The Wacker Neuson Exhaust Valve is a genuine OEM exhaust valve designed for the BS50-4As, BS60-4As, BS65-4As, BS70-4As, BS72-4As, BS62-4Ab/28, BS68-4Ab/28, and related 4-stroke rammer series. Sourced directly from Wacker Neuson, this part meets the same specifications as the component originally installed at the factory. It is a direct-fit replacement for a wide range of BS-series rammer models, including US, CN, and standard variants, as well as Sunbelt-designated configurations.
Key Features
- Genuine OEM Valve Integrity — Manufactured to Wacker Neuson's original sealing and heat-tolerance specifications, ensuring the exhaust valve seats and seals correctly under the high-temperature cycling demands of a 4-stroke rammer engine.
- Direct-Fit Installation — Engineered to match the original valve dimensions and seat profile, so it drops into the cylinder head without machining or adaptation.
- Broad BS-Series Compatibility — Confirmed fitment across BS50-4As, BS60-4As, BS65-4As, BS70-4As, BS72-4As, BS62-4Ab/28, and BS68-4Ab/28 rammer models, including US, CN, and Sunbelt variants.
- Sustained Engine Compression — A properly seating exhaust valve maintains combustion chamber pressure, keeping the engine running at full power output and preventing the rough running or hard-starting caused by a worn or burnt valve.
- Emissions and Engine Safety Compliance — A correctly functioning exhaust valve is critical to proper combustion and exhaust gas management; using a genuine OEM part ensures the engine operates within its designed emissions and temperature parameters.
The exhaust valve controls the release of burned combustion gases from the engine cylinder on each exhaust stroke. It opens at precisely the right moment in the engine cycle to vent exhaust, then closes to seal the combustion chamber for the next compression and power stroke. When an exhaust valve wears, burns, or fails to seal correctly, compression drops, power output falls, fuel consumption rises, and the engine can develop a persistent misfire or become difficult to start. Replacing a damaged exhaust valve promptly restores full compression and protects the surrounding valve seat and cylinder head from further damage.
