The Bomag 05702581 Diesel Engine is a genuine OEM replacement built for Bomag tandem rollers, including the BW 190 AD-4, BW 190 AD-4 AM, BW 202 AD-4, BW 202 AD-4 EU-Flex, BW 203 AD-4, BW 203 AD-4 AM, BW 203 AD-4 AM EU-Flex, BW203AD-4, BW 203 ADO-4, and BW 205 AD 4. Sourced directly from Bomag, this engine meets the same specifications as the original unit installed at the factory, ensuring a direct swap with no guesswork on compatibility. When your tandem roller is down, this replacement diesel engine gets you back to productive compaction work with confidence in the fit and function.
Key Features
- Genuine OEM Engine Assembly — supplied directly by Bomag, this diesel engine matches the original power output, mounting configuration, and system interfaces of the unit it replaces
- Direct-Fit Replacement — engineered to drop into Bomag tandem roller frames without modification, preserving correct alignment of the drivetrain, hydraulics, and cooling connections
- Broad Tandem Roller Coverage — confirmed fitment across the BW 190 AD-4, BW 202 AD-4, BW 203 AD-4, BW 205 AD 4, and related AM, EU-Flex, and ADO-4 variants
- Restored Power and Compaction Performance — a healthy diesel engine maintains the drum drive pressure and travel speed that tandem rollers depend on for consistent asphalt compaction passes
- Fuel System Integrity — as the heart of the machine's fuel and combustion system, an OEM-spec engine ensures correct injection timing and emissions compliance for your operating region
The diesel engine is the primary power source for the tandem roller, driving both the vibratory drum system and the hydraulic circuits that control travel, steering, and drum amplitude. A worn or failing engine causes loss of drum exciter force, reduced travel speed, and inconsistent compaction results that can compromise mat quality on asphalt paving jobs. Replacing a failed engine with a genuine Bomag unit restores full operating capacity and ensures all auxiliary systems receive the hydraulic flow and mechanical drive they need to function correctly.
