The Wacker Neuson Pulley is a genuine OEM component designed for the HI260 indirect-fired air heater series. As a factory-sourced part, it is manufactured to the exact tolerances and specifications required for proper belt-drive operation on the HI260 Heater Oil With Tank and the standard HI260 model. Fitting directly onto the original drive assembly, this pulley restores correct belt alignment and tension so the heater runs at full heating output without slippage or vibration.
Key Features
- Genuine OEM Dimensional Accuracy — Machined to the exact bore diameter, groove profile, and keyway specification required for the HI260 belt-drive system, ensuring correct belt seating from the first run.
- Direct-Fit Replacement — Mounts to the original drive shaft position on the HI260 without modification, matching the factory bolt pattern and hub interface.
- Confirmed HI260 Compatibility — Verified for the HI260 Heater Oil With Tank (5200018503) and the HI260 (5200018504), covering both common configurations of this indirect-fired heater.
- Sustained Heating Output — A correctly sized and balanced pulley maintains consistent blower speed, which is critical for steady, uninterrupted heat delivery on cold-weather jobsites.
- Reduced Belt Wear — Proper groove geometry prevents belt tracking errors that cause premature belt fraying and unexpected heater shutdowns during operation.
The pulley is a core component of the HI260's belt-drive system, transferring rotational power from the engine to the blower that forces heated air through the heat exchanger and out into the work area. When the pulley wears, cracks, or loses its groove profile, belt slip increases, blower speed drops, and heat output falls — or the belt fails entirely, taking the heater offline. Replacing a worn pulley with the correct OEM part restores the designed power-transfer ratio and keeps the blower running at the speed the combustion system was calibrated to support.
