The Multiquip 506187 Hydraulic Pump is a genuine OEM component designed for the AR13 series ride-on asphalt rollers, including the AR13HC, AR13HA, AR13HAR, AR13H, and AR13D. As a direct OEM replacement, this part is built to the exact specifications of the original unit, ensuring correct flow rates, pressure ratings, and mounting compatibility with no guesswork involved. Sourced directly through Multiquip's authorized parts network, the 506187 is the correct service part for keeping your AR13 series roller operating at full hydraulic capacity. Verify your model against the fitment list above before ordering to confirm compatibility.
Key Features
- OEM-Matched Hydraulic Output: — Built to the same flow and pressure specifications as the original pump, maintaining proper hydraulic system performance throughout the roller's operating range.
- Direct Bolt-In Replacement: — Matches the original mounting configuration and port layout of the AR13 series hydraulic system, allowing straightforward installation without custom adapters.
- Confirmed AR13 Series Fitment: — Verified for use on AR13HC, AR13HA, AR13HAR, AR13H, and AR13D ride-on asphalt rollers.
- Protects Downstream Hydraulic Components: — A properly functioning pump maintains consistent pressure across the hydraulic circuit, preventing premature wear on motors, valves, and cylinders caused by pressure loss or cavitation.
- Genuine OEM Part: — Supplied as an authentic Multiquip replacement under part number 506187, meeting the same standards as the pump installed at the factory.
The hydraulic pump is the heart of the roller's hydraulic system, converting mechanical energy from the engine into pressurized fluid flow that drives the drum propulsion, steering, and vibratory functions. When the pump wears or fails, the machine may lose drive power, respond sluggishly to directional inputs, or lose vibratory force entirely — directly impacting compaction quality and productivity on the paving surface. Replacing a failing pump promptly with the correct OEM unit restores full system pressure and prevents collateral damage to other hydraulic components downstream.
