Multiquip 506182 Coupling PSI Test SMK20-9/16UNF-VE VR36H - OEM Replacement Part

This hydraulic pressure test coupling connects a 5,000 psi pressure gauge to the manifold block test ports, allowing technicians to diagnose hydraulic system performance on ride-on roller equipment. Essential for performing forward/reverse hydraulic pressure tests and vibration system diagnostics, this coupling ensures accurate pressure readings during maintenance procedures.

During standard hydraulic pressure testing, this coupling installs to quick disconnect test port 1 on the manifold block. With the engine running at full throttle, normal operating pressure should range between 800-1,000 psi when the vibration control is activated. The coupling features a 9/16 UNF thread connection compatible with the SMK20 test port configuration specified in Multiquip service procedures.

This test coupling is critical for troubleshooting low vibration issues, slow steering response, and hydraulic pressure verification. Regular pressure testing using this coupling helps identify defective relief valves, broken motor couplers, and contaminated cylinders before they cause equipment failure.

• AR13D
• AR13H
