The Wacker Neuson is a genuine OEM Exhaust Rocker Arm designed for the DS70 and DS720 diesel vibratory rammer series. Sourced directly from Wacker Neuson, this part matches the exact geometry and material specification of the original component installed at the factory. Fitment covers multiple DS70 and DS720 configurations, including EPA-compliant 280mm and 330mm shoe variants. Keeping the valve train in proper working order is critical to consistent rammer performance — the ensures the exhaust valve opens and closes at precisely the right moment every stroke.
Key Features
- OEM Valve Train Geometry: — Cast and machined to the same rocker arm profile as the original, maintaining correct valve lift and timing across the exhaust cycle.
- Direct Drop-In Replacement: — Mounts to the existing rocker shaft and retains all stock hardware connections without rework or shimming.
- Broad DS-Series Fitment: — Confirmed compatible with DS70 and DS720 diesel rammers in 280mm/11in and 330mm/13in shoe configurations, including EPA-rated models.
- Protects Engine Longevity: — A worn or cracked exhaust rocker arm causes erratic valve actuation, leading to loss of compression, hard starting, and accelerated cylinder wear.
- Fuel System Safety Consideration: — Correct rocker arm function prevents exhaust valve float at operating RPM, which can cause backfiring and uncontrolled fuel ignition in the combustion chamber.
The exhaust rocker arm is a pivoting lever in the engine's valve train that transfers motion from the camshaft to the exhaust valve, pushing it open at the correct point in the combustion cycle to release spent gases from the cylinder. On diesel rammers like the DS70 and DS720 — which operate under sustained high-load, high-vibration conditions — the rocker arm is subject to constant mechanical stress and wear at the contact pad and pivot bore. When the exhaust rocker arm wears or fails, the exhaust valve can no longer open fully or at the right time, resulting in lost power, rough running, overheating, and eventual engine damage if left unaddressed.
