The Wacker Neuson Stack Guard Hinge is a genuine OEM component designed for the HI260, HI750, HI900, and HI1000 series indirect fired air heaters. As a direct OEM replacement, this hinge is manufactured to the exact specifications of the original part, ensuring a correct, trouble-free installation with no improvisation required. It is compatible across a wide range of HI-series configurations including diesel, natural gas, and dual-gas models in both skid-mounted and trailer-mounted setups. Keeping your heater's stack guard properly hinged and secured is essential for safe, efficient field operation through demanding conditions.
Key Features
- Genuine OEM Construction — Manufactured by Wacker Neuson to the same material and dimensional tolerances as the original, so the hinge moves and seats exactly as intended on the stack guard assembly.
- Direct-Fit Replacement — Matches the original mounting points and hardware interface on HI-series stack guards, dropping in with existing fasteners and no rework to surrounding components.
- Broad HI-Series Compatibility — Verified fitment across HI260, HI750 (gas, diesel, and DGM variants), HI900 (diesel, gas, DGM, and surge brake models), and HI1000 (diesel, gas, and DGM configurations).
- Maintains Stack Guard Function — A correctly operating hinge keeps the stack guard properly positioned, protecting exhaust components and preserving the structural integrity of the heater's flue system under continuous run conditions.
- Safety-Critical Exhaust Protection — The stack guard shields personnel and surrounding equipment from exhaust heat; a failed or missing hinge can allow the guard to shift out of position, creating a burn and fire hazard on the worksite.
The stack guard hinge is the pivot hardware that allows the stack guard cover to open, close, and lock securely over the exhaust flue of an indirect fired air heater. It keeps the guard aligned against wind load, vibration, and repeated service access without loosening or distorting. When this hinge wears, bends, or fails, the stack guard can shift or fall free, exposing the hot flue stack and creating a safety risk for anyone working near the unit.
