The Multiquip 20364 Connecting Rod is a genuine OEM component designed for Mayco C30HD-series concrete pumps, including the C30HD, C30HDG, C30HDZ, C30HDGA, C30HDN, C30HDNI, C30HDNI Precision, and C30HDNI Zenith. As a direct OEM replacement, this connecting rod meets the original design specifications set by Multiquip, ensuring a correct installation within the pump's drive mechanism. Sourced directly through authorized supply channels, part number 20364 is the verified replacement for these Mayco pump families. If your concrete pump is showing signs of drive wear or internal reciprocating failure, replacing the connecting rod with the correct OEM part is the reliable path back to full operation.
Key Features
- Genuine OEM Construction — Manufactured to the original material and dimensional standards for the C30HD-series reciprocating pump drive, ensuring proper load transfer and fatigue resistance under continuous pumping cycles.
- Direct Drop-In Replacement — Engineered to match the original bore geometry and rod length, allowing installation without modification to the crankcase or piston assembly.
- Broad C30HD-Series Compatibility — Confirmed fitment across C30HD, C30HDG, C30HDZ, C30HDGA, C30HDN, C30HDNI, C30HDNI Precision, and C30HDNI Zenith concrete pump models.
- Restored Pumping Consistency — A sound connecting rod maintains accurate piston stroke length and timing, which directly controls output pressure and concrete delivery rate. A worn or cracked rod causes erratic pressure and pump failure.
- Verified Part Number — Part 20364 is the OEM-designated connecting rod for these Mayco models, eliminating guesswork when ordering critical internal engine components.
The connecting rod links the crankshaft to the piston inside the pump's power unit, converting the rotational motion of the engine into the linear stroke that drives concrete through the pump. It is one of the highest-stress components in the drive assembly, absorbing both compression and tension forces on every stroke cycle. When a connecting rod cracks, bends, or develops bearing wear at either end, the result is loss of stroke consistency, unusual knocking from the power unit, and — if left unaddressed — catastrophic internal damage to the crankcase or piston assembly.
