The Multiquip 912239014 Engine GX390UT2-SM32 is a genuine OEM engine assembly designed for the MRH800GS walk-behind roller. As a direct OEM replacement, this engine is sourced from Multiquip's authorized supply chain and built to the same specification as the unit that left the factory. It is the correct engine for MRH800GS roller applications, giving operators confidence in both fitment and long-term performance.

Key Features

  • Genuine OEM Engine Assembly — Sourced directly through Multiquip's authorized parts program, ensuring the GX390UT2-SM32 spec is met exactly as engineered for this application.
  • Direct-Fit Replacement for MRH800GS — Matches the original mounting configuration and output spec of the MRH800GS walk-behind roller for a straightforward swap.
  • Correct Power Output for Roller Operation — The GX390UT2-SM32 engine delivers the torque and RPM range the MRH800GS drum drive system depends on for consistent compaction performance.
  • Complete Engine Unit — Supplied as a full engine assembly, reducing the complexity of sourcing individual sub-components during a major engine replacement.
  • OEM Part Number Verified — Part number 912239014 is confirmed against Multiquip's official parts documentation for the MRH800GS, eliminating guesswork at the parts counter.

The GX390UT2-SM32 is the Honda-powered gasoline engine that drives the vibratory drum system on the MRH800GS walk-behind roller. It provides the mechanical power needed to propel the machine and maintain drum vibration frequency, both of which directly affect compaction quality on asphalt and granular surfaces. When the engine loses power, fails to start, or runs poorly, compaction output becomes inconsistent — replacing it with the correct OEM unit restores full operational capacity.
