Displacement Limiters Adjustment

Adjust Displacement Limiters

W

Warning

Escaping hydraulic fluid under pressure can have sufficient force to penetrate your skin causing serious
injury and/or infection. Relieve pressure in the system before removing hoses, fittings, gauges, or
components.
Unintended movement of the machine or mechanism may cause injury to the technician or bystanders.
To protect against unintended movement, secure the machine or disable / disconnect the mechanism
while servicing.

C

Caution

Contamination can damage internal components and void the manufacturer’s warranty. Take
precautions to ensure system cleanliness when removing and reinstalling system lines.

1. Install a flow meter in outlet line to measure pump flow.
2. Start the prime mover and allow fluid to reach normal operating temperature.
3. Adjust the control properly to make sure the pump at maximum displacement.
4. Loosen the maximum or minimum displacement limiter lock nut with an external hex wrench and

turn the adjusting screw with an internal hex wrench until the desired flow is achieved.
