Multiquip EM14329 Shaft Rocker Arm - OEM Replacement Part for C30HD Concrete Pumps

The shaft rocker arm is a critical mechanical component in the pumping assembly of Multiquip C30HD series concrete pumps, translating rotational motion from the drive system into the reciprocating action needed to move concrete through the pump cylinders. This precision-machined shaft ensures proper timing and coordination of the rocker arm mechanism, which directly controls the pump's hydraulic cylinders and concrete flow rate.

Designed specifically for the C30HD platform with Zenith engine configurations, this OEM shaft maintains the exact tolerances required for reliable high-pressure concrete pumping operations. Wear or damage to the rocker arm shaft can result in irregular pumping action, reduced output pressure, excessive vibration, or complete pump failure. Regular inspection of this component during scheduled maintenance intervals is essential for preventing costly downtime on job sites.

Compatible with the following Multiquip concrete pump models:

• C30HDGA
• C30HDN
• C30HDNI
• C30HDZ
