The Wacker Neuson is a genuine OEM Crankshaft Gear designed for the G40, G50, G60, G70, G95, and G110 series portable generators. As a factory-sourced component, it is manufactured to the exact tolerances required for proper valve timing and engine synchronization across this generator family. This part fits a wide range of G-series configurations including standard, mobile, and international 50Hz variants. Confirm your model number before ordering to ensure the correct application match.
Key Features
- Genuine OEM Tooth Profile Accuracy — Manufactured to exact gear tooth geometry specifications, ensuring correct mesh with the camshaft gear and maintaining precise engine timing.
- Broad G-Series Compatibility — Fits G40, G50, G60, G70, G95, and G110 generator models across multiple build configurations, including mobile and international 50Hz variants.
- Drop-In Engine Replacement — Engineered as a direct swap for the original crankshaft gear; installs in the same position with no machining or alteration to the engine block.
- Timing-Critical Component — A worn or damaged crankshaft gear causes valve timing drift, leading to rough running, misfires, or complete engine failure — correct replacement restores proper combustion cycles.
- Sourced Direct from Wacker Neuson — Supplied as a genuine OEM part, matching the original material hardness and tooth count used on the production line.
The crankshaft gear is a precision-machined component mounted on the crankshaft that drives the camshaft gear, controlling the opening and closing of the engine's valves in sync with piston movement. In a portable generator engine, maintaining accurate timing between the crankshaft and camshaft is essential for efficient combustion, stable power output, and long engine life. When the crankshaft gear wears, chips, or loses tooth integrity, timing accuracy degrades — symptoms typically include rough idling, loss of power output, excessive vibration, or the engine failing to start altogether.
