The Bomag 05743321 Glow Plug is a genuine OEM glow plug designed for a wide range of Bomag tandem rollers and single drum rollers, including the BW 120 AD-5, BW 100 AD-5, BW 138 AD-5, BW 124 DH-5, and BW 124 PDH-5. As a direct OEM replacement, this glow plug is built to the same specification as the original, ensuring proper cold-start ignition performance in diesel-powered Bomag equipment. It fits multiple BW-series models across the -5 generation lineup, covering AC, AD, SL, SLC, and PDH variants. Contact DHS Equipment to confirm fitment for your specific machine before ordering.
Key Features
- OEM-Spec Heating Element — manufactured to the original resistance and temperature output specification, delivering the precise heat needed for reliable diesel cold-start ignition
- Drop-In Replacement — engineered to match the original thread pitch, reach, and connector type for straightforward installation with no modification to the cylinder head
- Broad BW-Series Coverage — fits BW 100 and BW 120 series tandem rollers in AC, AD, SL, SLC, and ACW configurations, as well as BW 138 AD-5, BW 138 AC-5, BW 135 AD-5, BW 115 AC-5, BW 131 ACW-5, BW 124 DH-5, BW 124 PDH-5, and BW 120 AD-5 CC models
- Cold-Start Dependability — a correctly functioning glow plug brings the engine to firing temperature quickly; a worn or failed plug causes hard starting, excessive cranking, and engine stress in cold conditions
- Fuel System Safety — an out-of-spec glow plug can cause incomplete combustion, raw fuel buildup, and increased emissions; using a genuine OEM part keeps the fuel ignition cycle within safe operating parameters
A glow plug is a resistive heating element threaded into the pre-combustion or combustion chamber of a diesel engine. When the engine is started cold, the glow plug heats rapidly to raise the air temperature inside the cylinder, allowing the diesel fuel to ignite cleanly without relying on compression heat alone. On Bomag roller equipment, where engines may sit idle overnight or in cool weather on a jobsite, a functioning glow plug is essential for a fast, clean start. When a glow plug fails, the engine may crank repeatedly without firing, start with heavy white smoke, or fail to start altogether — accelerating wear on the starter motor and battery and delaying compaction work.
