The Multiquip 12100H7200 Connection Rod Assembly is a genuine OEM replacement designed for C30HDNI, C30HDN, C30HDNI Precision, and C30HDNI Zenith Mayco concrete pumps. As a factory-sourced component, it meets the exact specifications of the original part, ensuring a direct, trouble-free installation. This assembly is the correct replacement for C30HDN and C30HDNI series machines, giving operators confidence in fitment accuracy before the part even arrives on site.
Key Features
- Genuine OEM Construction — Manufactured to the original tolerances and material specifications required for consistent stroke motion and load transfer in a concrete pump application.
- Direct Bolt-In Replacement — Engineered to match the mounting geometry and pin dimensions of the original assembly, slotting directly into the C30HDN and C30HDNI pump drive train.
- Broad C30 Series Compatibility — Confirmed fitment across C30HDN, C30HDNI, C30HDNI Precision, and C30HDNI Zenith concrete pump variants.
- Sustained Pumping Consistency — A correctly functioning connection rod assembly maintains precise piston stroke length; a worn or damaged rod introduces erratic output pressure and accelerated wear on adjacent drive components.
- Verified Part Number — Part number 12100H7200 cross-references directly to these Mayco pump models, eliminating guesswork when sourcing a replacement for the C30HDNI or C30HDN.
The connection rod assembly transmits rotational force from the crankshaft into the linear back-and-forth motion that drives the piston inside a concrete pump. This reciprocating action is what generates the pressure needed to push concrete through the delivery line. When the connection rod wears, bends, or fails, the piston stroke becomes inconsistent, output pressure drops, and the pump may become inoperable — making timely replacement critical to keeping a pour on schedule.
