The Bomag 83211842 Resistor is a genuine OEM electrical component designed for Bomag BW 213, BW 177, and BW 145 series single drum rollers, including the BW 213 PDH-40, BW 213 DH-40, BW 177 DH-40, BW 177 PDH-40, BW 145 DH-40, and BW 145 PDH-40. Sourced directly from Bomag, this resistor carries the same specifications as the original unit installed at the factory, ensuring correct electrical behavior across the supported machine lineup. When your single drum roller's resistor fails or reads out of spec, replacing it with part number 83211842 restores proper circuit function without guesswork or adaptation.
Key Features
- OEM-Matched Resistance Specification — manufactured to the exact resistance value required by Bomag's electrical system, eliminating the risk of over- or under-current conditions that an off-spec component can introduce.
- Drop-In Electrical Replacement — connects directly to the existing wiring harness using the original mounting configuration, making swap-out straightforward for qualified technicians.
- Broad BW Series Coverage — fits BW 213 PDH-40, BW 213 DH-40, BW 177 PDH-40, BW 177 DH-40, BW 145 DH-40, BW 145 PDH-40, and additional BW 145 single drum roller variants.
- Protects Downstream Electrical Components — a correctly rated resistor limits current flow to sensitive control circuits; a failed or incorrect resistor can cause erratic behavior or damage to connected components.
- Genuine Bomag OEM Part — backed by Bomag's OEM supply chain, so you receive the same component that was engineered and validated for these machines from the start.
A resistor regulates the flow of electrical current within a circuit by opposing voltage and limiting the amount of current that reaches connected components. In Bomag single drum rollers, resistors are commonly used in control circuits, fan motor speed regulation, and instrument systems to maintain correct operating parameters. When a resistor degrades or fails completely, it can cause connected components to receive too much or too little current, leading to erratic machine behavior, component damage, or a complete loss of function in the affected circuit — making timely replacement with the correct OEM part essential for keeping the machine running as designed.
