The Bomag 05741390 Generator is a genuine OEM component designed for Bomag BW 100, BW 120, BW 135, and BW 138 tandem rollers, as well as BW 124 single drum rollers. As a factory-sourced part, this generator meets the original design specifications Bomag built into these machines, ensuring correct electrical output and seamless integration with the onboard systems. Confirmed fitment includes the BW 100 AD-4, BW 100 AC-4, BW 120 AD-4, BW 120 AC-4, BW 135 AD-5, BW 138 AC-5, BW 138 AD-5, BW 124 PDH-5, and BW 124 DH-5.
Key Features
- OEM-Matched Electrical Output — sourced directly from Bomag, this generator delivers the correct voltage and amperage specification your machine's electrical system depends on, with no guesswork on compatibility
- Drop-In Replacement — engineered to the original mounting configuration and connector interface, this generator installs directly using existing hardware and wiring on compatible machines
- Broad Tandem and Single Drum Coverage — fits the BW 100 AD-4, BW 100 AC-4, BW 120 AD-4, BW 120 AC-4, BW 135 AD-5, BW 138 AC-5, BW 138 AD-5, BW 124 PDH-5, and BW 124 DH-5
- Sustained Electrical System Integrity — a functioning generator keeps the battery charged and powers all onboard electrical systems; a failing unit can cause erratic instrument behavior, battery drain, and unexpected shutdowns mid-operation
- Genuine Bomag Part — part number 05741390 is an authentic OEM component, not a generic substitute, giving you the confidence that form, fit, and function match what left the factory
The generator on a Bomag roller is responsible for converting mechanical engine energy into electrical power, keeping the battery charged and supplying current to the machine's lights, controls, and electronic systems during operation. When the generator begins to fail, operators may notice warning lights, dimming instrumentation, or a battery that drains between shifts — all signs that the electrical supply has become unreliable. Replacing a worn generator with a correct OEM unit like the Bomag 05741390 restores stable electrical output and prevents secondary damage caused by undervoltage conditions across the machine's systems.
