The Wacker Neuson is a genuine OEM Oil Pressure Switch designed for the G40, G50, G60, G70, G95, and G110 series portable generators. As a factory-authorized component, it is manufactured to the exact specifications required by Wacker Neuson, ensuring correct sensor response thresholds and reliable integration with the generator's protection circuitry. This switch fits a wide range of GP-series models across standard, premium, and Brazil-market configurations, making it the correct choice whether you're servicing a North American unit or a 50 Hz LATAM-spec machine. Keep part number on hand for scheduled maintenance or unplanned switch failures to get your generator back online fast.
Key Features
- Correct Pressure Threshold Calibration — Manufactured to OEM-specified activation pressure, so the engine protection system responds accurately — not too early, not too late.
- Direct-Fit Replacement — Matches the original threaded port connection and wiring interface on G-series generators for a straightforward swap with standard hand tools.
- Broad G-Series Compatibility — Verified fitment across G40, G50, G60, G70, G95, and G110 generator models, including standard, mobile, premium, and Brazil-market variants.
- Engine Protection You Can Count On — A correctly functioning oil pressure switch triggers an automatic shutdown before low-oil conditions cause internal engine damage, protecting a significant capital asset.
- Critical Safety Component — In fuel-powered generators, oil pressure monitoring is a primary safeguard against catastrophic engine seizure; using a properly rated OEM switch maintains the integrity of that protection.
The oil pressure switch monitors engine oil pressure in real time and sends a signal to the generator's control system. When oil pressure drops below the safe operating threshold — due to low oil level, a failing pump, or a leak — the switch triggers an automatic engine shutdown, preventing serious internal damage. A faulty or out-of-spec switch can either fail to protect the engine when pressure drops, or cause nuisance shutdowns when pressure is actually normal, both of which lead to costly downtime and potential engine damage.
