The Bomag 421013025 Relay is a genuine OEM electrical relay designed for Bomag pavers and cold milling machines, including the BF 600, BF 700, BF 800, and BF 900 paver series as well as BM 1000/30-2, BM 1200 30-2, BM 1300/30-2, and BM 2000/60-2 cold milling machines. Sourced directly from Bomag, this relay matches the original component specification for a correct, hassle-free installation. Confirming part number 421013025 against your machine's parts manual before ordering ensures the right fit for your specific model variant.
Key Features
- Genuine OEM Electrical Spec — matches the original switching voltage and current ratings so circuits operate exactly as Bomag engineered them, with no risk of under- or over-rated relay behavior
- Drop-In Replacement — shares the same connector footprint and mounting configuration as the factory relay, seating directly into the existing socket without adapter wiring
- Broad Paver Coverage — fits a wide range of Bomag pavers including BF 600 C HCG, BF 600 P-2 S 600, BF 700 C-2 S 600, BF 800 C S600-4i, BF 900 C S600-4i, and additional BF-series variants listed in the fitment data
- Cold Milling Machine Compatibility — also fits Bomag cold milling machines including BM 1000/30-2, BM 1200 30-2, BM 1300/30-2, and BM 2000/60-2, making part number 421013025 a versatile stock item for mixed Bomag fleets
- Electrical Circuit Integrity — a failed or degraded relay can cause intermittent or total loss of the circuit it controls, leading to unpredictable machine behavior; replacing it with the correct OEM unit restores consistent, predictable electrical switching
- Fuel and Ignition System Safety — relays on pavers and milling machines often govern fuel shutoff or ignition circuits; using the correct OEM-rated component maintains proper circuit protection and safe machine shutdown behavior
A relay is an electrically operated switch that allows a low-current control signal — from a switch, sensor, or control module — to safely open or close a high-current circuit powering a motor, solenoid, or other heavy load. In Bomag pavers and cold milling machines, relays are used throughout the electrical system to control functions such as engine starting, fuel delivery, hydraulic solenoids, and auxiliary systems. When a relay fails, the circuit it controls may stop functioning entirely or behave erratically, making accurate diagnosis and replacement with the correct OEM part essential to restoring normal machine operation.
