The Wacker Neuson Inlet Rocker Arm is a genuine OEM component designed for the BS50-4As, BS60-4As, and MS64A vibratory rammer series. Sourced directly from Wacker Neuson, this part meets the exact tolerances required to keep the engine valve train operating as intended. It is a direct-fit replacement for all listed BS50-4As, BS60-4As, and MS64A model configurations, including standard, high-altitude, and plastic shoe variants. Confirm your model number against the fitment list before ordering to ensure correct application.
Key Features
- Genuine OEM Valve Train Tolerancing — Manufactured to Wacker Neuson's exact pivot geometry and surface hardness specifications, ensuring consistent rocker-to-valve contact without accelerated lobe wear.
- Drop-In Engine Valve Train Fit — Designed to seat directly onto the rocker shaft and engage the inlet valve stem with no reworking of the cylinder head or related hardware.
- Broad Rammer Series Coverage — Fits multiple BS50-4As, BS60-4As, and MS64A configurations, including standard, plastic shoe, hour meter, high-altitude, and US-market variants.
- Restored Intake Valve Timing — A correctly functioning inlet rocker arm opens the intake valve at precisely the right moment in the combustion cycle, maintaining full engine power output and fuel efficiency in demanding compaction work.
- Verified Wacker Neuson Part Number — Part number 5200018719 cross-references directly to Wacker Neuson's own parts catalog, giving you confidence you are installing the correct component the first time.
The inlet rocker arm is a pivoting lever inside the engine's valve train that transfers motion from the camshaft to the intake valve, opening it at precisely the right moment to allow the air-fuel mixture into the combustion chamber. On a vibratory rammer like the BS50-4As and BS60-4As, the engine works under constant load and vibration, placing steady stress on rocker arm pivot surfaces. When the inlet rocker arm wears or fails, the intake valve can no longer open fully or at the correct timing, resulting in loss of power, rough running, hard starting, or complete engine failure.
