This is a main hydraulic pump that supplies pressurized fluid to the excavator's primary hydraulic functions, such as boom, stick, and bucket actuation. It is engineered to meet stringent OEM performance standards, ensuring consistent flow and pressure compared to a worn pump that may exhibit reduced output. Operators may notice sluggish or unresponsive hydraulic movements, or a loss of lifting and digging power when this pump begins to fail.
Always verify with serial number before ordering.

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.
Initial signs of failure may include a slight decrease in hydraulic system responsiveness or a faint whining noise from the pump. If ignored, the pump's output will continue to diminish, leading to slower cycle times and reduced breakout force. Continued operation with a failing pump risks overheating the hydraulic oil and damaging other system components.
Ensure the hydraulic system is properly flushed before installation to remove any debris that could damage the new pump. Avoid overtightening the mounting bolts, as this can distort the pump housing.
Inspect the hydraulic oil and filter for contamination and replace the hydraulic filter as part of the pump replacement procedure.
