The Wacker Neuson Oil Sensor Complete is a genuine OEM component designed for CT36-9 and CT48-9 walk-behind concrete power trowels, GP4000, GPi4300, and GPSi4300 portable generators, and the BPU 3050 reversible vibratory plate compactor. As a direct OEM replacement, the is manufactured to the same exacting standards as the original part, ensuring accurate oil-level detection and consistent engine protection across all compatible machines. Sourced directly from Wacker Neuson, this complete sensor assembly is ready to install and restore full oil-monitoring functionality without guesswork or adaptation.
Key Features
- Genuine OEM Sensor Accuracy — Manufactured to the original electrical specification, this sensor delivers the same resistance and switching threshold as the factory-installed unit, so your engine protection system responds exactly as intended.
- Complete Assembly — Supplied as a full Oil Sensor Complete unit, meaning all necessary sensor components are included for a straightforward swap-out without sourcing additional hardware.
- Broad Cross-Family Fitment — Verified for CT36-9 and CT48-9 walk-behind concrete trowels, GP4000, GPi4300, and GPSi4300 portable generators, and the BPU 3050 reversible vibratory plate — one part number covering multiple Wacker Neuson machine families.
- Engine Protection Restored — A functioning oil sensor is what triggers an automatic engine shutoff before low-oil conditions cause internal damage; replacing a failed sensor keeps that critical safety loop intact.
- Low-Oil Shutdown Compliance — On generators and trowels alike, a faulty oil sensor can defeat the low-oil shutoff circuit entirely, leaving the engine exposed to damage without warning — replacing it with a genuine OEM unit restores that protection.
The oil sensor monitors engine oil pressure or level and sends a signal to the machine's control circuit to shut down the engine if oil drops below a safe threshold. This protects the engine from catastrophic internal damage caused by oil starvation — a failure mode that can be sudden and expensive. When the sensor itself fails, either through electrical fault or physical damage, the shutoff circuit may stop working correctly, or a false low-oil reading may prevent the machine from starting at all; replacing the sensor with a correct OEM unit like the 5000210104 restores normal operation and engine protection.
