Multiquip EM14846 Cam Rocker Arm Weldment - OEM Replacement Part for C30HD Concrete Pumps

The cam rocker arm weldment is a critical component in the pumping mechanism of Multiquip C30HD series concrete pumps, converting rotational motion from the engine into the reciprocating action needed to drive concrete through the delivery system. This precision-engineered weldment ensures proper timing and force distribution during the pumping cycle, directly affecting pump performance and concrete flow consistency.

Designed specifically for the C30HD platform, this rocker arm assembly is built to withstand the extreme forces and continuous duty cycles inherent in commercial concrete pumping operations. Signs that this component may need replacement include irregular pumping action, unusual vibration or noise during operation, reduced pumping efficiency, or visible wear on the cam contact surfaces. Regular inspection of the rocker arm mechanism should be part of your preventive maintenance routine to avoid unexpected downtime on job sites.

Compatible with the following Multiquip concrete pump models:

• C30HDGA (Zenith 416 Gamma Gasoline Engine)
• C30HDN
• C30HDNI
• C30HDZ
