The Bomag 05831004 Oil Pressure Switch is a genuine OEM component designed for a wide range of Bomag compaction equipment, including the BW 90 AD tandem roller, BW 65 walk-behind rollers, BMP 851 trench compactor, and multiple BPR and BPH series reversible vibratory plates. As a factory-sourced part, this oil pressure switch matches original specifications exactly, ensuring it integrates seamlessly into the engine monitoring circuit of compatible machines. Confirmed fitment covers models including the BPR 65/52 D-3, BPR 75/60 D, BPR 50/52 D, BPH 80/65, and BPH 80/65 S, among others. When an oil pressure switch fails or reads inaccurately, it puts the engine at risk — replacing it with the correct OEM part restores dependable protection across every compatible machine in your fleet.
Key Features
- Genuine OEM Sensing Accuracy — factory-calibrated to the correct pressure threshold for Bomag engines, so the switch triggers at precisely the right point to protect against low-oil conditions
- Direct-Fit Replacement — matches the original connector, thread pitch, and port size for a straightforward swap with no adaptation on BW, BPR, BPH, and BMP series machines
- Broad Fleet Coverage — fits the BW 90 AD tandem roller, BW 65, BW 65 S-2, BW 65-H, BW 65 H, and BW 62 H walk-behind rollers, the BMP 851 trench compactor, and reversible vibratory plates including the BPR 50/52 D, BPR 50/52 D-2, BPR 50/52 D-3, BPR 65/52 D-3, BPR 75/60 D, BPH 80/65, and BPH 80/65 S
- Engine Protection Restored — a functioning oil pressure switch is the first line of defense against catastrophic engine damage; a failed or drifted switch can allow an engine to run unprotected or cause nuisance shutdowns that interrupt compaction work
- Electrical Safety Compliance — OEM construction ensures correct resistance and circuit behavior within Bomag's engine management and warning systems, preventing false readings that could mask a genuine low-pressure event
The oil pressure switch monitors engine oil pressure in real time and signals the machine's warning or shutdown system when pressure drops below a safe operating level. It acts as a critical safeguard, giving the operator or control system time to respond before low oil pressure causes internal engine damage. When this switch wears, corrodes, or fails, it can either allow the engine to run dangerously low on pressure without warning or trigger unnecessary shutdowns — either outcome disrupts work and risks costly repairs.
