The Wacker Neuson Piston Pin is a genuine OEM component designed for the DPU4545, DPU5545, DPU6055, and DPU6555 series reversible vibratory plate compactors. As a direct OEM replacement, part is manufactured to the same tolerances as the original, ensuring correct installation into the engine's reciprocating assembly without modification. This piston pin covers an extensive range of DPU variants — including He, Heh, Hec, Hech, Heap, and Hesh configurations — making it a versatile keep-on-hand component for fleets running multiple DPU models. Confirm your model number before ordering to ensure this is the correct pin for your specific machine configuration.
Key Features
- OEM-Grade Dimensional Accuracy — Manufactured to the exact diameter and surface finish tolerances required for correct wrist-pin fit in the connecting rod and piston bore, preventing slop or binding in the reciprocating assembly.
- Drop-In Engine Replacement — Engineered to install directly into the piston and connecting rod of the original engine assembly, aligning with existing circlip grooves and bearing surfaces.
- Broad DPU Series Compatibility — Fits DPU4545, DPU5545, DPU6055, and DPU6555 reversible vibratory plate compactors across He, Heh, Hec, Hech, Heap, Hesh, and related variant suffixes.
- Sustained Compression and Power Output — A correctly fitted piston pin maintains proper piston geometry and combustion alignment, supporting the full compaction force output these heavy-duty DPU plates are built to deliver. A worn or seized pin causes power loss, increased vibration, and accelerated engine wear.
- Genuine Wacker Neuson OEM Part — Sourced directly through the Wacker Neuson parts network, carrying the same part number 5000094862 used by authorized service centers worldwide.
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. It transfers combustion forces from the piston into the rotating crankshaft assembly, making it a critical link in the engine's power delivery chain. When a piston pin wears, becomes loose, or seizes, the result is typically a characteristic knocking noise, loss of power, and — if left unaddressed — catastrophic engine damage that goes well beyond a simple pin replacement.
