Multiquip 806665 Coupling Assembly - OEM Replacement Part for Concrete Pumps

The coupling assembly connects and transfers rotational power between the engine and hydraulic pump system in trailer-mounted concrete pumps, ensuring reliable power transmission during high-volume pumping operations. This critical drivetrain component maintains proper alignment and absorbs shock loads that occur during concrete delivery.

Designed specifically for demanding concrete pumping applications, this coupling assembly must withstand the continuous torque generated by the 74.5 horsepower Hatz Turbo Diesel engine operating at 3,000 rpm. Regular inspection of this assembly is essential as part of your preventive maintenance program—check all fasteners periodically for tightness as recommended in the maintenance schedule to prevent coupling failure that could result in costly downtime on the job site.

Failed or worn coupling assemblies can cause vibration, unusual noise, loss of pumping pressure, or complete power transmission failure. Replacing this component with genuine OEM parts ensures proper fit, durability, and continued reliable operation of your concrete pumping equipment.
