Speed Transducer for Pump

The speed transducer, measuring rounds per minute (rpm), is located at
the inner side of the PTO shield. This sensor is an inductive type, which
requires metallic protrusions to pass by it to trigger a signal.
Adjustment
1. Adjust air gap (A) to 4 mm (+/-0.5 mm). Use a feeler gauge or
similar tool.
2. After adjustment, turn the pump shaft. Verify air gap variations less
than +/-0.5 mm. Check this at the entire circumference.
3. Verify transducer function:
• HC 5500:
Correct fitting is indicated by continuous flashing from
transducer, when the shaft is rotating.
• HC 6500/ISOBUS VT:
Monitor the menu [4.5.4.9.6 PTO pump frequency].
