The Wacker Neuson Camshaft Gear is a genuine OEM component designed for the G40, G50, G60, and G70 portable generator series. Sourced directly from Wacker Neuson, this part meets the exact dimensional and material specifications required for correct valve timing and engine synchronization. It is a confirmed fit across multiple G-series configurations, including standard, mobile, and premium variants produced for North American and Latin American markets. If your generator is showing signs of timing irregularities or the camshaft gear is worn or damaged, replacing it with part number ensures you restore the engine to its original operating specification.
Key Features
- Genuine OEM Gear Geometry — Machined to the exact tooth profile and pitch required for correct mesh with the crankshaft gear, maintaining accurate valve-to-piston timing.
- Direct Drop-In Replacement — Engineered to the original shaft bore and keyway dimensions of the G-series engine, so installation follows the standard service procedure without modification.
- Broad G-Series Compatibility — Confirmed fitment across G40, G50, G60, and G70 generators, including standard, mobile, and premium regional variants.
- Protects Engine Performance — A worn or skipped camshaft gear causes misfires, loss of power output, and hard starting; a correctly timed gear keeps the generator producing stable, clean power under load.
- Fuel System Timing Integrity — Proper camshaft gear engagement is critical to correct fuel delivery sequencing; using a spec-correct OEM gear prevents injection or carburetion timing drift that can damage valves and pistons.
The camshaft gear is a precision timing component that links the camshaft rotation to the crankshaft, ensuring the engine's intake and exhaust valves open and close at exactly the right moment in the combustion cycle. On a portable generator like the Wacker Neuson G-series, accurate valve timing directly determines power output quality, fuel efficiency, and the ability to maintain stable voltage under varying electrical loads. When the camshaft gear wears — typically through tooth wear, chipping, or backlash growth — timing drift causes rough running, increased fuel consumption, and in severe cases, valve contact with the piston crown.
