Multiquip EM14328 Rocker Arm Assembly - OEM Replacement Part for C30HD Concrete Pumps

The rocker arm assembly is a critical component in the pumping mechanism of Multiquip C30HD concrete pumps, controlling the precise valve timing and hydraulic actuation required for reliable concrete delivery. This assembly coordinates the opening and closing of material valves during the pumping cycle, ensuring consistent flow rates and preventing backflow or pressure loss that can halt jobsite operations.

Designed specifically for the C30HD series equipped with Zenith engines, this rocker arm assembly maintains the mechanical advantage necessary for proper valve operation under the demanding conditions of concrete pumping. Worn or damaged rocker arm assemblies can result in erratic pumping action, reduced output capacity, increased hydraulic pressure, or complete pump failure. Regular inspection of rocker arm components should be performed during routine maintenance intervals to identify wear patterns, loose hardware, or misalignment before catastrophic failure occurs.

This assembly is compatible with the following Multiquip concrete pump models:

• C30HDGA
• C30HDN
• C30HDNI
• C30HDZ
