The Bomag 05740496 Oil Pressure Switch is a genuine OEM component designed for a wide range of Bomag BW tandem rollers and BMP 8500 trench compactors. Sourced directly from Bomag, this switch matches the original manufacturer's specifications, ensuring the correct electrical characteristics and thread fitment for a seamless installation. Confirmed fitment spans models including the BW 80 AD-2, BW 100 AD-5, BW 120 AD-5, BW 138 AD-5, BW 174 AP-4, BW 177 D-5, BW 177 DH-5, BMP 8500, and BMP 8500 Kubota, among many others across the BW tandem and single drum roller lines. Ordering by part number 05740496 ensures you receive the correct switch for your machine without guesswork.
Key Features
- OEM-Calibrated Switching Threshold — manufactured to Bomag's original pressure-sensing specification, so the switch opens and closes at the correct oil pressure values for your engine's protection system
- Direct Thread-and-Connector Fit — matches the original port thread size and electrical connector on covered Bomag models, allowing straightforward installation without adapters or modifications
- Broad Bomag Coverage — fits an extensive range of BW tandem rollers from the BW 80 AD-2 through the BW 174 AP-4 and BW 151 AD-50 series, plus BW 177 D-5 and BW 177 DH-5 single drum rollers and BMP 8500 trench compactors
- Engine Protection Integrity — a correctly functioning oil pressure switch triggers the warning system or shutdown the moment oil pressure drops below safe limits, preventing costly engine damage during operation
- Safety-Critical Replacement — a failed or out-of-spec pressure switch can mask low-oil conditions entirely, leaving the engine unprotected; replacing with genuine OEM part number 05740496 restores the full warning and shutdown response
The oil pressure switch monitors engine lubricating oil pressure and sends an electrical signal to the machine's instrument panel or control system. When oil pressure falls below the safe operating threshold, the switch triggers a warning light or initiates an automatic engine shutdown, protecting internal engine components from running dry. A worn or failed switch can either prevent the warning from activating when pressure is genuinely low, or cause false alarms that interrupt productive work — either way, replacing it promptly with the correct OEM unit keeps the engine monitoring system working as Bomag intended.
