316-6864 Hydraulic Pump — Cat 725 730

This is a high-pressure hydraulic pump, the heart of the machine's hydraulic system, responsible for generating the flow and pressure needed to operate functions like the boom, stick, bucket, and drive motors. Built to meet exacting OEM specifications, it delivers consistent performance and longevity, outperforming worn or failing pumps that exhibit reduced flow or internal leakage. Operators may experience sluggish hydraulic functions, a noticeable loss of power during operation, or whining noises from the hydraulic system if this pump is malfunctioning.

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 symptoms of a failing hydraulic pump include a noticeable decrease in the speed and power of hydraulic functions, such as slow boom or bucket movement. If ignored, the pump's performance will continue to degrade, leading to increased cycle times and potential overheating of the hydraulic fluid. A severely worn pump can cause a complete loss of hydraulic power, rendering the equipment inoperable.

Installation Tip

Thoroughly flush the entire hydraulic system, including lines and components, before installing the new pump to remove any debris. Ensure the pump shaft is properly aligned with the drive coupling to prevent premature wear.

Service Note

Always replace the hydraulic filter and inspect hydraulic fluid for contamination when installing a new hydraulic pump.
