The Bomag 05742706 Glow Plug is a genuine OEM component designed for Bomag tandem rollers across the BW 100, BW 120, BW 125, and BW 131 series, including the BW 100 AD-4, BW 100 AC-4, BW 100 AD-5, BW 100 AC-5, BW 120 AD-4, BW 120 AC-4, BW 120 AD-5, BW 120 AC-5, BW 125 AD-4, BW 125 AC-4, BW 120AD 4, and BW 131 AD-5. Sourced directly from Bomag, this glow plug meets the exact OEM specification for your machine's diesel engine. A worn or failed glow plug can cause hard starts, misfires, and rough running — particularly in cold conditions — so replacing it with a correct OEM part keeps your roller starting clean and running consistently.

- Broad Tandem Roller Coverage — fits BW 100, BW 120, BW 125, and BW 131 tandem rollers across both the -4 and -5 generation lines, including AC and AD drive variants
- Protects Engine Longevity — a correctly functioning glow plug ensures clean ignition, preventing the unburnt fuel deposits and excess wear that result from repeated failed start attempts
- Genuine Bomag OEM Part — supplied as original equipment, so you get the same component installed at the factory, verified by part number 05742706
A glow plug is a small electric heating element threaded into each cylinder of a diesel engine. Before the engine cranks, it pre-heats the combustion chamber so the compressed air-fuel mixture ignites reliably — a step that is critical in cold weather or after extended downtime. When a glow plug fails or degrades, the engine struggles to start, runs roughly at low temperatures, and may produce excessive smoke until the cylinder reaches operating temperature. Replacing a faulty glow plug promptly restores clean ignition and protects the engine from the strain of prolonged cranking.
