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 dimensional tolerances required by the engine assembly, ensuring correct fit within the piston and connecting rod without rework. This pin is confirmed to fit an extensive range of DPU model variants across multiple configurations, including He, Heh, Hec, Hech, Heap, Hesh, and Hecs suffix builds. Sourcing the correct OEM piston pin protects the integrity of your engine rebuild and keeps your compactor operating at rated output.
Key Features
- OEM-Grade Dimensional Accuracy — Manufactured to exact bore and diameter tolerances for a flush, rattle-free fit between the piston and connecting rod in DPU-series Honda engines.
- Drop-In Engine Rebuild Component — Replaces the original pin during piston or connecting rod service; installs directly without machining or re-sizing.
- Broad DPU Series Coverage — Fits DPU4545, DPU5545, DPU6555, and DPU6055 reversible vibratory plate compactors across He, Heh, Hec, Hech, Heap, Hesh, Hecs, and related suffix variants.
- Protects Engine Longevity — A correctly sized piston pin maintains proper piston articulation and prevents side-loading on the cylinder wall; a worn or undersized pin accelerates bore wear and causes loss of compression.
- Genuine Wacker Neuson OEM Part — Sourced directly from Wacker Neuson, part number 5000094862 meets the same material and hardness specifications as the pin installed at the factory.
The piston pin — also called a wrist pin — is the precision cylindrical shaft that connects the piston to the small end of the connecting rod inside the engine. It allows the connecting rod to pivot as the crankshaft rotates, transferring combustion force into usable power. When a piston pin wears, becomes scored, or develops excessive clearance, it creates a characteristic knocking noise, causes uneven piston motion, and leads to accelerated wear on both the piston bosses and the connecting rod bore — ultimately compromising engine compression and output power.
