The Wacker Neuson Tension Spring is a genuine OEM component designed for the ML440, ML240, ML425, and ML225 series Light Towers and Multifunction Floodlight Towers. As a factory-sourced part, it is manufactured to the exact specifications required by Wacker Neuson, ensuring a direct, correct-fit replacement every time. This tension spring is a critical component in the light tower's mechanical assembly, and selecting the right part by number is the surest way to get your equipment back in service fast. Confirm your model number against the fitment list below before ordering to ensure compatibility with your specific unit.
Key Features
- OEM Spring Tension Integrity — Manufactured to Wacker Neuson's specified load and extension rating, so the spring delivers the correct mechanical force from day one without calibration or adjustment.
- Drop-In Replacement — Engineered to match the original mounting points and hook geometry, allowing straightforward installation without modification to surrounding hardware.
- Broad Light Tower Compatibility — Fits multiple ML-series configurations including ML440, ML240, ML425, and ML225 Light Towers and Multifunction Floodlight Towers across numerous build variants.
- Consistent Mechanical Return — A properly tensioned spring maintains reliable positioning and movement of the components it supports; a worn or weakened spring can cause misalignment, excessive play, or failure to return to the correct position.
- Genuine Wacker Neuson Part — Sourced directly through the Wacker Neuson OEM supply chain, carrying the part number 5000404308 for straightforward verification against your machine's parts diagram.
A tension spring stores and releases mechanical energy to hold components under load, maintain positioning, or return a part to its resting state after movement. In light tower applications, tension springs are commonly used to support adjustable arms, latching mechanisms, or mast assemblies where consistent spring force is essential for smooth, controlled operation. When a tension spring stretches beyond its rated capacity, loses elasticity, or breaks, the components it controls can become loose, unresponsive, or prone to unintended movement — affecting both the usability and the structural integrity of the tower assembly.
