The Wacker Neuson is a genuine OEM Rocker Arm designed for the BS50-4s, BS60-4s, BS50-4, and BS60-4 series gasoline vibratory rammers. As a factory-original component, it is manufactured to the same specifications as the part it replaces, ensuring correct valve train geometry and consistent engine performance. This part covers an extensive range of BS-series rammer configurations, including standard, EU, and high-altitude variants, making it a widely applicable engine component across the Wacker Neuson jumping jack rammer lineup. Always verify your machine number against the fitment list before ordering to confirm compatibility.
Key Features
- Genuine OEM Valve Train Accuracy — Factory-original rocker arm maintains correct valve-to-rocker contact geometry, preserving proper valve lift and timing across the engine's service life.
- Direct-Fit Replacement — Engineered to match the original pivot bore dimensions and arm profile, allowing the rocker arm to seat correctly on the rocker shaft without adjustment.
- Broad BS-Series Coverage — Compatible with BS50-4s, BS60-4s, BS50-4, and BS60-4 vibratory rammers across standard, EU, and high-altitude configurations, covering a wide range of machine numbers in the Wacker Neuson rammer family.
- Protects Valve and Camshaft Wear — A correctly fitted rocker arm distributes load evenly across the valve stem tip and pushrod, preventing accelerated wear on adjacent engine components.
- Fuel System Interaction Note — Improper valve actuation caused by a worn or damaged rocker arm can lead to hard starting, rough running, and reduced compaction output — replacing this part restores proper combustion cycle timing.
The rocker arm is a pivoting lever in the engine's valve train that transfers motion from the camshaft — via the pushrod — to open and close the intake and exhaust valves. In a four-stroke rammer engine like those found in the BS50-4s and BS60-4s, precise rocker arm function is essential for correct valve timing, efficient combustion, and consistent power delivery to the rammer mechanism. When a rocker arm wears at its contact surfaces or becomes damaged, valve actuation becomes erratic, leading to loss of compression, difficult starting, and reduced impact force at the shoe.
