Key Features
- Genuine OEM Steel Construction — Fabricated from the same hydraulic-grade steel as the original, maintaining structural integrity under the vibration and load demands of ride-on trowel operation.
- Direct Bolt-In Replacement — Engineered to match the original mounting points and dimensions on HTN series trowels, so installation follows the standard service procedure without rework.
- HTN Series Fitment — Compatible with Whiteman HTN ride-on power trowels equipped with Kohler, Onan, or Honda engines.
- Radiator System Integrity — A solid, undamaged support tube keeps the radiator correctly positioned, preventing coolant line stress, vibration-induced cracking, and overheating during extended finishing runs.
- Superseded Part — Current Replacement is 26993 — Multiquip has issued an updated part number; confirm availability of 26993 to ensure you receive the current production component.
The hydraulic steel radiator support tube provides the structural mounting framework that holds the radiator in its correct position within the machine's cooling system. On a ride-on power trowel, engine heat management is critical — a misaligned or unsupported radiator is vulnerable to vibration fatigue, which can lead to coolant leaks, restricted airflow, and eventual engine overheating. Replacing a damaged or deteriorated support tube restores the radiator to its designed position and protects the broader cooling circuit from secondary damage.
