The Wacker Neuson Intake Valve is a genuine OEM component designed for the G40, G50, G60, G70, G95, and G110 series portable generators. Sourced directly from Wacker Neuson, this intake valve meets the exact specifications of the original part installed at the factory. It is compatible across a wide range of GP generator configurations, including standard, mobile, 50Hz LATAM, and Brazil market variants. If your generator is experiencing rough running, loss of power, or compression issues, replacing a worn intake valve with part number restores proper engine performance.
Key Features
- Genuine OEM Valve Geometry — Manufactured to the exact seat angle, stem diameter, and head dimensions of the original, ensuring correct sealing and compression retention in the engine cylinder head.
- Direct Drop-In Replacement — Matches the original valve stem length and keeper groove configuration for straightforward installation without modification to the valve train.
- Broad Generator Family Coverage — Fits G40, G50, G60, G70, G95, and G110 series Wacker Neuson portable generators across multiple configurations and regional variants.
- Restored Engine Compression — A correctly seated intake valve maintains the cylinder's compression ratio, allowing the generator to start reliably and deliver consistent power output under load.
- Fuel Efficiency Protection — A worn or leaking intake valve allows unburned air/fuel mixture to escape, increasing fuel consumption and reducing output; replacing it with part 5200021164 corrects this condition.
The intake valve controls the flow of the air/fuel mixture into the engine's combustion chamber during the intake stroke. It opens to admit the charge and seals tightly during compression and combustion to contain cylinder pressure. When an intake valve wears, burns, or fails to seat properly, the result is reduced compression, hard starting, misfiring, and a noticeable drop in generator power output. Replacing a damaged intake valve promptly prevents further damage to the cylinder head, valve seat, and piston.
