Wacker Neuson 5000075790 Oil Alert Switch Assembly

The Wacker Neuson is a genuine OEM Oil Alert Switch Assembly designed for a wide range of Wacker Neuson concrete trowels, portable generators, trash pumps, floor saws, and power buggies. As a factory-sourced component, it delivers the exact fit and electrical characteristics required by the original equipment design. Compatible models include CT and CRT series walk-behind and ride-on trowels, GP, GPS, GS, GV, and G-series portable generators, PT3A trash pumps, BFS floor saws, WB16 power buggies, BPU reversible vibratory plates, and more. Keeping this switch in proper working condition is essential to protecting your engine investment across all supported equipment families.

Key Features

• Genuine OEM Electrical Accuracy — Factory-sourced switch assembly with the correct trigger threshold and circuit characteristics to activate the oil alert system at the intended oil pressure or level point.
• Direct-Fit Installation — Matches the original connector, thread spec, and mounting configuration, so the switch installs directly into the existing port without modification.
• Broad Cross-Equipment Compatibility — A single part number covers CT/CRT trowels, GP/GPS/GV/G-series generators, PT3A trash pumps, BFS floor saws, WB16 power buggies, and select BPU vibratory plates — simplifying parts inventory across your fleet.
• Engine Protection When It Counts — A correctly functioning oil alert switch triggers automatic engine shutdown before low-oil conditions cause internal damage; a failed switch leaves the engine running unprotected.
• Verified OEM Part Number — Part number 5000075790 is the authoritative Wacker Neuson reference for this switch assembly across all listed machine families, ensuring you receive the correct component every time.

The oil alert switch assembly monitors engine oil level or pressure and sends a signal to the machine's control circuit to shut the engine down automatically when oil drops below a safe threshold. This protection is critical on equipment that may run unattended or in conditions where the operator cannot always monitor engine status closely. When the switch fails — whether it sticks open, sticks closed, or loses electrical continuity — the engine either shuts off unnecessarily or, more dangerously, continues running with critically low oil, risking seizure and costly internal damage.
