Attach a suitable lifting device to the stick. Position the stick on the boom. Slide the stick to one side until the stick makes contact with the boom. Measure the total clearance between the stick and the boom at the pin bore. The total clearance must not be more than 0.8 mm (0.03 inch). If the total clearance is less than 0.8 mm (0.03 inch), the addition of shims between the stick and the boom will not be required. Apply 5P-0960 Molybdenum Grease on pin (6) and install the pin.

If the total clearance is more than 0.8 mm (0.03 inch), the addition of shims will be required. Install the shims between the stick and the boom on the side opposite retaining bolt (4). Apply 5P-0960 Molybdenum Grease on pin (6) and install the pin. Install washer (5) and retaining bolt (4). Tighten the retaining bolt to a torque of 100 ± 20 N·m (75 ± 15 lb ft).
Be sure that the stick is touching the ground. Determine the correct amount of shims that are used between the rod end of the stick cylinder and the stick. Refer to Disassembly and Assembly, "Stick Cylinder - Install" for the proper procedure.

Check the condition of the O-ring seals in the ends of hose assemblies (1). If any of the seals are damaged, use new parts for replacement. Connect hose assemblies (1).
Fill the hydraulic oil tank with oil. Refer to Operation and Maintenance Manual, SEBU7421, "Hydraulic Oil Level - Check" for the proper procedure. Lubricate the stick and stick cylinder mounting pins. Refer to Operation and Maintenance Manual, SEBU7421, "Boom and Stick Linkage - Lubricate" for the proper procedure.
Remove Tooling (A) from the boom.
Start the engine, and run the engine at low idle speed. Extend the bucket cylinder to the halfway position. Retract the cylinder rod. The cylinder should be cycled in this manner for approximately ten cycles in order to remove the air from the hydraulic system. Recheck the oil level in the hydraulic oil tank.
