The Wacker Neuson Spacer Plate is a genuine OEM component designed for the HI750, HI900, and HI260 series indirect-fired air heaters. As a direct OEM replacement, this spacer plate is sourced and verified to Wacker Neuson's original specifications, ensuring it installs exactly as the factory part did across diesel, natural gas, propane, and dual-fuel DGM configurations. Compatible fitment spans a wide range of HI-series heater variants including skid-mounted, surge-brake, and mobile trailer-mounted units. Whether you're servicing a HI750G, HI900D, or HI260 oil-fired heater, part number is the correct OEM spacer plate to have on hand.
Key Features
- Genuine OEM Dimensional Accuracy — Manufactured to Wacker Neuson's original tolerances, ensuring correct spacing and load distribution within the heater assembly without rework or shimming.
- Drop-In Installation — Matches the original mounting footprint and thickness, allowing straightforward swap-out during routine service or component replacement.
- Broad HI-Series Compatibility — Confirmed fitment across HI750 (diesel, gas, DGM, HD surge), HI900 (diesel, natural gas, DGM, skid-mount variants), and HI260 oil-fired heater models.
- Structural Integrity Under Thermal Cycling — Indirect-fired heaters operate through repeated heat-up and cool-down cycles; a correctly fitted spacer plate maintains proper component alignment and prevents stress concentration on adjacent parts.
- Covers Multiple Fuel Configurations — A single part number serves diesel, natural gas, LP, and dual-fuel DGM variants across both mobile and skid-mounted HI-series platforms, simplifying parts inventory for fleet service.
A spacer plate is a precision-dimensioned component used to establish and maintain the correct gap or offset between two mating parts within an assembly. In indirect-fired air heaters like the HI750 and HI900 series, spacer plates ensure that heat exchanger components, burner assemblies, or structural panels are held at the correct relative position during operation. When a spacer plate wears, cracks, or goes missing, adjacent components can shift out of alignment, leading to uneven stress distribution, accelerated wear on surrounding hardware, or improper sealing between sections. Replacing a damaged or missing spacer plate promptly restores the mechanical relationship between parts and protects the broader heater assembly from secondary damage.
