The Multiquip EM805876 Zenith 71.3 HP Engine is a genuine OEM power plant designed for the LS300G hydraulic-driven concrete pump. As a factory-sourced OEM component, it delivers the correct displacement, power output, and mounting configuration required to restore full concrete pumping capacity to your LS300G. DHS Equipment supplies this engine direct from Multiquip, so you receive an authentic replacement backed by OEM traceability — no guesswork on compatibility.
Key Features
- Zenith Engine Authenticity — Sourced directly from Multiquip as a genuine OEM unit, matching the original Zenith 71.3 HP specification the LS300G was engineered around.
- Correct Power Rating for Hydraulic Drive — At 71.3 HP, this engine delivers the sustained output needed to drive the LS300G's hydraulic system under continuous pumping loads without underpowering the circuit.
- Direct Mount Compatibility — Engineered to match the OEM mounting footprint, fuel connections, and output shaft configuration of the LS300G, supporting a straightforward swap with correct torque and alignment.
- Sustained Pumping Performance — A properly specified engine keeps hydraulic pressure consistent across the pump cycle, maintaining concrete output volume and reducing pressure drop during high-demand pours.
- Fits LS300G Concrete Pump — Verified fitment for the Multiquip LS300G hydraulic concrete pump series.
The engine is the primary power source for the LS300G's hydraulic drive system, converting fuel combustion into the rotational force that pressurizes the hydraulic circuit and drives the concrete pumping mechanism. Without a correctly rated and properly functioning engine, the hydraulic system cannot maintain the pressure required to move concrete through the line — resulting in erratic output, pump stalls, or a complete loss of pumping function. Replacing a worn or failed engine with the correct OEM unit restores the machine to its original hydraulic performance specification and ensures the pump operates as designed under job-demand conditions.
