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 direct OEM part, it is manufactured to the exact dimensional and material specifications required by the engine assembly, ensuring a correct installation with no guesswork on sizing or fit. Compatibility spans a wide range of DPU variants including He, Heh, Hech, Heap, Hes, Hesh, and related configurations across both standard and US-market machines. Keep part number on hand as a planned service item whenever piston or connecting rod service is performed on these heavy-duty diesel plate compactors.
Key Features
- OEM-Spec Dimensional Accuracy — Manufactured to the exact diameter and surface-finish tolerances required for correct piston-to-rod clearance in the DPU engine assembly, preventing premature wear on mating components.
- Direct Engine Drop-In — Sized and finished to seat directly into the piston bore and connecting rod small-end without machining or adjustment, supporting straightforward engine reassembly.
- Broad DPU Series Coverage — Fits DPU4545, DPU5545, DPU6555, and DPU6055 reversible vibratory plate compactors across He, Heh, Hech, Heap, Hes, Hesh, and US-market variants.
- Sustained Power Transfer — A correctly fitted piston pin maintains the rigid mechanical link between the piston and connecting rod, preserving full compression and consistent engine output for high-force compaction cycles.
- Genuine Wacker Neuson OEM Part — Sourced directly from Wacker Neuson, carrying the same part number (5000094862) used in original production, so you can confirm fitment against your machine's parts diagram with confidence.
The piston pin — also called a wrist pin or gudgeon pin — is the precision-hardened cylindrical shaft that connects the piston to the small end of the connecting rod inside the engine cylinder. It forms the pivot point that converts the connecting rod's angular motion into the piston's straight up-and-down stroke, transmitting combustion forces directly through the powertrain. When a piston pin wears, scores, or develops excessive clearance, it causes audible knocking, loss of compression, and accelerated wear to the piston, rod, and cylinder bore — eventually leading to internal engine failure if left unaddressed.
