Massey Ferguson 0A.20.11 – Mid Mount Valve Module: External Hydraulic Valve 2 Issue

Indicates a malfunction within the second external hydraulic remote/spool valve circuit. This can be caused by a connection problem on the hydraulic valve, an issue with the spool position sensor value, or a communication failure between the dash and the valve module.

1. 1

   Inspect Electrical Connections: Check the wiring harness and connectors at External Hydraulic Valve 2 for corrosion, backed-out pins, or physical damage.

2. 2

   Test the Spool Position Sensor: Verify the sensor is reading correctly and sending the proper voltage/signal back to the control module.

3. 3

   Check CAN Communication: Ensure there is proper communication between the Dash and the Valve Module.

4. 4

   Mechanical Inspection: Check the valve body for debris or sticking spools that could prevent the valve from actuating properly.

1. 1

   Depressurize the System

   Turn off the tractor and relieve all hydraulic pressure from the system before beginning work.

2. 2

   Disconnect Electronics

   Unplug the electrical harness from the External Hydraulic Valve 2 solenoid and spool position sensor.

3. 3

   Remove the Valve

   Unscrew the retaining plugs/bolts. Carefully extract the valve body (spool slice), recovering any shims, springs, and O-rings.

4. 4

   Inspect and Replace

   If the valve is mechanically bound or the internal sensor has failed, replace the Electric Spool Slice.

5. 5

   Reassembly

   Fit the new valve body into the hydraulic block using new O-rings. Tighten the retaining plugs to the OEM specified torque (e.g., 50-60 Nm depending on the specific block).

6. 6

   Refill and Test

   Top up the transmission/hydraulic oil level.

7. 7

   Programming

   Crucial step — New electric spool slices must be programmed/calibrated to the tractor using a compatible Massey Ferguson diagnostic tool.

8. 8

   Clear Codes

   Clear the 0A.20.11 DTC and test the hydraulic circuit for proper operation and leaks.
