1. Raise the lift arms and engage the lift arm brace. Refer to the Operation and Maintenance Manual, "Loader Lift Arm Brace Operation".
2. Release the hydraulic system pressure. Refer to the Disassembly and Assembly Manual, "Hydraulic System Pressure ? Release".
3. Raise the cab. Refer to Disassembly and Assembly Manual, "Cab ? Tilt".
4. Place an oil-absorbent pad under the implement and self-level valves.
5. Loosen the self-level fittings in the following sequence. Loosen the couplings enough to allow the self-level valve to move slightly, but do not completely remove the couplings at this time.
5.1 - Coupling on 258-2883 tube to Implement Valve (1-1/8")
5.2 - Rear bottom self-level tube assembly coupling (1-1/8")
5.3 - Front bottom coupling (13/16")
5.4 - Front top coupling (13/16")
5.5 - Jam nut on fitting for 258-2883 tube to Implement Valve (1-1/16")
5.6 - Two (2) bolts holding the Self-Level Valve in place (10 mm)

6. Loosen the implement valve-end coupling of the 258-2883 Tube (1-1/18") and remove the tube from the machine. Loosen the implement valve fitting (1-1/4") and remove from the machine.

7. Loosen the four (4) bolts on the right side removable access panel (13 mm); move the panel to the side for clearance to spin the self-Level valve elbow fitting. Remove the top fitting on the self-level valve from the machine.

8. Install the new 6V-8629 Elbow-Face Seal fitting and corresponding seals (2M-9780 Seal-O-Ring and 6V-9746 Seal-O-Ring) in the top port of the self-level valve. Do NOT torque the jam nut fitting at this time to ease elbow orientation during replacement tube assembly in step 10.

9. Install the new 6V-8637 Connector-Seal fitting and corresponding seals (3D-2824 Seal-O-Ring and 6V-9746 Seal-O-Ring) to the open port on the implement valve. Tighten the fitting
