J.C. Whitney JRV51040002 Power Steering Pump with Pulley OEM Replacement 8251738

The J.C. Whitney JRV51040002 is a direct-fit OEM replacement hydraulic power steering pump designed as a precise substitute for Volvo original equipment part number 8251738 (superseded by 8602734). This pump comes complete with the pulley pre-installed and is sold without a reservoir, making it a straightforward swap for worn or failing factory units.

The power steering pump is the heart of the hydraulic steering assist system. It pressurizes fluid from the power steering reservoir and delivers it to the steering rack or gear, providing the hydraulic force that makes turning the wheel effortless — even at low speeds or when parking. A failing pump commonly presents as a whining or groaning noise when turning, increased steering effort, or fluid leaks.

Key Features:

• Direct OEM replacement — engineered to match original factory specifications for fit and function
• Includes drive pulley — no separate pulley purchase required
• Reservoir not included — retains and reuses your existing reservoir
• Replaces Volvo OEM part number 8251738 / cross-reference KS01000091
• Superseded Volvo part number: 8602734
• Restores proper hydraulic pressure and smooth steering response

This pump is sold as an individual unit. Always flush and refill the power steering system with the manufacturer-specified fluid when replacing the pump to ensure optimal performance and longevity.
