The Wacker Neuson Piston Pin is a genuine OEM component designed for the DPU4545, DPU5545, DPU6555, and DPU6055 series reversible vibratory plate compactors. As a factory-sourced part, it is manufactured to the exact dimensional and material tolerances required by the original engine assembly, ensuring a correct fit within the piston and connecting rod bore. Fitment spans an extensive range of DPU configurations including He, Heh, Hec, Hech, Heap, Hesh, and Hecsh variants, as well as select RD10 tandem roller applications. If you're sourcing by part number, is the confirmed OEM reference for this pin across all listed models.
Key Features
- OEM-Spec Dimensional Accuracy — Manufactured to exact bore diameter and surface hardness tolerances required for proper piston-to-rod articulation in Wacker Neuson DPU engines.
- Drop-In Engine Fit — Designed to seat directly into the piston bore and connect to the connecting rod without machining or rework, maintaining correct pin-to-bore clearance.
- Broad DPU Series Coverage — Confirmed fitment across DPU4545, DPU5545, DPU6555, and DPU6055 model families in multiple configuration variants (He, Heh, Hec, Hech, Heap, and more), plus select RD10 applications.
- Protects Engine Integrity — A worn or improperly sized piston pin causes piston slap, accelerated bore wear, and loss of compression — replacing it with the correct OEM part restores proper power output and smooth engine operation.
- Genuine Wacker Neuson OEM Part — Sourced directly through the Wacker Neuson parts network, carrying the full confidence of factory engineering and quality control behind every component.
The piston pin — also called a wrist pin — connects the piston to the small end of the connecting rod inside the engine, allowing the rod to pivot as the piston travels up and down in the cylinder bore. It transfers combustion force from the piston directly into rotational motion at the crankshaft, making it a critical load-bearing component in the engine's reciprocating assembly. When a piston pin wears, develops play, or seizes within its bore, it introduces knocking, vibration, and uneven power delivery — and if left unaddressed, can cause rapid and extensive internal engine damage.
