The Wacker Neuson Axle is a genuine OEM Axle designed for the HI 400HD G, HI 400HD D, and HI 120HD Indirect Air Heater series. As a factory-authorized component, it is manufactured to the same specifications as the original part fitted at the time of production, ensuring a direct, hassle-free installation. This Axle is confirmed compatible across the HI 400HD and HI 120HD heater lines, making it the right call for service technicians and equipment owners keeping these units in working order.
Key Features
- OEM-Grade Dimensional Accuracy — Manufactured to original tolerances, ensuring the Axle seats and rotates correctly within the heater's wheel and frame assembly without adjustment.
- Direct Drop-In Installation — Matches the original mounting points and bore dimensions of the HI 400HD G, HI 400HD D, and HI 120HD, so the swap is straightforward with standard tools.
- Confirmed Fitment Across HI 400HD and HI 120HD Series — Covers the HI 400HD G, HI 400HD D, and HI 120HD Indirect Air Heater models, giving you confidence you are ordering the correct part for your machine.
- Structural Integrity Under Load — A sound Axle keeps the heater's wheels tracking correctly and the unit rolling freely on the worksite; a worn or bent Axle can cause instability and make maneuvering the unit difficult and unsafe.
- Genuine Wacker Neuson Part — Sourced directly through the authorized parts network, so the part number, form, and fit match what left the factory on your original machine.
The Axle on an indirect air heater serves as the central shaft that supports the unit's wheel assembly, allowing the heater to be rolled and repositioned across the worksite with control and stability. It bears the rolling load of the machine and keeps the wheels properly aligned and secured. When an Axle bends, wears, or becomes damaged, the wheels can wobble, seize, or detach, making the unit difficult and unsafe to move — replacing it promptly restores full mobility and keeps the heater operating as intended.
