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 replacement sourced through authorized Wacker Neuson supply channels, part number is manufactured to the exact material and dimensional tolerances required by the engine assembly. This pin fits an extensive range of DPU variants — including He, Heh, Hec, Hech, Heap, Hesh, Hecsh, and US-specification models — making it a go-to engine rebuild component for technicians servicing multiple units across a fleet. Confirm your model number before ordering to ensure a correct match.
Key Features
- OEM-Grade Material Hardness — Manufactured to the exact case-hardening and surface-finish specifications required for piston-to-connecting-rod loads in DPU-series diesel engines, ensuring the pin withstands sustained compaction cycle stress.
- Drop-In Engine Fit — Machined to OEM bore and outside diameter tolerances so the pin seats correctly in both the piston bosses and the small-end bearing without clearance adjustment.
- Broad DPU Series Coverage — A single part number covers DPU4545, DPU5545, DPU6555, and DPU6055 plate compactors across He, Heh, Hec, Hech, Heap, Hesh, Hecsh, and US-specification variants.
- Engine Longevity at Stake — A worn or undersized piston pin allows lateral play that accelerates piston and cylinder wall wear; replacing it on schedule preserves compression and keeps the exciter-drive engine producing rated output.
- Genuine Wacker Neuson OEM Part — Supplied as an authorized OEM component, part number 5000094862 carries the correct Wacker Neuson part traceability for service records and warranty documentation.
The piston pin — also called a wrist pin or gudgeon pin — connects the piston to the small end of the connecting rod inside the engine cylinder. It acts as the pivot point that transfers the linear force of combustion into rotational movement at the crankshaft. On DPU-series reversible vibratory plate compactors, this translates directly into the eccentric shaft rotation that generates compaction force at the baseplate. When a piston pin wears, becomes scored, or develops excessive clearance, it creates audible knocking, increased oil consumption, and a loss of engine power — all of which reduce the compaction output the machine delivers on site.
