The Wacker Neuson Guide Bush is a genuine OEM component designed for EH 100 series electric breakers and electric hammers, covering 28x152, 28x160, and 32x160 tool configurations. As a direct OEM replacement, this part is manufactured to the same tolerances and material standards as the original, ensuring the chisel or tool steel seats and travels correctly within the breaker housing. Confirmed fitment spans multiple EH 100 variants including the EH 100/230 and EH 100/240 models, as well as BR and US market configurations. Verify your tool diameter and stroke specification against part number before ordering to confirm the right fit for your machine.
Key Features
- OEM-Spec Bush Material: — Manufactured to the same bore tolerancing and surface hardness as the original, ensuring the tool steel moves freely without excessive side-play or premature wear.
- Drop-In Replacement: — Installs directly into the EH 100 breaker housing the same way the factory part does, with no machining or adaptation needed to seat correctly.
- Broad EH 100 Series Fitment: — Covers EH 100/230 and EH 100/240 electric breakers and electric hammers across 28x152, 28x160, and 32x160 tool shank configurations, including BR and US variants.
- Consistent Chisel Guidance: — A correctly functioning guide bush keeps the tool steel aligned on every stroke; a worn bush allows lateral movement that accelerates internal wear and reduces breaking efficiency.
- Genuine Wacker Neuson Part: — Sourced directly through the Wacker Neuson OEM supply chain and carries the Wacker Neuson part number 5000205440 for straightforward dealer and warranty cross-reference.
The guide bush is a hardened sleeve fitted inside the breaker barrel that supports and aligns the tool steel — the chisel or moil point — as it reciprocates during operation. It controls the lateral movement of the tool shank, keeping each power stroke directed cleanly into the work material rather than being lost to side-load. When the guide bush wears, the tool steel begins to rock inside the barrel, accelerating wear on the breaker's internal components, reducing impact energy transfer, and eventually causing damage to the tool retainer and piston assembly.
