The Wacker Neuson is a genuine OEM Piston Ring Oversize 0.50 designed for the VP1340R, VP1340RW, VP1550R, VP1550RW, VP2050R, VP2050RW, and AP1550R single-direction vibratory plate compactors. As an oversize component, this ring is engineered to restore proper cylinder-to-piston clearance during engine rebuild on machines where the cylinder bore has been honed or bored to the 0.50mm oversize specification. Sourced directly from Wacker Neuson, part number is manufactured to the same tolerances as the original engine component, ensuring correct ring gap, tension, and seal geometry for the application. Confirm your engine's bore size before ordering to ensure this oversize variant is the correct fit for your rebuild.
Key Features
- Oversize-Specific Ring Geometry — Dimensioned to the 0.50mm oversize bore specification, delivering the correct radial wall thickness and ring gap for a properly honed or bored cylinder.
- Genuine OEM Construction — Manufactured to Wacker Neuson's original tolerances for ring tension and seating surface finish, maintaining combustion seal integrity and oil control in the engine.
- Engine Rebuild Application — Drops into the oversize piston assembly during a full engine overhaul; intended for use alongside the matching oversize piston when the original bore has been reconditioned.
- Broad VP and AP Series Coverage — Compatible with VP1340R, VP1340RW, VP1550R, VP1550RW, VP2050R, VP2050RW, and AP1550R vibratory plate compactors across Wacker Neuson's single-direction plate lineup.
- Restored Compression and Oil Control — A correctly fitted oversize piston ring eliminates blow-by, restores compression pressure, and prevents oil burning that results from worn ring-to-bore clearances.
A piston ring seals the combustion chamber between the piston and the cylinder wall, maintaining compression pressure and preventing combustion gases from escaping into the crankcase. It also controls oil consumption by scraping excess oil from the cylinder wall on each downstroke. When rings are worn or damaged, compression drops, the engine loses power, burns oil, and may produce excessive smoke — symptoms that point to a needed engine overhaul. An oversize piston ring like the 5000158407 is specifically used when the cylinder bore has been machined beyond its standard diameter, restoring the tight seal required for full engine output on the vibratory plate compactor.
