Rexroth AHA10VO variable hydraulic pump for Preciculture HP9006 equipment

If you run or maintain a Preciculture self-propelled sprayer or straddle-tractor chassis, you've probably already heard the code "HP9006" from a parts counter or a cross-reference catalog. It isn't a marketing name — it's the application reference that ties a specific Bosch Rexroth AHA10VO variable displacement piston pump to a specific Preciculture drivetrain.

The AHA10VO is a variable displacement axial piston pump built on a swashplate design, manufactured by Bosch Rexroth, one of the largest hydraulic component manufacturers in the world. It's an open-circuit pump, meaning it draws oil from a reservoir and delivers it to the hydraulic system rather than recirculating within a closed loop like a travel-drive pump would.

If you're sourcing a replacement, always confirm two things before ordering:

1. The exact Rexroth type code and control variant stamped on the original pump's nameplate

2. Whether the chassis uses a single AHA10VO or a tandem/combination pump (an AHA10VO paired with a second pump on a shared shaft), which is common on machines that need to run propulsion, steering, and implement circuits independently

Installation Considerations

Priming before start-up. Axial piston pumps can be damaged by dry running for even a few seconds. Fill the pump housing with clean hydraulic oil through the case drain port before the first start.

Case drain routing. The case drain line must run to a point in the reservoir below the oil level, with minimal restriction, to prevent shaft seal damage from back-pressure.

Fluid cleanliness. Piston pumps run tight internal clearances; contaminated oil is one of the leading causes of premature wear in this pump family. Confirm filtration meets Rexroth's specified ISO cleanliness code before commissioning.

Torque and alignment. Confirm coupling alignment and mounting bolt torque against the OEM chassis manual — misalignment shows up quickly as bearing wear or noise.

Q1: Is the HP9006 code a Rexroth part number?

A1: No. HP9006 is an equipment/application reference code used by parts suppliers and remanufacturers to identify which pump fits a specific Preciculture chassis configuration. The actual Rexroth part is identified by its own type code, stamped on the pump nameplate.

Q2: How long does an AHA10VO pump typically last?

A2: With clean, properly filtered oil and correct case-drain routing, these pumps commonly run for several thousand hours before internal wear requires attention. Contamination and dry-running incidents are the most common causes of early failure.

Q3:What is the price and delivery time of the AHA10VO hydraulic pump for the Preciculture HP9006 equipment？

A3: The specific price and delivery time will depend on the equipment model or specific product model you provide.
