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 factory replacement, this spacer plate installs exactly as the original, maintaining correct component alignment and clearance within the heater assembly. It is compatible across a broad range of HI-series configurations including diesel, natural gas, LP, and dual-fuel variants — covering both trailer-mounted and skid-mounted units. When a spacer plate wears, cracks, or goes missing, internal component alignment can shift, affecting heater performance and potentially causing accelerated wear on surrounding parts; replacing it with the correct OEM part restores the assembly to proper specification.
Key Features
- Genuine OEM Dimensional Accuracy — Manufactured to exact Wacker Neuson tolerances, ensuring the correct standoff distance and load distribution within the heater assembly.
- Drop-In Replacement — Matches the original mounting pattern and thickness, allowing straightforward installation without modification to adjacent hardware.
- Broad HI-Series Compatibility — Fits HI750G, HI750D, HI750GM, HI750GM HD, HI900D, HI900G, HI900DGM, and HI260 indirect-fired air heater configurations, including skid-mounted and trailer-mounted units.
- Protects Surrounding Components — Maintains proper spacing between mating parts, preventing metal-to-metal contact, misalignment, and premature wear in the heater drivetrain or burner assembly.
- Multi-Fuel Application Coverage — Supports diesel, natural gas, LP, and dual-fuel HI-series heater variants, making it a versatile stock item for fleet service operations.
A spacer plate is a precision-machined component used to maintain a defined gap or alignment between two mating parts within an assembly. In indirect-fired air heaters like the HI750 and HI900 series, correct spacing is critical to ensuring that rotating or pressurized components operate within their designed clearances — preventing binding, uneven load, and heat buildup. When a spacer plate is damaged or missing, the components it separates can shift out of alignment, leading to accelerated wear, vibration, or failure of the surrounding assembly.
