Key Features
- Genuine OEM Valve Train Geometry — Manufactured to the original pivot ratio and contact surface profile, ensuring correct valve lift and timing are maintained in the 4-stroke engine.
- Direct Drop-In Replacement — Designed to seat onto the existing rocker shaft and engage the valve stem and pushrod without any modification to the cylinder head assembly.
- Broad BS-Series Compatibility — Fits BS50-4As, BS60-4As, BS65-4As, BS68-4As, BS70-4As, BS72-4As, and BS62-4Ab/28 rammers across US, CN, and standard market variants.
- Restores Engine Breathing Efficiency — A worn or worn rocker arm causes inconsistent valve actuation, leading to rough running, power loss, and hard starting — replacing it with this OEM part restores proper combustion cycle performance.
- OEM Part Number Verified — Listed under Wacker Neuson part number 5100049253, cross-referenced across multiple BS-series machine configurations for accurate identification.
The rocker arm is a pivoting lever in the engine's valve train that transfers motion from the pushrod to open and close the intake and exhaust valves in time with the piston. In a 4-stroke rammer engine like those in the BS series, precise rocker arm function is critical — if the arm is worn, cracked, or has a damaged contact surface, valve timing becomes erratic, robbing the engine of compression and causing rough or failed starts. Replacing a worn rocker arm promptly keeps the engine running at its correct power output and prevents secondary damage to the valve stems and seats.
