The Wacker Neuson Rocker Arm is a genuine OEM component designed for the G40, G50, G60, G70, G95, and G110 portable generator series. Sourced directly from Wacker Neuson, this part meets the exact specifications of the original rocker arm installed at the factory. It is confirmed compatible across a wide range of G-series generator configurations, including standard, mobile, 50Hz LATAM, and Brazil market variants. When your generator's valve train needs attention, the is the correct OEM part to restore proper engine performance.
Key Features
- Genuine OEM Valve Train Precision — Manufactured to Wacker Neuson's exact geometry and hardness specifications, ensuring correct valve actuation timing and consistent contact with the valve stem and pushrod.
- Direct Drop-In Replacement — Engineered to the same pivot point dimensions and rocker ratio as the original, allowing straightforward installation without adjustment to the rocker shaft or head assembly.
- Broad G-Series Compatibility — Fits G40, G50, G60, G70, G95, and G110 generator models across standard, mobile, 50Hz LATAM, and Brazil Premium and Value configurations.
- Sustained Engine Efficiency — A correctly functioning rocker arm maintains proper valve lift and timing, supporting full power output and fuel efficiency in your generator under load.
- Protects Against Valve Train Damage — A worn or cracked rocker arm can cause erratic valve operation, misfires, or contact damage to the valve stem — replacing it promptly prevents more costly cylinder head repairs.
The rocker arm is a pivoting lever located in the engine's valve train, responsible for transferring motion from the camshaft (via the pushrod) to open and close the intake and exhaust valves. Precise and consistent valve actuation is essential for the engine to draw in the correct air-fuel mixture and expel exhaust gases at the right intervals, directly affecting power output and fuel economy. When a rocker arm wears at its contact surfaces, cracks, or loses its pivot clearance, valve timing becomes erratic — leading to rough running, loss of power, or difficulty starting the generator.
