369-6595 Piston Pump — Cat C15

This piston pump is a high-pressure component within the hydraulic system, responsible for converting mechanical energy into hydraulic flow. It is engineered to precise tolerances, offering superior durability and consistent performance over a worn or damaged pump. Operators may notice a loss of hydraulic power, sluggish implement movement, or unusual noises from the hydraulic system when this pump begins to fail.

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

Initial symptoms of a failing piston pump include a noticeable reduction in hydraulic system pressure and slower response times for implements. If ignored, the pump's output will continue to degrade, leading to a significant loss of operational capability. Continued use risks damage to other hydraulic components due to inadequate flow or pressure.

Installation Tip

Thoroughly clean the hydraulic system and flush all lines before installing the new pump to prevent contamination. Never run the pump dry; ensure it is properly primed with hydraulic fluid before initial startup.

Service Note

Replace the hydraulic filter element and inspect hydraulic fluid for contamination when servicing the piston pump.
