The Wacker Neuson is a genuine OEM Set of Piston Rings designed for RD7H series walk-behind tandem rollers and the DPU 4045H, DPU 4545H, DPU 5045H, and DPU 5545H series diesel reversible vibratory plate compactors. As a factory-sourced component, is manufactured to the exact tolerances required by the engine in these machines, ensuring a correct seal between the piston and cylinder wall. This set covers an extensive range of RD7H and DPU variants, making it the right choice for operators and dealers servicing Wacker Neuson's diesel-powered compaction lineup. Verify your machine's model and serial number against the fitment list before ordering to confirm this is the correct ring set for your application.
Key Features
- Genuine OEM Tolerancing — Manufactured to the exact radial width, thickness, and end-gap specifications of the original engine build, ensuring a consistent compression seal across all cylinder bores in the application range.
- Drop-In Engine Replacement — Engineered to seat correctly in the original piston ring grooves without machining or modification to the piston or bore, supporting a straightforward top-end rebuild.
- Broad Fitment Across Diesel Compaction Models — Confirmed fit for the RD7H tandem roller family and DPU 4045H, DPU 4545H, DPU 5045H, and DPU 5545H diesel reversible vibratory plate compactors, including electric-start, canopy, and export variants.
- Compression and Oil Control Restored — A fresh set of piston rings eliminates blow-by, restores lost compression, and controls oil consumption — returning the engine to full power output and efficient fuel burn.
- Critical Fuel System Safety — Worn piston rings on diesel compaction equipment can cause excessive crankcase pressure and oil contamination of the fuel system; replacing them on schedule prevents progressive internal engine damage.
Piston rings form the dynamic seal between each piston and the cylinder wall inside the engine. They perform two jobs simultaneously: holding combustion pressure above the piston so the engine generates full power, and scraping excess oil back down the bore so it doesn't burn off in the combustion chamber. When rings wear, gap, or break, combustion gases escape past the piston — a condition called blow-by — which reduces power, increases fuel consumption, and forces contaminated gases into the crankcase. Left unaddressed, worn rings accelerate bore wear and can lead to a full engine failure, making timely ring replacement one of the most cost-effective engine rebuilds available for diesel-powered compaction equipment.
