Multiquip EM14410 Holder Ring & Felt - OEM Concrete Pump Replacement Part

The holder ring and felt assembly provides critical wear protection and sealing for the cam roller mechanism in Multiquip C30HD series concrete pumps. This component ensures the cam roller rides smoothly on the cam profile, preventing operational issues that can arise from insufficient line back-pressure, cavitation, or oversized aggregate passage through the valving system.

When the cam roller fails to ride smoothly on the cam profile, it often indicates worn felt or a damaged holder ring. This can cause the pump to skip or operate erratically, particularly with wet mixes using minimal hose length. The felt component within this assembly maintains proper lubrication and reduces friction between moving parts in the crankshaft and cam assembly, which is essential for reliable pumping performance and extended component life.

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

• C30HDGA
• C30HDN
• C30HDNI
• C30HDZ
