The Wacker Neuson Rocker Arm is a genuine OEM component designed for BS50-4As, BS60-4As, BS70-4As, BS62-4Ab/28, BS65-4As, BS68-4Ab/28, and BS72-4As series rammers. As a direct-from-manufacturer part, the is produced to the same specifications as the original, ensuring a drop-in fit with no guesswork at installation. Compatibility extends across a broad range of 4-stroke rammer variants including US, CN, and Sunbelt-spec machines, making this the correct choice whether you're servicing a single unit or maintaining a fleet. Keep your rammer running at full output by replacing a worn or damaged rocker arm with this verified OEM part.
Key Features
- OEM Valve Train Geometry: — Manufactured to exact Wacker Neuson tolerances, preserving the correct rocker arm ratio and contact surface profile critical to consistent valve actuation on 4-stroke rammer engines.
- Direct Drop-In Installation: — Engineered to seat on the original rocker shaft and align with the valve stem and pushrod without modification, saving time on the bench.
- Broad 4-Stroke Rammer Compatibility: — Fits BS50-4As, BS60-4As, BS65-4As, BS68-4As, BS70-4As, BS72-4As, and BS62-4A series rammers across standard, US, CN, and Sunbelt configurations.
- Restores Full Engine Breathing: — A correctly functioning rocker arm ensures valves open and close at the right lift and timing, maintaining compression and power output in demanding compaction work.
- Genuine Wacker Neuson Part: — Supplied as authentic OEM stock under part number 5100049252, so you're getting the same component that left the factory with the machine.
The rocker arm is a pivoting lever in the valve train of a 4-stroke engine, transferring motion from the camshaft-driven pushrod to open the intake and exhaust valves at the correct moment in the combustion cycle. In a rammer engine operating under continuous high-vibration loads, the rocker arm is subject to accelerated wear at its contact faces and pivot bore. When it wears or fails, valve lift drops, compression suffers, and the engine loses the power needed to drive the percussion mechanism — resulting in weak compaction force or a machine that won't run cleanly. Replacing a worn rocker arm promptly restores proper valve timing and brings engine performance back to specification.
