The Multiquip EM23957 is a genuine OEM Reducer 4" X 2-1/2" X 47" DG Heavy Duty designed for the HHNG5 series ride-on power trowel. As a factory-sourced component, EM23957 is built to the exact dimensions and material specifications required for proper fit and function in these large-format mechanical trowels. DHS Equipment supplies this part direct, so you can be confident you are receiving the correct OEM reducer for your machine. Confirm your model against the HHNG5 fitment before ordering to ensure a match.
Key Features
- Heavy-Duty OEM Construction — Sourced directly from Multiquip, this reducer is manufactured to the heavy-duty material and dimensional standards required for the drive demands of large ride-on trowel applications.
- Exact Dimensional Spec: 4" x 2-1/2" x 47" — The specific bore, outlet, and length dimensions are critical to correct installation in the HHNG5 drivetrain; this OEM part matches those specs exactly without alteration.
- Fits HHNG5 Ride-On Power Trowels — Engineered specifically for the Multiquip HHNG5 8-foot heavy-duty mechanical ride-on trowel series.
- Sustained Power Transmission — A correctly functioning reducer maintains the proper torque transfer to the trowel blades; a worn or damaged unit causes inconsistent blade speed, vibration, and loss of finishing control.
- Genuine OEM Traceability — Part number EM23957 is a verified Multiquip OEM component, eliminating guesswork when cross-referencing against your parts manual or service record.
A reducer in a ride-on power trowel transfers and steps down rotational force from the drive system to the trowel blade assembly, allowing the blades to turn at the correct speed and torque for concrete finishing. On a large machine like the HHNG5, the reducer is subjected to continuous high-load operation, making heavy-duty construction essential for long service life. When a reducer wears or fails, operators typically experience irregular blade rotation, increased vibration, or complete loss of blade drive — any of which will interrupt finishing work and risk surface quality.
