The Multiquip EM50707 Connecting Rod ST80 is a genuine OEM Connecting Rod ST80 designed for the ST80 swing tube concrete pump. As a direct Multiquip OEM component, EM50707 is manufactured to the exact tolerances required to maintain proper piston stroke and pumping output in the ST80. Sourced directly through authorized Multiquip distribution, this part is the correct specification replacement for worn or damaged connecting rod assemblies on ST80 units.
Key Features
- OEM-Grade Structural Integrity — Engineered to the same load-bearing and dimensional tolerances as the original, ensuring the rod handles the cyclic compression forces of concrete pumping without deflection or premature fatigue.
- Direct-Fit for ST80 Concrete Pumps — Designed to install in the ST80 swing tube pump using the original mounting configuration, requiring no additional machining or fitment adjustment.
- Confirmed ST80 Compatibility — Fitment verified for the Multiquip ST80 series swing tube concrete pump; use part number EM50707 to confirm your application before ordering.
- Preserves Pumping Stroke Consistency — A correctly fitted connecting rod maintains proper piston travel, which directly affects pumping pressure and output volume — a worn rod causes stroke loss and uneven material flow.
- Genuine Multiquip OEM Part — Supplied as an authentic OEM replacement, ensuring material grade and geometry match the original component specification for the ST80 drivetrain.
The connecting rod in a concrete pump transfers the rotational or cyclic motion of the drive mechanism into the linear stroke that pushes concrete through the pumping cylinder. It is a high-stress component subjected to repeated compressive and tensile loading with every pump cycle. When a connecting rod wears, bends, or fails, the piston stroke becomes inconsistent, output pressure drops, and continued operation risks damage to surrounding pump components — making timely replacement critical to keeping the pump performing at full capacity.
