The Wacker Neuson Percussion Piston is a genuine OEM component designed for the BH 22, BH 23, BH 55, BH 65, EH 22, EH 23, and EH 24 series gasoline and electric breakers. As a direct OEM replacement, it is manufactured to the same specifications as the original part, ensuring a correct installation without modification. This piston is the core striking component inside the breaker mechanism, and using the correct part is critical to restoring full impact output. Confirm your model number before ordering — this part fits a wide range of BH and EH series breakers across multiple tool holder configurations.
Key Features
- Genuine OEM Impact Specification — Manufactured to the exact mass and hardness tolerances required for consistent percussive output in Wacker Neuson BH and EH series breakers.
- Drop-In Replacement for BH and EH Series — Fits directly into the percussion mechanism housing of compatible BH 22, BH 23, BH 55, BH 65, EH 22, EH 23, and EH 24 models with no alteration to the breaker body.
- Broad Model Coverage — A single part number covers BH 23 and BH 55 gasoline breakers across 27x80, 25x108, 28x152, and 28x160 tool holder variants, as well as BH 65 and the EH 22, EH 23, and EH 24 electric breaker families.
- Restores Full Strike Energy — A worn or damaged percussion piston causes a noticeable drop in blow frequency and impact force; replacing it with part 5000064624 returns the breaker to its rated breaking performance.
- Safety-Critical Striking Component — A cracked or fatigued piston can fracture under load, creating a hazard inside the breaker housing; always replace with a genuine OEM part rated for the breaker's operating pressure cycle.
The percussion piston is the reciprocating striking element at the heart of a breaker's impact mechanism. Driven by the engine or motor through the breaker's internal pneumatic or mechanical drive, it delivers rapid, high-force blows to the tool shank, which transfers that energy into the work surface. When the piston wears, chips, or loses dimensional accuracy, blow frequency drops, the tool shank receives uneven strikes, and the breaker may stall under load or fail to penetrate hard material altogether.
