Multiquip 507860 Adapter Pump B81820-0790K VR36H - OEM Replacement Part

This adapter pump component serves as a critical interface in the hydraulic system of Multiquip ride-on rollers, connecting the hydraulic pump assembly to the manifold block that controls hydraulic pressure distribution. The hydraulic system on these compaction rollers operates both the closed-loop hydrostatic drive circuit and the open-loop vibration and steering circuits, requiring reliable pump connections to maintain proper system pressure and component operation.

The hydraulic manifold assembly controls flow to drive motors, vibration systems, and the steering cylinder, with the system designed to operate using ISO 46 anti-wear hydraulic fluid. Proper pump adapter function is essential for maintaining hydraulic pressure throughout the system, preventing issues such as low vibration amplitude, slow steering response, or loss of drive function. During hydraulic system maintenance and pressure testing procedures, this adapter ensures secure connections between the pump and manifold assembly.

Compatible with the following Multiquip ride-on roller models:

• AR13D
• AR13H
• AR13HA
• AR13HA/AR13HAR
