The Wacker Neuson Piston Rings Set is a genuine OEM component designed for the DPU4545, DPU5545, DPU6055, and DPU6555 series reversible vibratory plate compactors. Sourced directly from Wacker Neuson, this Piston Rings Set is manufactured to the exact tolerances required by the engine in these heavy-duty diesel-powered compactors. The covers an extensive range of DPU variants — including He, Heh, Hec, Heap, and Hech configurations — making it the correct service part for a wide cross-section of the DPU lineup. Verify your model number before ordering to confirm fitment.
Key Features
- OEM-Spec Ring Tolerancing — Manufactured to exact bore diameter and ring gap specifications for the engines used across the DPU4545, DPU5545, DPU6055, and DPU6555 series, ensuring proper compression seal from the first start-up after installation.
- Drop-In Engine Fit — Engineered to seat correctly in the piston ring grooves of the OEM piston without machining or modification to cylinder bore preparation beyond standard honing practice.
- Broad DPU Series Coverage — A single part number, 5000217086, services multiple DPU model variants across the 4545, 5545, 6055, and 6555 families, including He, Heh, Hec, Heap, Hech, and Hesh configurations.
- Compression Integrity Restored — Worn or broken piston rings allow combustion gases to bypass the piston, causing loss of power, excessive oil consumption, and hard starting. A fresh set restores full cylinder compression and engine output.
- Critical Fuel System Safety — Proper ring seal prevents blow-by gases from contaminating the crankcase oil, protecting bearings and internal engine components from accelerated wear on machines running under high compaction loads.
Piston rings form the dynamic seal between the piston and the cylinder wall, containing combustion pressure and controlling oil consumption inside a diesel engine. There are typically multiple rings per piston — compression rings that hold combustion gases above the piston, and an oil control ring that regulates lubrication film on the cylinder wall. When piston rings wear, crack, or lose tension, compression drops, the engine burns oil, produces blue exhaust smoke, and struggles to develop the power needed to drive the compaction mechanism effectively. Replacing a worn Piston Rings Set is one of the most fundamental engine rebuilds, restoring compression, fuel efficiency, and overall engine longevity in the DPU compactor.
