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 from Wacker Neuson and matches the exact specifications of the original part installed at the factory. Fitment covers a wide range of HI-series configurations including diesel, natural gas, LP, and dual-fuel variants across both trailer-mounted and skid-mounted heater platforms. Always confirm your model number before ordering to ensure correct application.
Key Features
- Genuine OEM Dimensional Accuracy — Manufactured to the exact thickness and material spec of the original, ensuring correct spacing and load distribution within the heater assembly.
- Drop-In Installation — Designed to seat and align exactly as the original, requiring no trimming, shimming, or improvised fitting during reinstallation.
- Broad HI-Series Compatibility — Fits HI750 (diesel, gas, dual-fuel, HD), HI900 (diesel, natural gas, dual-fuel, surge brake), and HI260 configurations across trailer and skid-mounted platforms.
- Maintains Heater Structural Integrity — A correctly fitted spacer plate keeps internal components properly separated and aligned; a worn or missing spacer can lead to contact between components, vibration damage, and premature wear.
- OEM Sourced for Assured Compatibility — Backed by Wacker Neuson's parts program, so the part number, geometry, and material grade match what was originally specified for your heater model.
A spacer plate is a precision-fit structural component used to maintain the correct gap or positional relationship between two adjacent 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 mounting hardware are held at the correct standoff distance, preventing metal-to-metal contact, reducing vibration transfer, and preserving the alignment that efficient combustion and airflow depend on. When a spacer plate is missing, worn, or incorrectly sized, adjacent components can shift, contact one another, or vibrate excessively — accelerating wear and potentially compromising heater output and reliability.
