The Wacker Neuson Piston Rings Set is a genuine OEM component designed for RD7 series walk-behind tandem rollers and the DPU 4045H, DPU 5045H, DPU 4545H, and DPU 5545H reversible vibratory plate compactors. As a direct OEM replacement, part is manufactured to the exact tolerances required by these diesel-powered machines, ensuring proper sealing and combustion performance. This set covers a wide range of RD7 and DPU variants — including He, Heh, Hec, and Heap configurations — making it a versatile service part for fleets running multiple Wacker Neuson diesel compaction machines. Confirm your model number before ordering to ensure this set matches your specific engine configuration.
Key Features
- OEM-Spec Ring Tolerancing — Manufactured to exact bore diameter and groove depth specifications, ensuring a proper combustion seal and correct compression across all covered engine variants.
- Complete Set for Full Overhaul — Includes all rings required for a piston service, so technicians have everything needed for a thorough engine rebuild in a single part number.
- Broad Fitment Across Diesel Compaction Lines — Fits RD7 series walk-behind tandem rollers (including RD7H, RD7He, and RD7Heh variants) as well as DPU 4045H, DPU 5045H, DPU 4545H, and DPU 5545H reversible vibratory plate compactors.
- Restores Full Engine Compression — Worn or broken piston rings allow blow-by, rob the engine of power, and cause oil consumption. A fresh set restores compression so the machine delivers full compaction force.
- Genuine Wacker Neuson OEM Part — Sourced directly from Wacker Neuson, this set meets the same production standards as the rings installed at the factory, supporting correct engine operation over the long service life of the machine.
Piston rings seal the combustion chamber between the piston and the cylinder wall, maintaining the compression needed for the engine to fire reliably and generate full power. They also control oil consumption by preventing engine oil from entering the combustion chamber. When piston rings wear or break, compression drops, the engine loses pulling power, oil burns off faster than it should, and exhaust smoke increases — all signs that a ring replacement is overdue. Installing a fresh Piston Rings Set restores the tight seal the engine depends on, bringing combustion efficiency and oil control back to proper working order.
