This Hydraulic Pump is the heart of the excavator's hydraulic system, generating the flow and pressure needed to operate functions like the boom, stick, bucket, and travel motors. It is engineered to meet demanding OEM performance requirements, providing consistent power output, unlike a worn pump that may suffer from reduced flow or internal leakage. Operators may notice slow or sluggish hydraulic functions, a lack of power during operation, or unusual noises from the hydraulic system when this pump is failing.

Flush hydraulic lines before fitting new components. Use only manufacturer-specified hydraulic fluid. Check O-rings and backup rings for correct orientation. Bleed air from system after installation.
Always consult the OEM service manual for model-specific torque values and procedures. WhatsApp our technical team if you need fitment guidance.
The first indication of a failing hydraulic pump is often a noticeable decrease in the speed and power of hydraulic functions, such as the boom or bucket. If ignored, the pump's performance will continue to degrade, leading to intermittent operation, increased cycle times, and potential overheating of the hydraulic fluid. Continued operation with a severely worn pump can result in the inability to perform essential tasks, leading to significant downtime and potential damage to other hydraulic components.
Before installing the new pump, ensure the hydraulic reservoir is clean and the fluid is free of contaminants. Prime the new pump with clean hydraulic fluid before connecting the lines to prevent dry running.
When replacing the hydraulic pump, it is crucial to inspect and clean or replace the hydraulic filter and check the hydraulic fluid for signs of contamination.
