(1) Position the boom cylinder onto Tooling (C) . (2) Use Tooling (D) to remove the sleeve bearing. Install the sleeve bearing to a depth of 7.5 0.3 mm (0.30 0.01 inch). (3) Use Tooling (E) to remove the sleeve bearing. Install sleeve bearing to a depth of 9.5 0.3 mm (0.37 0.01 inch). (4) Lubricate the seals slightly with the lubricant that is being sealed. (5) Apply Tooling (F) to the wiper seal groove prior to assembly. (6) Lubricate the threads and the face of the locknut with Tooling (G) . Tighten the locknut to a torque of 7900 300 N m (5827 221 lb ft). (7) Lubricate the inner diameters and outer diameters with Tooling (G) . (8) The slit of the ring must turn in the direction of the piston.Installation Procedure

Apply Tooling (H) onto pin assembly (13) . Install pin assembly (13) and bolt (12) .
Illustration 11 g01320072
Slide boom cylinder (6) to one side until boom cylinder (6) contacts the frame. Measure the total clearance between boom cylinder (6) and the frame at the pin bore. The total clearance of Dimension (a) and Dimension (b) cannot be more than 1.0 mm (0.04 inch). If the total clearance is less than 1.0 mm (0.04 inch), the addition of shims between the boom cylinder and frame will not be required. If the total clearance is more than 1.0 mm (0.04 inch), add the correct thickness of shims in order to obtain the necessary clearance.
