The Bomag 05710309 Flywheel is a genuine OEM component designed for the BW 120 AD tandem roller. Sourced directly from Bomag, this flywheel carries the same specifications as the part originally installed at the factory, ensuring a correct, reliable fit. This component is the right choice for operators and shop technicians restoring engine performance on BW 120 AD tandem rollers and want confidence in the part going in.
Key Features
- Genuine OEM Mass and Balance Spec — manufactured to Bomag's exact rotational mass and balance tolerances, critical for smooth engine operation and crankshaft longevity
- Direct Engine Drop-In — engineered to match the original mounting pattern and ring gear interface on the BW 120 AD, so installation follows the standard service procedure without adaptation
- Confirmed Fitment — verified for the BW 120 AD tandem roller under Bomag part number 05710309
- Sustained Engine Smoothness — a correctly matched flywheel stabilizes crankshaft rotation and maintains even power delivery to the drivetrain, preserving performance across the compaction cycle
- Clutch Engagement Integrity — the flywheel's friction surface condition directly affects clutch engagement quality; an OEM replacement restores full, consistent torque transfer where a worn unit causes slip or chatter
The flywheel is a heavy rotating disc mounted directly to the engine crankshaft. Its primary job is to store rotational energy between power strokes, smoothing out engine pulses and keeping the drivetrain turning evenly under load. On a tandem roller like the BW 120 AD, consistent power delivery matters — any imbalance or wear in the flywheel translates directly into rough running, vibration, and degraded compaction performance. When a flywheel cracks, loses ring gear teeth, or develops a worn friction face, the engine becomes difficult to start, clutch engagement suffers, and the machine may vibrate excessively — replacing it promptly with a correctly spec'd OEM part restores normal operation.
