The Bomag 05767386 Marginal Relay is a genuine OEM component designed for Bomag tandem rollers including the BW 80 AD-5, BW 90 AD-5, BW 90 SC-5, BW 100 AD-5, BW 100 ADM-5, BW 100 SC-5, BW 100 SL-5, BW 120 AD-5, BW 120 SL-5, BW 120 SLC-5, and BW 120SL-5. Sourced directly from Bomag, this relay matches the original specification so it seats and connects exactly as the factory component did. It is the correct choice when restoring proper electrical function to the machines listed above.
Key Features
- OEM Electrical Precision — manufactured to Bomag's exact switching specification, ensuring correct actuation thresholds and contact ratings for the marginal relay circuit
- Direct Drop-In Fit — this relay connects to the factory harness and mounting position without modification, matching the original form factor of part number 05767386
- Broad Tandem Roller Coverage — confirmed fitment across the BW 80 AD-5, BW 90 AD-5, BW 90 SC-5, BW 100 AD-5, BW 100 ADM-5, BW 100 SC-5, BW 100 SL-5, BW 120 AD-5, BW 120 SL-5, BW 120 SLC-5, and BW 120SL-5 tandem rollers
- Electrical System Integrity — a properly functioning marginal relay keeps the machine's control circuit operating within its designed switching boundaries; a failed relay can cause erratic behavior or system faults that halt compaction work
- Genuine Bomag Quality — supplied as an authentic OEM part, giving you the same service life and performance as the component it replaces
The marginal relay is an electrical switching component within the machine's control circuitry, responsible for managing a specific load or signal at the boundary of normal operating parameters — hence the "marginal" designation. It acts as a gatekeeper, opening or closing a circuit when voltage or current reaches a defined threshold, protecting downstream components from out-of-range conditions. When this relay fails or becomes intermittent, the affected circuit may not switch correctly, leading to unexpected shutdowns, warning faults, or loss of function in the system it controls.
