- Sustained Pumping Output — A properly functioning rocker arm assembly maintains consistent valve actuation timing, preserving the pump's rated output pressure and volume per stroke.
- Verified Part Number — Order EM14328 with confidence knowing this is the correct Multiquip part number for this assembly across the supported C30HD series.
The rocker arm assembly is a critical component of the engine's valve train, transferring motion from the camshaft to the intake and exhaust valves so the engine can breathe correctly during each combustion cycle. When the rocker arm wears, cracks, or loses its pivot seat, valve timing becomes erratic, leading to loss of engine power, rough running, or the inability to start — all of which take a concrete pump out of service at the worst possible time. Replacing a worn or damaged rocker arm assembly with a correct OEM unit like the part restores proper valve actuation and returns the engine to its designed operating condition.
