The Multiquip EM60701 Hatz Diesel Engine 57HP is a genuine OEM power unit designed for the ST-45HRM concrete pump. As a direct OEM replacement, this engine is sourced and validated by Multiquip to meet the original build specification of the ST-45HRM, ensuring the machine performs as it was engineered to. DHS Equipment supplies this as an authorized Multiquip OEM part, so you can order with confidence knowing the part number matches your machine's requirements. If you're rebuilding or re-powering an ST-45HRM, the part is the correct engine assembly to specify.
Key Features
- Genuine Hatz Diesel Power: — OEM-spec Hatz diesel engine delivering 57HP output — the same powerplant Multiquip installs at the factory for full ST-45HRM performance.
- Direct Engine Replacement: — Engineered to mount and connect to the ST-45HRM drivetrain as a drop-in unit, matching original mounting points and output shaft configuration.
- Confirmed ST-45HRM Fitment: — Validated for the Multiquip ST-45HRM concrete pump; verify your model code before ordering to ensure an exact application match.
- Sustained Pumping Output: — A correctly specified engine maintains consistent hydraulic pressure and pumping cycle performance — an underpowered or worn engine causes output loss, pressure drops, and premature pump component wear.
- Fuel System Integrity: — Diesel engine assemblies include precision-toleranced fuel delivery components; an OEM unit ensures correct injection timing and combustion efficiency critical to safe continuous operation on the jobsite.
The engine is the primary power source for the ST-45HRM concrete pump, driving the hydraulic system that pushes concrete through the delivery line. At 57HP, this Hatz diesel unit generates the torque and sustained output needed to maintain steady pumping rates under load. When an engine loses compression, develops fuel delivery faults, or fails outright, the pump ceases to function — making correct engine specification and a quality replacement essential to keeping the machine operational.
