Occasional Maintenance
General Info
The maintenance and service intervals for the following components will depend very much on the operating conditions,
and therefore it is almost impossible to specify the intervals beforehand.
The operator must select appropriate intervals for the occasional maintenance.
If in doubt, contact your local HARDI dealer.
Lifting and Removing the Pump
When lifting and removing the pump, use a shackle fitted to the built-in
lifting eye located between the heads (A).
±
WARNING! To prevent damage in case of a free-falling pump, use
lifting gear and a steel shackle with at least 3.5 tonnes max. tensile
strength.
÷
NOTE! Pump weight is approximately 75 kg.
Speed Transducer for the Pump
The speed transducer that measures rotations per minute (RPM), is
located at the inner side of the PTO shield.
The sensor is an inductive type, which requires metallic protrusions to
pass by it to trigger a signal.
If exchanging the sensor, it must installed accurately to function
properly.
Adjustment
1. Adjust the air gap (A) between sensor tip and the protruding
pump part by turning the counter nuts at the support bracket for
the sensor.
The air gap (A) must be set to 1 mm (+0.3/-0.0 mm).
Use a feeler gauge or similar tool to verify.
2. Verify transducer function on the controller:
• SmartCom:
Monitor the menu [4.3.5.1.3 Pump RPM].
