Wacker Neuson 5000202298 Percussion Piston

The Wacker Neuson Percussion Piston is a genuine OEM component designed for the BH 24, BH 24 Low Vib, BH 24 Low Vib RS, BH 55rw, BH 65, EH 25, EH 65, EH 70, and EH 75 series breakers. As a direct-from-manufacturer part, the meets Wacker Neuson's original design tolerances, ensuring the percussion mechanism operates exactly as intended. This part covers an extensive range of gasoline and electric breaker configurations across both hex and round shank variants. Cross-reference your model and serial number against the fitment list before ordering to confirm compatibility.

Key Features

• Genuine OEM Impact Tolerance — Manufactured to Wacker Neuson's original percussion specifications, this piston withstands the high-cycle impact loads that cause premature failure in substandard alternatives.
• Drop-In Replacement — The 5000202298 installs directly into the percussion housing with no reworking of bore dimensions or retainer clips, matching the original part's geometry precisely.
• Broad Breaker Series Coverage — Fits BH 24, BH 24 Low Vib, BH 24 Low Vib RS, BH 55rw, BH 65, EH 25, EH 65, EH 70, and EH 75 models across gasoline and electric variants, including US, European, and SEA market configurations.
• Restored Strike Energy — A correctly functioning percussion piston delivers consistent blow energy to the chisel. A worn or damaged piston causes reduced chipping force, erratic impact rhythm, and accelerated wear on surrounding components.
• Operational Safety Assurance — In a breaker, a failed percussion piston can cause uncontrolled recoil and unpredictable tool behavior. Using a genuine OEM replacement maintains the predictable, controlled striking action the machine was engineered to deliver.

The percussion piston is the core striking component inside a breaker's impact mechanism. When the engine or motor drives the piston forward, it strikes the chisel retainer with rapid, repeated force — that impact energy is what breaks up concrete, asphalt, and compacted material at the work face. When the piston wears, cracks, or loses its surface hardness, blow energy drops noticeably, the machine vibrates unevenly, and continued operation risks damaging the cylinder bore and surrounding seals. Replacing the percussion piston with a genuine Wacker Neuson part restores the machine to full striking performance and protects the integrity of the components around it.
