This is a K3V140Dt main hydraulic pump, engineered to deliver high-volume, high-pressure hydraulic fluid essential for the operation of Volvo excavators. It powers the primary functions such as the boom, arm, bucket actuation, and travel motors. A worn or failing pump will cause a noticeable reduction in hydraulic system performance, leading to slow or weak machine movements and potential overheating.

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 initial indication of a failing main hydraulic pump is a significant loss of power and speed across all hydraulic functions, making the excavator feel sluggish. Continued operation can lead to overheating of the hydraulic oil and potential internal pump damage, characterized by whining or grinding noises. The worst-case scenario is a complete loss of hydraulic pressure, halting all machine operations.
Before installation, ensure the hydraulic reservoir is thoroughly cleaned and that all hydraulic lines are free of debris. It is crucial to prime the new pump with clean hydraulic fluid before initial startup to prevent dry running and damage.
Always replace the hydraulic filter and inspect the hydraulic fluid for any signs of contamination or metal particles when servicing the main hydraulic pump.
