The Bomag 05702501 Diesel Engine is a genuine OEM diesel engine designed for BW 161 AD-4, BW 161 AC-4, BW 161 ADO-4, and BW 161 AD-4 EU-Flex tandem rollers. Sourced directly from Bomag, this engine assembly is built to the exact specifications required by these machines, ensuring correct mounting, output ratings, and system integration. If your tandem roller is losing power, running rough, or has suffered an engine failure, this is the authorized replacement component your machine was built around.
Key Features
- Genuine OEM Engine Assembly — sourced directly from Bomag to match the original power output, displacement, and interface specifications of the BW 161-series tandem roller platform
- Exact-Match Replacement — engineered to drop into the same mounting envelope and connect to existing fuel, cooling, electrical, and drive systems without improvisation
- Confirmed Tandem Roller Fitment — compatible with BW 161 AD-4, BW 161 AC-4, BW 161 ADO-4, and BW 161 AD-4 EU-Flex tandem rollers, covering multiple drive and emissions configurations within the BW 161 family
- Full Power Delivery Restored — a correctly matched engine ensures the roller maintains the hydraulic pressure and drum vibration output needed for consistent asphalt compaction pass after pass
- Emissions and Fuel System Compliance — the OEM engine unit preserves the original fuel system calibration and emissions configuration, which is critical for EU-Flex and regulated-market machines
The diesel engine is the primary power source for the tandem roller, driving both the propulsion system and the hydraulic circuits that power drum vibration and steering. When the engine is worn, damaged, or has failed, the roller cannot generate the consistent compactive effort needed for quality asphalt work — drum frequency drops, travel speed becomes uncontrollable, and the machine may not start at all. Replacing a failed engine with the correct OEM unit restores full hydraulic flow and rated power output, bringing the machine back to the performance level it was designed to deliver.
