2. Release the pressure in the hydraulic system as follows: a. Shut off the engine, and put the hydraulic activation control lever in the "Lock" position.b. Move the control levers for the boom, bucket, stick and swing through their full travel strokes. This will relieve any pressure that may be present in the pilot system.c. Slowly loosen the Fill/Vent plug on the hydraulic oil tank to release the pressure.d. Tighten the Fill/Vent plug on the hydraulic oil tank.e. The pressure in the hydraulic system has now been released. Lines and components can now be removed. 3. Fasten a hoist to the rod end of the bucket cylinder as shown. Put a wood block (3) under the link assemblies as a support.4. Remove the two nuts and retaining bolt (1). Remove pin (2). The weight of the pin is 23 kg (50 lb). 5. Raise bucket cylinder (4) until it is level; then fasten a lifting strap and a hoist to the head end of the bucket cylinder as shown. Disconnect two hoses (5) from the bucket cylinder. Put plugs in the ends of the hoses to keep dirt and debris out of the hydraulic system. 6. Remove pin assembly retaining bolt (6), the washer, pin assembly (7) and the spacer. Remove the bucket cylinder. The weight of the bucket cylinder is 147 kg (325 lb). Machines may be equipped with shims between the stick and bucket cylinder at the stick-to-bucket cylinder pin joint. For assembly purposes, put identification marks on the shims as to their location.7. Remove the shims (if so equipped) at the stick-to-bucket cylinder pin joint. The following steps are for the installation of the bucket cylinder.8. Be sure the pin bores in the stick, link assemblies, and bucket cylinder are clean and free of dirt prior to installation of the bucket cylinder.9. Fasten a hoist to bucket cylinder (4), and put it in position in the stick. Be sure the pin bores in the stick and bucket cylinder are in alignment. Also, be sure the grease fitting in the head end and rod end of the bucket cylinder are facing away from the stick.10. Apply 5P-0960 Multipurpose Grease on pin assembly (7). Temporarily install the pin assembly. Do not remove the hoist from the bucket cylinder at this time.

Measure the total clearance between the bucket cylinder and stick at the pin bore. The total clearance of (a) and (b) must not be more than 1.6 mm (0.06 in). If the total clearance is less than 1.6 mm (0.06 in), the addition of shims between the bucket cylinder and stick will not be required. If the total clearance is more than 1.6 mm (0.06 in), add the correct thickness of shims to obtain the necessary clearance.12. If it has been determined that shims need to be installed between the stick and bucket cylinder, remove pin
