The Wacker Neuson is a genuine OEM Engine Sheave Pulley designed for the HP50, HP100, HPG50, and HPG100 series vibratory truss screed power sections. As a factory-sourced component, the is manufactured to the same specifications as the original part, ensuring correct belt alignment and drive engagement straight out of the box. This pulley fits both standard and gasoline-powered variants across the HP and HPG families, including the HPG100A, HP50A, HP100A, and HPG50A models. When your screed drive system needs attention, sourcing the genuine Wacker Neuson means you are installing a part built to perform exactly as the original did.
Key Features
- Genuine OEM Pulley Geometry — Machined to the exact groove profile and bore dimensions of the original, so belt tension and tracking are correct from the first run.
- Direct Bolt-On Replacement — Matches the original mounting interface on the engine output shaft, requiring no shimming or adaptation during installation.
- Broad HP and HPG Series Coverage — Confirmed fit for HP50, HP50A, HP100, HP100A, HPG50, HPG50A, HPG100, and HPG100A vibratory truss screed power sections.
- Sustained Drive-Belt Performance — A correctly sized sheave maintains proper belt speed and tension, protecting both the belt and the driven screed components from premature wear.
- Factory-Sourced Part — Supplied through the Wacker Neuson genuine parts program, so provenance and dimensional accuracy are assured.
The engine sheave pulley sits on the engine output shaft and transfers rotational power to the screed's drive belt and vibration system. Its groove diameter and profile directly control belt speed and tension — if the pulley is worn, cracked, or incorrectly sized, the belt will slip, wear unevenly, or jump, causing inconsistent vibration output and potential damage to the screed head. Replacing a damaged or worn sheave pulley with the correct OEM part restores the precise power transfer the screed was engineered to deliver.
