The Bomag 05748709 Oil Pressure Switch is a genuine OEM component designed for the BW 900-50 walk-behind roller. Sourced directly from Bomag, this switch carries the same specifications as the original part installed at the factory, ensuring an exact match for the application. This oil pressure switch installs directly into the engine lubrication circuit of the BW 900-50, delivering the accurate pressure sensing your machine depends on for safe, continuous operation.
Key Features
- Genuine OEM Pressure Sensing Accuracy — calibrated to the correct activation threshold for the BW 900-50 engine, so the switch triggers at the right pressure — not too early, not too late
- Direct OEM Replacement — matches the original thread pitch, electrical connector, and pressure rating of the factory-installed unit for a straightforward swap
- Confirmed Fitment — verified for the Bomag BW 900-50 walk-behind roller; use part number 05748709 to ensure you are ordering the correct switch for your machine
- Engine Protection Built In — a correctly functioning oil pressure switch alerts the operator or shuts down the engine before low-pressure conditions cause internal bearing and cylinder damage
- Electrical Integrity — genuine OEM construction ensures stable resistance and contact reliability, preventing false warnings or missed alerts that can result from worn or non-spec switches
An oil pressure switch monitors the lubrication pressure inside the engine and sends a signal to the warning system or engine cut-off circuit when pressure drops below a safe threshold. On a walk-behind roller like the BW 900-50, this protection is critical — without it, low oil pressure can go undetected long enough to cause serious internal engine damage. When the switch fails, the operator may receive a constant false warning, no warning at all, or an engine that refuses to start, all of which point to the need for an immediate replacement with a correct-spec part like the Bomag 05748709.
