The Wacker Neuson is a genuine OEM Locking Device Complete designed for the EHB 7 and EH 6 series electric demolition breakers. Sourced directly from Wacker Neuson, this part meets the exact specifications of the original component installed at the factory. It is confirmed compatible with the EHB 7 M/230, EHB 7 M/115, EHB 7 M/120, EH 6 M/230, EH 6 M/115, and EH 6 M/120 models. Ordering by part number ensures you receive the correct assembly for your machine without guesswork.
Key Features
- Genuine OEM Retention Integrity — Manufactured to Wacker Neuson's original locking tolerances, ensuring the device engages and releases the chisel or tool bit with the correct retention force every time.
- Complete Assembly, Ready to Install — Supplied as a full Locking Device Complete unit, so all locking components are pre-matched and install as a single drop-in replacement.
- Broad EH / EHB Series Coverage — Fits EHB 7 M/230, EHB 7 M/115, EHB 7 M/120, EH 6 M/230, EH 6 M/115, and EH 6 M/120 electric breakers across both 115 V, 120 V, and 230 V voltage variants.
- Consistent Tool-Bit Retention — A fully functioning locking device holds the chisel securely during impact cycles, preventing tool-bit walkout and maintaining full energy transfer to the work surface.
- Operator Safety — A worn or failed locking device can allow the chisel to eject unexpectedly during operation. Replacing with a correct OEM unit restores secure retention and eliminates that hazard.
The locking device on an electric breaker is the mechanism that retains the chisel or tool bit in the chuck during demolition work. It holds the bit firmly in place while still allowing it to reciprocate freely under the hammer's impact force — a balance that is critical to both performance and safety. When the locking device wears or breaks, the tool bit can become loose, rattle in the chuck, or eject entirely, reducing breaking efficiency and creating a serious safety risk for the operator. Replacing the assembly complete, as part number 5000222555 provides, restores the correct retention geometry and spring tension required for safe, efficient operation.
