This is a Bosch Rexroth A10V074 hydraulic pump, a high-performance unit designed for the main hydraulic system of Volvo backhoe loaders. It is built to exacting standards for efficiency and durability, ensuring consistent hydraulic power delivery, unlike a worn pump that may exhibit reduced flow or increased noise. Operators will typically observe a loss of hydraulic power, slow or jerky implement movements, and potentially a whining sound from the pump when it 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.
The initial signs of a failing A10V074 hydraulic pump include a noticeable reduction in the speed and force of hydraulic operations, such as bucket curl or boom lift. If the problem is not addressed, the pump's output will continue to decrease, leading to intermittent operation and potential overheating of the hydraulic fluid. Continued use with a compromised pump can lead to damage to other hydraulic components and system failure.
Before installation, ensure the hydraulic system is thoroughly flushed and the reservoir is clean to prevent contamination of the new pump. Avoid overtightening the mounting bolts, as this can cause stress on the pump housing.
Replace the hydraulic filter, inspect the hydraulic fluid for contamination, and check the suction strainer for blockages.
