BCU 523749.31 (BCU )

Code: 523749.31

Shortcode:

Description:

The information code BCU 523749.31 is displayed to the operator when the rear Power Take-Off (PTO) is not operating in proportion to the engine speed. This situation suggests a potential issue with the PTO control system, where the PTO speed does not adjust according to changes in engine speed, possibly due to mechanical or electronic control issues.

Reaction:

The system advises the operator to switch the rear PTO off and then on again as a preliminary troubleshooting step to potentially reset any electronic glitches and re-establish correct operation.

Recommendations:

  • Reset the Rear PTO: Follow the system’s advice by turning the rear PTO off and then on again. Monitor to see if the issue resolves itself with this simple reset.
  • Inspect PTO Linkage and Connections: Check the mechanical linkages and electronic connections associated with the PTO system. Look for any signs of wear, damage, or loose connections that could affect performance.
  • Test PTO Speed Sensors: Use diagnostic tools to test the sensors that monitor PTO speed. Ensure they are functioning correctly and providing accurate feedback to the control unit.
  • Check Engine-PTO Calibration: Verify that the calibration between the engine speed and PTO speed is correctly set according to manufacturer specifications.
  • Consult a Technician: If resetting and basic checks do not resolve the issue, it may be advisable to consult a qualified technician who can perform a more in-depth diagnosis and potentially recalibrate or repair the PTO system.

Note:

Regular maintenance of the PTO system and adherence to the manufacturer’s service guidelines are essential for ensuring reliable and efficient operation. Early detection and resolution of issues like these help prevent further complications and maintain optimal performance of agricultural machinery. This proactive approach also minimizes downtime and potential losses in productivity.
