10. Remove pin assembly retaining bolt (5) and the washer from pin assembly (6).
Typical Example11. Make sure the threaded puller hole in pin assembly (6) is thoroughly clean prior to the installation of Tooling (B). Fasten Tooling (B) to pin assembly (6). Fasten a lifting sling and a hoist to Tooling (B) to support it as shown.12. Using Tooling (B), remove pin assembly (6) far enough until the stick is free of the boom. Do Not remove pin assembly (6) completely out of the boom.13. Remove Tooling (B) from pin assembly (6). Fasten a lifting sling and a hoist to pin assembly (6). Remove pin assembly (6) and the spacer if so equipped. The weight of pin assembly (6) is 41 kg (90 lb). Stick weights can range from approximately 963 to 1324 kg (2123 to 2919 lb).14. Carefully separate the stick from the boom. The combined weight of the stick, the bucket cylinder and the bucket linkage group is approximately 1633 kg (3600 lb). Machines may be equipped with shims between the stick and the boom at the stick-to-boom pin joint. For assembly purposes, put identification marks on the shims as to their location.15. Remove the shims (if so equipped) at the stick-to-boom pin joint. 16. Remove two lip seals (7) from the stick at the stick-to-bucket pin joint. 17. Remove two lip seals (8) from the stick at the stick-to-boom pin joint. For the removal of the lip seals and the bearings from the stick at the stick-to-bucket linkage pin joint, Refer to the topic "Remove & Install Bucket Linkage Group" in this module.18. Remove the two bearings from the stick at the stick-to-boom pin joint and the stick-to-bucket pin joint with Tooling (C). Fasten Tooling (C) to the stick as shown. Fasten a lifting sling and a hoist to Tooling (C) to support it; then remove the bearing. Remove the other bearings in the stick the same way. The following steps are for the installation of the stick.
Make sure the pin bores in the stick are clean prior to the installation of the bearings and the lip seals.
19. Install the two bearings in the stick at the stick-to-boom pin joint. Lower the temperature of the bearings, and install them in the pin bore until each one is 9.5 0.8 mm (.37 .03 in) below the outside surface of the stick. Also, install the bearings so thrust grooves "Y" are positioned at the angle shown in illustration D65823. 20. Install the two bearings in the stick at the stick-to-bucket pin joint. Lower the temperature of the bearings, and install them in the pin bore until each one is 7.5 0.8 mm (.30 .03 in) below the outside surface of stick. Also, install the bearings so thrust grooves "X" are positioned at the angle shown in illustration D65822.
To prevent dirt and debris from entering the pin bores in the stick, install lip seals (7) and (8) with the sealing lip facing toward the
