Circuit Relief and Check Valve Hose Connections: Removal Procedure

This section provides a detailed guide on removing the hose connections for circuit relief and check valves. Follow these steps to ensure safe and efficient maintenance:

Steps for Removal

1. Park the machine securely on a level surface.
2. Raise the loader bucket for easy access.
3. Position the loader strut securely in place.
4. Engage the parking brake and stop the engine.
5. Carefully remove the left and right side panels from the engine compartment.
6. If available, use a vacuum pump to connect to the hydraulic reservoir, preventing hydraulic fluid loss. If not:
   • Gradually loosen the hydraulic reservoir fill cap to release air pressure.
   • Remove the fill cap completely.
   • Place a clean container under the hydraulic reservoir’s drain plug (the reservoir holds approx. 19 U.S. gallons or 72 liters).
   • Remove the drain plug and allow the hydraulic fluid to drain completely.
7. Disconnect hoses from both the check valves and the circuit relief valve, ensuring they are labeled with identification tags.
8. Securely install caps and plugs on the hoses and fittings to prevent system contamination.
9. Unscrew and remove the nuts, lock washers, washers, and bolts that attach the circuit relief valve to its mounting bracket.
10. Carefully detach the check valves and circuit relief valve from the equipment.
