1. 1

   Inspect the wiring harness, pins, and connectors going to External Hydraulic Valve 4 for corrosion, damage, or loose connections

2. 2

   Perform a mechanical leak-down test by placing a ball valve in line ahead of the spool valve. If the implement holds with the ball valve closed, the spool valve is internally bypassing

3. 3

   Check the valve for external hydraulic leaks or sticking when actuated in either direction

1. 1

   Disconnect Power

   Turn off the tractor and disconnect the battery to ensure safety while working on the electrical connections.

2. 2

   Relieve Hydraulic Pressure

   Ensure all hydraulic pressure is relieved from the system before loosening any lines.

3. 3

   Address Wiring

   Repair or replace any damaged wiring or connectors leading to Valve 4.

4. 4

   Valve Repair/Replacement

   If the valve is sticking or leaking, remove the spool valve assembly. You can either rebuild the valve using an OEM spool valve repair kit or replace the entire spool valve assembly.

5. 5

   Reinstallation

   Install the new or rebuilt valve, reconnect the hydraulic lines, and plug in the electrical harness.

6. 6

   Clear Codes

   Use a compatible Massey Ferguson diagnostic tool or interface device to clear the 0A.41.24 DTC from the system and test the hydraulic remote for proper operation.
