The Wacker Neuson Driven Blower Pulley is a genuine OEM component designed for the HI750 and HI1000 series indirect fired air heaters, including diesel, gas, and dual-fuel DGM configurations. Sourced directly from Wacker Neuson, this part carries the exact specifications required for correct belt engagement and blower operation across the full range of compatible heater models. Whether you're servicing an HI750G, HI750D, HI750GM, or an HI1000 unit, part number is the factory-correct replacement that installs without guesswork. Keeping your indirect heater's air delivery system performing at full output starts with the right driven pulley — and this is it.
Key Features
- Genuine OEM Belt Engagement Geometry — Machined to the exact groove profile and diameter specified by Wacker Neuson, ensuring correct belt tracking and tension on the blower drive system.
- Direct Drop-In Replacement — Matches the original mounting bore and hub dimensions, so the pulley seats and fastens to the blower shaft exactly as the factory unit did.
- Broad HI750 and HI1000 Series Coverage — Confirmed fitment across HI750G, HI750D, HI750GM, HI750GM HD, and HI1000 diesel, gas, and DGM heater models, including skid-mounted and surge-brake variants.
- Sustained Airflow Output — A correctly sized driven pulley maintains the designed blower RPM, delivering consistent heated air volume and temperature at the duct outlet under continuous operation.
- Wear-Resistant Construction — Built to handle the continuous rotational load and belt friction demands of indirect heater blower systems operating in cold-weather job conditions.
The driven blower pulley is a core component of the belt-drive system that spins the heater's blower fan. It receives rotational power from the drive belt connected to the engine or motor output, transferring that motion to the blower shaft to move heated air through the unit and out to the work area. When the pulley wears, cracks, or loses its groove profile, belt slip increases, blower speed drops, and heat output falls well below the unit's rated capacity — making prompt replacement essential to keeping the heater functioning as intended.
