CYLINDER GP-BUCKET 3421892 - Caterpillar

At operating temperature, the hydraulic oil tank is hot and under pressure. Hot oil can cause burns. Remove the filler cap on the hydraulic oil tank only when the engine is stopped, and the filler cap is cool enough to touch with your bare hand. Be sure all the hydraulic pressure is released before any fittings, hoses or components are loosened, tightened, removed or adjusted.
d. Carefully loosen the filler cap on the hydraulic oil tank to release the pressure.e. Carefully loosen the plugs at the rear of the tilt cylinder. When the oil from the loosened plugs stops draining, tighten the two plugs. To release the pressure in the attachment cylinders, carefully loosen the two large plugs near the plugs at the top of the loader frame. When the oil from the loosened plugs stops draining, tighten the two large plugs.f. Tighten the filler cap on the hydraulic oil tank.g. The pressure in the hydraulic system has now been released. 4. Remove the bolt, and disconnect clip (1) from the bracket. 5. Remove bolts (2), and disconnect bucket positioner (3) from the tilt cylinder. 6. Loosen the two setscrews, and remove magnet assembly (4) from the pin in the rod end of the tilt cylinder. 7. Remove bolt (6), washer (7) and the spacer from pin (5). 8. Fasten a hoist to the tilt cylinder.9. Put tooling (A) in position on the pin. Fasten a hoist to tooling (A) so it does not fall when the pin is removed. Remove the pin from the rod end of the tilt cylinder. Put plugs in the ends of all hydraulic hoses as they are being disconnected. This will prevent oil loss and keep dirt and debris out of the hydraulic system.10. Remove bolts (8), and disconnect hose assembly (9) from the tilt cylinder. 11. Remove bolts (10), and disconnect bracket (11) from the tilt cylinder. 12. Disconnect grease hose (12) from the pin in the head end of the tilt cylinder. 13. Remove bolts (14) and tube assembly (13) from the tilt cylinder. 14. Remove bolt (16), washer (17) and the spacer from pin (15). 15. Put tooling (B) in position on pin (15). Fasten a hoist to tooling (B) so it does not fall when the pin is removed.16. Remove pin (15) from the head end of the tilt cylinder. 17. Remove tilt cylinder (18) from the machine. The weight of the tilt cylinder is approximately 181 kg (400 lb.).Install Tilt Cylinder
1. Put 50P960 Multipurpose Grease in the pin bores for the tilt cylinder mounting pins. 2. Fasten a hoist to tilt cylinder (18). Put the tilt cylinder in position in the lift arm assembly and the tilt lever.
Do not damage the lip-type seals in the lift arm assembly and the tilt lever when the mounting pins for the tilt cylinder are installed.
3. Install pin (15) that holds the head end of the tilt cylinder to the lift arm assembly.4. Install the spacer, washer (17) and bolt (16) that
