The Wacker Neuson Set of Piston Rings is a genuine OEM set of piston rings designed for the BS50-4As, BS60-4As, BS65-4As, BS70-4As, and BS72-4As series gasoline vibratory rammers. As a direct factory replacement, this set restores proper cylinder sealing and compression to keep your rammer delivering full compaction force in trench and cohesive soil applications. Wacker Neuson genuine OEM parts are manufactured to the same specifications as the originals, ensuring a drop-in fit with no guesswork. Keep a set on hand and you'll be back compacting with full power in minimal time.
Key Features
- Restored Cylinder Compression — Correctly sized rings reseal the piston-to-cylinder wall gap, recovering the compression loss that causes hard starting, weak impact force, and excessive fuel consumption in worn rammers.
- Genuine OEM Ring Geometry — Each ring is manufactured to the exact radial thickness, end-gap tolerance, and tension specification of the original, ensuring consistent seating against the cylinder bore without the need for hand-fitting.
- Broad BS-Series Rammer Compatibility — Fits multiple configurations of the BS50-4As, BS60-4As, BS65-4As, BS70-4As, and BS72-4As gasoline rammers, including US and CN market variants, covering a wide range of serial-number ranges.
- Complete Set for a Full Ring Service — Supplied as a matched set so compression rings and oil control rings are replaced together in a single service interval, eliminating the risk of mismatched wear between old and new rings.
- Engine Longevity After Rebuild — Fresh rings that seal correctly reduce blow-by, protect the cylinder wall from accelerated wear, and extend the service life of the surrounding piston and bore components.
- Fuel System Safety Compliance — Proper compression sealing prevents unburned fuel from washing past the rings into the crankcase oil, which can degrade lubrication and create a fire or emissions risk in the lower engine.
Piston rings form the dynamic seal between the piston and the cylinder wall inside the rammer's four-stroke gasoline engine. They perform two critical jobs: holding combustion pressure above the piston so the engine produces full power, and scraping excess oil off the cylinder wall to prevent it from burning in the combustion chamber. When rings wear, lose tension, or break, compression drops sharply — the rammer becomes difficult to start, delivers noticeably weaker blows, and may smoke or consume oil at an abnormal rate. Replacing the full set of piston rings at the correct service interval, or whenever these symptoms appear, is one of the most cost-effective ways to restore a rammer's impact performance and protect the engine from deeper mechanical damage.
