Key Features
- OEM Tooth Profile and Material Grade — manufactured to Bomag's exact gear geometry and hardness specifications, ensuring full load-bearing capacity and correct mesh engagement within the tandem roller drivetrain
- Drop-In Drivetrain Replacement — machined to OEM dimensions for direct installation, maintaining correct gear mesh and drum-drive engagement with no fitting adjustments
- Wide Tandem Roller Coverage — fits BW 141 AD-4, BW 151 AD-4, BW 154 AD-4, BW 161 AD-4, BW 190 AD-4, BW 202 AD-4, BW 203 AD-4, BW 205 AD 4, and their AM, AC, ADH, ADO, and EU-Flex variants
- Sustained Drive Performance — a worn or broken ring gear causes loss of drum drive and uneven compaction output; replacing with a correctly spec'd OEM gear restores full propulsion and compaction consistency
- Genuine Bomag OEM Part — supplied as an authentic Bomag replacement, backed by OEM quality assurance for professional service and maintenance requirements
The ring gear is a core element of the drum drive system in a tandem roller, transmitting rotational force from the drive motor to the drum to propel and rotate it during compaction passes. It works under continuous high-load cycling, and wear or tooth damage can cause slipping, erratic drum movement, or complete loss of drive — directly compromising compaction quality and machine control. Replacing a worn ring gear with a correctly profiled OEM component restores full drivetrain integrity and keeps the roller performing to its rated output.
