The Multiquip EM98294 Engine Deutz 74HP Tier 4 Final LS400/LS50 is a genuine OEM engine assembly designed for the LS400 and LS50 hydraulic-driven concrete pumps. As a direct OEM replacement sourced through Multiquip, EM98294 delivers the exact power output, emissions compliance, and dimensional fit required by these machines. This engine meets current EPA Tier 4 Final standards, making it the correct choice for operators working on regulated jobsites. If you need to verify fitment for your specific unit, contact the DHS Equipment team for support.

Key Features

  • Tier 4 Final Emissions Compliance — Meets current EPA Tier 4 Final requirements, ensuring your LS400 or LS50 pump stays compliant on regulated and permitted work sites.
  • Genuine OEM Deutz Powerplant — Sourced directly through Multiquip as an OEM assembly, this Deutz 74HP engine matches the original specification for combustion output, fuel delivery, and cooling integration on these concrete pump models.
  • Direct Engine Replacement for LS400 and LS50 — Engineered to fit the LS400 and LS50 hydraulic concrete pump platforms, with OEM-matched mounting geometry and auxiliary drive connections for a straight swap.
  • Sustained Hydraulic Drive Performance — At 74HP, this engine delivers the sustained power output needed to drive the hydraulic system that controls pumping pressure and output volume — a worn or underpowered engine will cause pressure drop and reduced material flow.
  • Emissions-Critical Component — As a Tier 4 Final engine, EM98294 includes the emissions control architecture required by federal regulations; using a non-compliant replacement engine can result in permit violations and equipment restrictions on regulated sites.

The engine is the primary power source for the LS-series hydraulic concrete pump, driving the hydraulic system that controls the pumping pistons, boom (where applicable), and ancillary functions. On a hydraulic-driven pump like the LS400 and LS50, the engine must deliver consistent horsepower to maintain stable hydraulic pressure — any loss of power directly reduces pumping capacity and can cause material to set in the line. A failed or end-of-life engine requires full replacement with a correctly rated, emissions-compliant unit to restore the machine to full working specification.
