, "Boom - Remove".
When you are using hydraulic cylinders and puller studs, always ensure that the rated capacity of the puller stud meets or exceeds the rated capacity of the hydraulic cylinder. If the puller stud does not meet or exceed the rated capacity of the hydraulic cylinder, a sudden failure of the puller stud could occur. The sudden failure of the puller stud could result in personal injury or death.
Do not use threaded rods that have not been hardened as tooling with hydraulic cylinders. The maximum rated tonnage should be stamped on one end of the puller studs. Do not use threaded rods that have not been stamped with the rated tonnage.

Make sure that the bores for the sleeve bearings are free of paint and grease prior to the installation of the sleeve bearings. Coat the sleeve bearings and the bearing bores with Tooling (C) prior to the installation of the sleeve bearings in the bores. Sleeve bearings must be installed with the identification numbers toward the outside of the boom.Note: Make sure that the bearings are installed in the bore so that the identification numbers of the bearings are facing outward.

Use Tooling (B) to install lip seal (1) in the pin bore at the foot of the boom. Install the seal with the sealing lip toward the outside of the boom. Install the lip seal until the lip seal makes contact with the sleeve bearing.
Repeat Steps 2 through 3 to install the sleeve bearing and the lip seal on the other side of the boom.
Put a thin coat of Tooling (C) on the sleeve bearings. Put a thin coat of Tooling (C) on the lips of lip seals (1).End By:
Install the boom. Refer to Disassembly and Assembly, "Boom - Install".
