The Wacker Neuson Valve Rocker Arm is a genuine OEM component designed for the BS50-4As, BS60-4As, and BS70-4As series vibratory rammers. As a direct-from-manufacturer part, it meets the exact material and dimensional standards specified for these machines, ensuring the valvetrain operates exactly as intended. This OEM designation means you're installing the same part that left the factory — no guesswork on fitment or specification. Compatible across multiple shoe configurations including the 280 mm and 11-inch plastic shoe GRX variants within the BS 4As rammer series.
Key Features
- Genuine OEM Valvetrain Geometry — Machined to the exact rocker ratio and contact surface profile specified by Wacker Neuson, preserving correct valve lift and timing.
- Drop-In Engine Replacement — Engineered to mount directly onto the existing rocker shaft and align with the valve stem and pushrod without modification to surrounding components.
- Broad BS 4As Series Coverage — A single part number covers BS50-4As, BS60-4As, and BS70-4As rammers across multiple shoe configurations, simplifying parts sourcing for mixed fleets.
- Sustained Engine Breathing Performance — A correctly functioning rocker arm ensures full, consistent valve actuation; a worn or damaged arm causes misfiring, loss of compression, and reduced compaction output.
- OEM Part Number Verified — Part number 5200015342 is the authorized Wacker Neuson reference, giving you a direct match when cross-referencing your machine's parts manual.
The valve rocker arm sits at the heart of the engine's valvetrain, transferring motion from the camshaft — via the pushrod — to open and close the intake and exhaust valves at precisely the right moment. On a vibratory rammer like the BS 4As series, where the engine runs under sustained mechanical load, consistent valve actuation is critical to maintaining proper combustion and full power output. When a rocker arm wears at its pivot point or contact surfaces, valve timing becomes erratic, leading to rough running, hard starting, and progressive loss of compaction force.
