The Wacker Neuson Piston +0.5 is a genuine OEM oversize piston designed for the DPU6555Heh and DPU6555Hech vibratory plate compactors. Sourced directly from Wacker Neuson, this part carries the same OEM specification as the original engine component, ensuring the correct bore clearance and dimensional tolerances for a proper rebuild. It is confirmed to fit the DPU6555Heh US, DPU6555Hech US, and DPU6555Hehapn vibration plate models. When you need an oversize piston that restores the engine to correct compression, the is the part to specify.
Key Features
- OEM Oversize Dimensional Accuracy — Machined to Wacker Neuson's +0.5mm oversize specification, ensuring correct bore-to-piston clearance after cylinder reconditioning.
- Genuine Wacker Neuson Component — Supplied as an authentic OEM part, carrying the same material grade and geometry as the original piston installed at the factory.
- Direct Engine Rebuild Fit — Engineered to drop into a correctly honed +0.5mm oversize bore on compatible DPU6555 series engines with no additional machining beyond standard cylinder prep.
- Confirmed Fitment for DPU6555 Series Plates — Compatible with DPU6555Heh US, DPU6555Hech US, and DPU6555Hehapn vibration plate models.
- Restores Full Compression — A correctly sized piston seals against the cylinder wall to recover lost compression, bringing engine output and compaction performance back to specification.
- Engine Longevity After Overhaul — Using the correct oversize piston during a rebuild prevents premature wear caused by excessive bore clearance, extending the service life of the reconditioned engine.
The piston is a core reciprocating component inside the engine cylinder, converting the force of combustion into the crankshaft rotation that drives the compactor's vibration system. As the piston moves through its stroke, it must maintain a precise fit against the cylinder wall — too much clearance results in blow-by, lost compression, increased oil consumption, and a noticeable drop in machine power. An oversize piston like the 5100062280 is used specifically when the cylinder bore has been honed out to compensate for wear, restoring that critical fit and bringing engine performance back in line with original output levels.
