Installation & Application Notes

Inspect mating surfaces for wear before fitting. Use torque specs from service manual. Replace gaskets and seals as a set — reusing compressed gaskets causes oil leaks. Clean all oil passages with compressed air.

Always consult the OEM service manual for model-specific torque values and procedures. WhatsApp our technical team if you need fitment guidance.

Failure Symptoms

A failing pressure sensor may initially cause intermittent or inaccurate pressure readings displayed on the operator's console. If the issue persists, it can lead to incorrect system adjustments, potentially causing inefficient operation or damage to hydraulic components. Ignoring these symptoms risks compromising the integrity and performance of the entire system.

Installation Tip

Ensure the electrical connector is clean and securely seated to prevent intermittent signal loss. Do not overtighten the sensor into its port, as this can damage the threads or the sensor body.

Service Note

Check the associated wiring harness and connectors for any signs of damage or corrosion when replacing the pressure sensor.
