Wacker Neuson 5000073682 Piston Rings Set, 3 Per

The Wacker Neuson is a genuine OEM Piston Rings Set, 3 Per, designed for a broad range of Wacker Neuson diesel-powered compaction equipment including the DS720 Diesel Vibratory Rammer, VPY1740 and VPY1750 Diesel Vibratory Plates, DPS1850Y Vibration Plate, DPU 2950Y Reversible Vibratory Plate, VP2050Y Value Vibratory Plate, and the D4000 Diesel Power Unit for Internal Vibrators. Sourced directly from Wacker Neuson, part number is manufactured to the same tolerances as the original rings fitted at the factory, ensuring correct sealing geometry and ring gap specification for these diesel engines. This set includes three rings to complete a full cylinder rebuild, covering compression and oil control rings as required by the engine design. Confirm your model number against the fitment list before ordering to ensure this set matches your specific machine configuration.

Key Features

• Genuine OEM Sealing Tolerances — Each ring is manufactured to the exact dimensional and tension specifications of the original Wacker Neuson engine build, maintaining correct compression and oil control for these diesel powerplants.
• Complete Three-Ring Set — Includes all three rings needed for a full cylinder overhaul, so you have everything required for a single-cylinder rebuild in one part number.
• Broad Diesel Compaction Fitment — Compatible with the DS720 Diesel Rammer, VPY1740, VPY1750, and DPS1850Y Vibratory Plates, DPU 2950Y Reversible Plate, VP2050Y Value Vibratory Plate, and D4000 Diesel Power Unit.
• Restores Full Compression Output — Worn or broken piston rings allow combustion gases to bypass the piston, causing hard starts, loss of power, and excessive oil consumption; a fresh set restores proper cylinder pressure and engine performance.
• Direct Engine Replacement — Rings are sized to drop into the original cylinder bore without modification, allowing a straightforward installation during a standard engine top-end service.

Piston rings seal the gap between the piston and the cylinder wall, performing two critical jobs: containing combustion pressure above the piston to generate power, and scraping excess oil back down the cylinder to prevent it from burning. In a diesel-powered compaction machine that operates under sustained high-vibration loads, rings wear over time, losing their seating tension and allowing blow-by — the escape of combustion gases past the piston. When this happens, the engine loses compression, starts poorly, burns oil, and may produce excessive exhaust smoke. Replacing the ring set with a correctly specified genuine OEM set restores the tight cylinder seal the engine needs to run at full power and efficiency.
