320-3065 Heavy Duty Pressure Switch — Cat C15 C18

This is a heavy-duty pressure switch, designed to monitor and signal changes in hydraulic system pressure. It is built to meet rigorous OEM quality standards, offering reliable and accurate pressure sensing compared to a worn switch that may stick or provide false readings. Operators might notice inconsistent hydraulic system operation, such as sluggish implement movement, loss of hydraulic power, or warning lights related to hydraulic pressure.

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

The initial symptom of a failing pressure switch is often erratic or inconsistent operation of the hydraulic system, such as intermittent loss of power or sluggish movement of implements. If ignored, the switch may fail to signal critical pressure drops or over-pressurization, leading to component damage. Continued operation with an unreliable pressure switch can result in damage to hydraulic pumps, valves, or cylinders due to improper pressure regulation.

Installation Tip

Ensure the hydraulic system is properly depressurized before removing the old switch to prevent injury and fluid loss. Apply a small amount of thread sealant suitable for hydraulic systems to the threads of the new switch before installation.

Service Note

Inspect the hydraulic fluid for contamination or degradation, and check the hydraulic filter for signs of blockage or damage.
