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, is manufactured to the exact tolerances required by the engine assembly, ensuring a drop-in fit with no guesswork at the workbench. This piston pin is confirmed compatible across a wide range of DPU variants including He, Heh, Hec, Hech, Heap, Hesh, Hecsh, and Hecs configurations, covering both standard and US-spec models. Keep a genuine Wacker Neuson replacement on hand to get your reversible plate compactor back to full compaction force as quickly as possible.
Key Features
- OEM-Grade Dimensional Accuracy — Manufactured to the exact bore diameter and surface finish spec of the original, maintaining correct wrist-pin-to-piston clearance for proper combustion dynamics.
- Direct Engine Drop-In — Engineered to seat into the piston and connecting rod exactly as the factory assembly, with no filing, shimming, or adaptation at installation.
- Broad DPU Series Coverage — Fits DPU4545, DPU5545, DPU6555, and DPU6055 reversible vibratory plate compactors across He, Heh, Hec, Hech, Heap, Hesh, and related sub-variants, including US-spec machines.
- Protects Piston and Cylinder Integrity — A worn or undersized piston pin causes lateral piston slap inside the cylinder bore, accelerating wear on the piston, rings, and cylinder wall — replacing it at the correct interval preserves the full engine assembly.
- Genuine Wacker Neuson OEM Part — Sourced directly from Wacker Neuson, part number 5000094862 carries the same quality assurance as the component originally installed at the factory.
The piston pin — also called a wrist pin — connects the piston to the small end of the connecting rod, transferring the force of combustion downward through the crankshaft to drive the machine. It must withstand extreme cyclic loading on every power stroke, so precise fit and material hardness are critical. When a piston pin wears or develops excessive play, it produces a knocking noise at idle, causes uneven piston travel, and can lead to accelerated wear or scoring of the cylinder wall — ultimately resulting in loss of compression and engine failure if left unaddressed.
