The Wacker Neuson Exhaust Rocker Arm is a genuine OEM component designed for BS50-4As, BS60-4As, and MS64A series vibratory rammers. Sourced directly from Wacker Neuson, this part matches the original specification exactly, ensuring a correct, hassle-free installation without any guesswork. It is confirmed to fit a wide range of BS50-4As and BS60-4As configurations, including standard, plastic shoe, high altitude, and hour meter variants, as well as the MS64A rammer. Keeping the valve train operating correctly is critical to engine performance, and the delivers the dependability you need to get your machine back to work.
Key Features
- OEM Valve Train Geometry: — Manufactured to the original pivot and contact dimensions, maintaining correct valve lift and timing across the exhaust cycle.
- Direct Drop-In Replacement: — Engineered to swap in on the same pivot shaft and valve stem as the original, with no fitting adjustments needed.
- Broad Rammer Compatibility: — Fits BS50-4As, BS60-4As, and MS64A vibratory rammer series, covering standard, plastic shoe, high altitude, and hour meter models.
- Protects Engine Breathing Performance: — A worn or damaged exhaust rocker arm causes poor valve actuation, leading to reduced power output, rough running, and accelerated engine wear.
- Genuine Wacker Neuson Part: — Carrying OEM part number 5200018720, this is an authorized Wacker Neuson component — not an imitation — so you know the material grade and wear characteristics match what left the factory.
The exhaust rocker arm is a pivoting lever in the engine's valve train that transfers motion from the camshaft to open the exhaust valve, allowing spent combustion gases to escape the cylinder. Without precise, consistent actuation from the rocker arm, exhaust valve timing suffers, robbing the engine of power and causing it to run hot or unevenly. When a rocker arm wears, cracks, or loses its contact surface, the symptoms show up quickly as rough idle, loss of compaction force, and hard starting — making timely replacement essential to keeping a rammer productive on site.
