This is a Gear Pump, a vital component of the hydraulic system in Volvo excavators, responsible for generating consistent hydraulic flow for various functions. Manufactured to meet strict OEM quality and performance standards, it ensures reliable operation and durability compared to a worn or failing unit. Operators may notice a decrease in the speed of hydraulic functions, such as boom or bucket movement, or hear whining noises from the hydraulic pump when this unit begins to fail.

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.
A failing gear pump might initially cause a slight reduction in the speed of hydraulic operations or a noticeable increase in hydraulic system noise. If ignored, the pump's output will continue to decrease, leading to sluggish or unresponsive hydraulic functions and potential overheating of the hydraulic fluid. Continued operation with a faulty pump risks damage to other hydraulic components due to insufficient flow or pressure.
Ensure the hydraulic system is clean and filled with the correct type and level of hydraulic fluid before installing the new pump. Avoid overtightening the mounting bolts, as this can distort the pump housing and lead to leaks.
Inspect the hydraulic filter and fluid for signs of wear particles, and check all hydraulic lines and fittings for leaks or damage.
