The Multiquip 20870 Radiator Support Bracket is a genuine OEM component designed for the HHN31V ride-on power trowel. Sourced directly from Multiquip, this bracket matches the original specification and mounts without modification to the HHN31V chassis. Keeping the radiator securely in position is critical on a heavy-duty finishing machine, and this OEM replacement ensures the correct structural integrity is restored. If you're servicing an HHN31V and need a bracket you can trust to fit first time, the part is the correct part.
Key Features
- Genuine OEM Structural Integrity — Manufactured to the exact material grade and mounting geometry of the original bracket, ensuring the radiator is held securely under working loads.
- Direct Bolt-In Replacement — Engineered to align with existing mounting points on the HHN31V frame, so installation is straightforward with no drilling or fabrication.
- Confirmed HHN31V Fitment — Part 20870 is verified for the Whiteman HHN31V 8-foot heavy-duty ride-on power trowel series.
- Protects Cooling System Position — A correctly mounted radiator bracket keeps the cooling core stable and properly aligned with airflow, helping the engine maintain operating temperature during extended finishing runs.
- Prevents Vibration-Induced Damage — Ride-on trowels generate significant vibration during operation; a sound support bracket prevents radiator movement that can stress hose connections and cooling fittings over time.
The radiator support bracket is a structural mounting component that holds the engine's radiator securely in place within the machine's frame. On a high-vibration piece of equipment like the HHN31V ride-on trowel, this bracket absorbs movement and keeps the radiator core properly positioned so coolant flow and airflow remain unobstructed. When the bracket is cracked, bent, or missing, the radiator can shift under load — placing stress on hoses, fittings, and the core itself — which can lead to coolant leaks or overheating if left unaddressed.
