367-8077 Hydraulic Piston Pump — Cat 950Gc 950H

This hydraulic piston pump is the heart of the machine's hydraulic system, generating the flow and pressure needed to operate various functions like lifting, steering, and implement movement. Built with precision-engineered components and high-grade seals, it ensures consistent performance and longevity, unlike a worn pump that suffers from internal leakage and reduced efficiency. Operators may notice slow or erratic hydraulic functions, a whining noise from the pump area, or a complete loss of hydraulic power.

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 hydraulic pump is often a noticeable decrease in the speed or power of hydraulic functions. If ignored, this can lead to intermittent operation, increased system temperature, and eventual loss of all hydraulic power. Continued operation risks damage to other hydraulic components due to lack of lubrication and pressure.

Installation Tip

Thoroughly flush the hydraulic system and replace the hydraulic filter before installing the new pump to prevent contamination. Ensure the pump shaft is properly aligned with the drive coupling to avoid premature wear.

Service Note

Always flush the hydraulic system and replace the hydraulic filter when installing a new hydraulic pump.
