GASKET KIT 1441144 - Caterpillar

1. Release the pressure in the hydraulic system as follows:
At operating temperature, the hydraulic oil is hot and under pressure. Hot oil can cause burns. Sudden movement of the machine or release of oil pressure can cause injury to persons on or near the machine. To prevent possible injury, perform the following procedure before working on the hydraulic and steering systems.
a. Move the machine to a smooth horizontal location. Move away from working machines and personnel. Lower all implements to the ground. Install the wheel lean pin in front axle.b. Permit only one operator on the machine. Keep all other personnel either away from the machine or in view of the operator.c. Activate the parking brake. Place all implements on the ground and put the blade in the "FLOAT" position.d. Stop the engine.e. Turn the steering wheel back and forth several times to relieve pressure in the steering accumulator.f. Carefully loosen the filler cap on the hydraulic tank to release pressure in the tank.g. Be sure all hydraulic pressure is released before any fitting, hose, or component is loosened, tightened, removed or adjusted.h. Tighten the cap on the hydraulic tank.i. The pressure in the hydraulic system must be released before lines or components can be removed.
Hydraulic pressure can exist in the hydraulic lines between the control valves and the cylinders with the engine stopped. Manually relieve pressure before working on any hydraulic circuit.
2. Place Tooling (A) under the draw bar boss, in order to raise the wheels off of the floor. Refer to the instructions in "Remove and Install Front Tires and Rims." Remove the front tires and rims. Attach lifting slings and a hoist to the front axle. 3. Put identification marks on hose assemblies (1), (2), (3), (4), (5) and (6) for installation purposes. Disconnect hose assemblies (1) and (2) from the wheel lean cylinder.4. Disconnect hose assemblies (3), (4), (5) and (6) from the steering cylinders. Plug the fittings on the hose assemblies in order to prevent the loss of oil, and to keep dirt out of the hydraulic system. Later machines will have an axle pin with a retention plate on the end of the pin. A bolt will hold this retention plate to the frame.5. Remove bolt (7), the nut and washer that hold pin (8) to the machine frame. 6. Remove pin (8) from the front axle and the machine frame. 7. Remove washers (11) from between the front of the axle and the machine frame. Remove the washer from between the rear of the axle and the machine frame. Put identification marks on the washers for installation purposes. Carefully lower the axle away from the machine. The weight of the axle is 976 Kg (2150 lb). 8. Remove lip seal (10) from the front of the axle. Use Tooling (B) in order to remove bearing (9) from the front of the axle. 9. Remove lip seal (12) from the rear of the axle. Use Tooling (B) in order to remove bearing
