The Wacker Neuson Piston Pin is a genuine OEM component designed for the BH 22, BH 23, BH 55, and BH 65 gasoline breaker series, as well as the EH 22, EH 23, EH 27, and EH 50 electric breaker series. Sourced directly through the Wacker Neuson OEM supply chain, this Piston Pin meets the original design and material specifications required by these breaker families. Fitment covers a wide range of BH and EH configurations across multiple tool holder sizes, including 27x80, 25x108, 28x152, and 28x160 variants. If your machine is due for a percussion mechanism service, part number is the correct OEM replacement to restore full striking performance.
Key Features
- OEM-Grade Material Hardness — Manufactured to the exact hardness and surface finish specification required for the high-cycle impact loads inside BH and EH series breaker mechanisms.
- Drop-In Replacement for BH and EH Breakers — Installs directly into the piston bore without modification, maintaining correct pin-to-bore clearance for proper percussion function.
- Broad Breaker Family Coverage — Compatible with the BH 22, BH 23, BH 55, and BH 65 gasoline breakers and the EH 22, EH 23, EH 27, and EH 50 electric breakers across multiple tool holder configurations.
- Sustained Impact Energy Output — A correctly fitted Piston Pin ensures consistent energy transfer through the percussion cycle; a worn or undersized pin causes loss of blow energy, increased vibration, and accelerated wear on surrounding components.
- Percussion System Integrity — In a reciprocating breaker mechanism, pin wear directly affects striker alignment; using the correct OEM pin prevents off-axis loading that can damage the cylinder and piston assembly.
The Piston Pin is a core component of a demolition breaker's percussion mechanism. It connects the piston to the striker or drive linkage, transmitting the reciprocating force that delivers each blow to the tool. Because it operates under continuous high-frequency impact loading, the pin must maintain tight dimensional tolerances — even minor wear leads to play in the mechanism, reduced blow energy at the chisel, and rapid deterioration of the surrounding bore and piston. Replacing a worn Piston Pin with the correct OEM part restores the full striking efficiency of the breaker and protects the more costly components around it.
