The Wacker Neuson is a genuine OEM Belt Pulley designed for the E1250, E3000, E2200, and HSH380 series hydronic surface heaters and ground heaters. Sourced directly from Wacker Neuson, this part meets the exact specifications of the original component installed at the factory. Compatible across a wide range of configurations including diesel, natural gas, and LP/NG variants, the Belt Pulley is the correct replacement for both standard and premium heater builds. Whether you are servicing an HSH380S, an E3000 Ground Heater, or an E1250P Hydronic Heater, this pulley restores proper drive system function and gets your equipment back to full operation.
Key Features
- Genuine OEM Dimensional Accuracy — Manufactured to Wacker Neuson's original pulley diameter and bore tolerances, ensuring correct belt tension and drive alignment from installation.
- Direct-Fit Replacement — Drops into the existing drive assembly without modification, matching the original mounting interface on all covered heater configurations.
- Broad Series Compatibility — Fits E1250S, E1250P, E2200, E3000, HSH380B, and HSH380S models across diesel, natural gas, LP/NG, and generator-equipped variants.
- Maintains Belt Drive Efficiency — A correctly sized and seated pulley keeps belt slip and wear to a minimum, preserving consistent circulation pump output and heater performance.
- Verified Wacker Neuson Part Number — Part number 1000324979 is cross-referenced directly to the affected machine series, eliminating guesswork when ordering for mixed fleets.
The belt pulley transfers rotational drive from the motor to the circulation pump or blower system within the hydronic heater, using a drive belt to transmit power between the two components. It must maintain the correct diameter and alignment to keep belt tension within spec — a worn, cracked, or undersized pulley causes belt slippage, uneven wear, and eventual loss of fluid circulation or airflow, which can lead to heater shutdown. Replacing a damaged pulley with the correct OEM part restores full drive efficiency and protects the belt from premature failure.
