The Wacker Neuson is a genuine OEM Compression Spring designed for the EH 100 series electric demolition breakers, including the EH 100/240 and EH 100/230 configurations across multiple chuck sizes. As a factory-sourced component, the delivers the exact dimensional tolerances and spring rate required by the original design, ensuring proper function within the EH 100 breaker mechanism. This spring is confirmed to fit a range of EH 100 variants including 28x152, 28x160, and 32x160 tool shank configurations.
Key Features
- Matched Spring Rate for EH 100 Breakers — Wound to the exact coil dimensions and spring load specified for the EH 100 breaker family, maintaining the correct striking force and rebound cycle.
- Genuine OEM Sourcing — Manufactured to Wacker Neuson's original specifications, so you get the same part that came in the machine — not an approximation.
- Broad EH 100 Series Coverage — Fits EH 100/240 and EH 100/230 models across 28x152, 28x160, and 32x160 tool holder configurations, making this a widely applicable service part for EH 100 fleets.
- Critical to Consistent Impact Performance — A fatigued or broken compression spring causes irregular piston return, weakened impact energy, and accelerated internal wear. Replacing it restores full, consistent blow frequency.
- Correct Fitment for Drop-In Installation — Dimensioned to seat directly in the original spring pocket without modification, so the breaker can be returned to service quickly.
The compression spring in an electric demolition breaker serves as a key element of the reciprocating piston mechanism, storing and releasing energy to drive the tool shank into the work surface with each impact cycle. When this spring is correctly tensioned, the breaker delivers consistent blow energy and smooth operation through concrete, masonry, and other hard materials. As the spring fatigues or fractures, impact force drops noticeably, the piston return becomes erratic, and continued use accelerates wear on surrounding internal components — making timely replacement essential to protecting the wider breaker assembly.
