1055080 12-Tooth / 150- Psi — Cat 3408

This component is a pressure relief valve, designed to protect hydraulic systems from over-pressurization by venting excess fluid. It is crucial for maintaining system stability and preventing damage to pumps, hoses, and actuators. A malfunctioning relief valve may cause inconsistent system pressure, sluggish operation, or audible relief valve chatter.

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

Inconsistent hydraulic system pressure or sluggish operation of hydraulic functions are the first signs of a faulty pressure relief valve. If the valve sticks open, the system may not build adequate pressure, leading to a loss of power and control. If it fails to open, the system can experience dangerously high pressures, risking damage to hoses, seals, and other components.

Installation Tip

Ensure the valve seat in the manifold or housing is clean and free of debris before installing the new valve. Do not reuse old sealing washers or O-rings.

Service Note

Inspect the hydraulic fluid for contamination and consider flushing the system if the relief valve failed due to debris.
