(A) Centerline between pins.
Note: Make sure that the bores in the stick are clean prior to the installation of the bearings and the lip seals.Note: Bore surfaces must be free of paint and grease prior to installation of bearings. After installation of the bearings, apply Tooling (J) to the bores and the bearings.Note: The sleeve bearings at the pin joint for the stick and the boom must be assembled so that the thrust groove is directed open to the center cavity.
Install the two bearings in the stick at the pin joint for the stick and the boom. Lower the temperature of the bearings. Position the thrust groove (Y) so that angle (P) is 60 5 degrees. This is shown in Illustration 1. Use Tooling (F) to install the bearings in the pin bore until each one is 9.5 .8 mm (0.37 0.03 inch) below the outside surface of the stick.

(A) Centerline between pins.
Install the two bearings in the stick at the pin joint for the attachment. Lower the temperature of the bearings. Position the thrust groove (X) so that angle (R) is 60 5 degrees. This is shown in Illustration 2. Use Tooling (F) to install the bearings in the pin bore until each one is 9.5 .8 mm (0.37 0.03 inch) below the outside surface of stick. Note: In order to prevent dirt and debris from entering the pin bores of the stick, install the lip seals so that the sealing lip is facing toward the outside of the pin bores.
Use Tooling (F) to install the two lip seals in the stick at the pin joint for the stick and the boom. Install the seals so that the sealing lip is facing toward the outside of the pin bores. Install the seals until each one makes contact with the bearing.
Use Tooling (F) to install the two lip seals in the stick at the pin joint for the attachment. Install the seals so that the sealing lip is facing toward the outside of the pin bore. Install the seals until each one makes contact with the bearing.
Applygrease (J) on the bearings and seals in the stick.

Typical Example
Note: Make sure that the pin bores in the stick and the boom are clean and free of dirt prior to the installation of the stick.
Fasten an appropriate lifting device and a hoist to lifting eye (2) on stick (3).
Raise the stick and put the pin bores of the stick and the boom in alignment with each other. You may need to move the stick and the boom in order to align the pin bores.
Make sure that the threaded puller hole in pin assembly (8) is clean. Install Tooling (G) in the end of the pin assembly.
Apply Tooling (J) on pin assembly (8).
If the pin assembly is equipped with a spacer, install the spacer on the pin assembly.
Use two persons in order to temporarily position pin assembly (8) at the pin joint. Use
