The Wacker Neuson Piston Pin is a genuine OEM component designed for the BPS1550B, BPS1550Bw, BPS2050B, BPS2050Bw, and A5000/160B series machines. As a factory-sourced part, it is manufactured to the exact tolerances required for proper piston and connecting rod alignment within the engine assembly. This pin is a direct drop-in replacement that restores the engine to its original operating condition without the need for any machining or fitting adjustments. If you're servicing one of these models, verifying part number against your machine's serial number ensures you're installing the correct component.
Key Features
- OEM-Spec Dimensional Accuracy — Manufactured to the precise diameter and hardness tolerances required for correct piston-to-rod engagement, preventing side play and uneven wear.
- Direct Engine Fit — Designed to install straight into the piston bore and connecting rod of compatible Wacker Neuson engines with no modification or custom fitting.
- Broad Model Compatibility — Confirmed fitment across the BPS1550B, BPS1550Bw, BPS2050B, BPS2050Bw, and A5000/160B series, covering multiple variants within these model families.
- Engine Integrity Restored — A worn or undersized piston pin causes piston rock, increased blow-by, and accelerated cylinder wall wear; replacing it with a correctly sized OEM pin restores compression and engine efficiency.
- Genuine Wacker Neuson Part — Sourced directly from Wacker Neuson, this is the same component used in original equipment assembly — not a substitute or approximation.
The piston pin — sometimes called a wrist pin — connects the piston to the small end of the connecting rod, allowing the rod to pivot as the piston moves up and down in the cylinder bore. It transfers combustion force directly from the piston into rotational motion at the crankshaft, making it one of the highest-stress components in the engine. When a piston pin wears, becomes loose, or develops surface damage, it causes a knocking noise, loss of power, and rapid deterioration of the surrounding piston and cylinder components — making timely replacement essential to preserving engine life.
