As a factory-sourced part, the is manufactured to the exact material and dimensional specifications required by Wacker Neuson for these machines.

Key Features
- OEM Spring Rate Accuracy — Manufactured to the exact coil geometry and spring rate specified by Wacker Neuson, ensuring correct tension and compression behavior within the assembly.
- Direct-Fit Replacement — Engineered to seat and locate identically to the original part, fitting into the existing mounting position without alteration.
- Broad Backhoe Loader Compatibility — Verified fitment across BL742, BL744, BL744c, and BL744 EX series Wacker Neuson Backhoe Loaders.
- Sustained Assembly Performance — A correctly rated inner spring maintains consistent load response in the surrounding mechanism; a fatigued or broken spring causes erratic operation, uneven force distribution, and accelerated wear on adjacent components.
- Genuine OEM Sourcing — Supplied directly through the Wacker Neuson parts network, so you receive the same component installed at the factory — not an approximation.
An inner spring provides controlled resistance and return force within a mechanical assembly, holding components under the correct preload and ensuring they return reliably to their resting position after each cycle. In backhoe loader applications, a spring operating at the wrong rate or one that has fatigued over time can cause sluggish or inconsistent response in the mechanism it supports, placing additional stress on surrounding hardware. Replacing a worn inner spring promptly with a correctly specified OEM part restores the assembly to its designed operating behavior and prevents secondary wear from developing.
