The Bomag 05740124 Piston is a genuine OEM component designed for Bomag BW 80 AD-2, BW 90 AD-2, BW 100 ADM-2, BW 80 ADS, and BW 90 AC-2 tandem rollers. Sourced directly from Bomag, this piston meets the original engineering specifications for these machines, ensuring a correct, consistent fit every time. As an authentic OEM part, it carries the same design tolerances as the component originally installed at the factory, giving operators and service technicians confidence that the repair is done right. Fitment is confirmed across the BW 80 AD-2, BW 90 AD-2, BW 100 ADM-2, BW 80 ADS, and BW 90 AC-2 tandem roller models.
Key Features
- OEM Dimensional Accuracy — Manufactured to Bomag's original bore, ring groove, and compression height specifications for this piston, ensuring proper sealing and combustion efficiency.
- Direct Replacement Fit — Installs into the engine cylinder bore using the same orientation and hardware as the original, with no adaptation needed at the machine level.
- Confirmed Tandem Roller Coverage — Compatible with BW 80 AD-2, BW 90 AD-2, BW 100 ADM-2, BW 80 ADS, and BW 90 AC-2 tandem rollers, covering multiple variants in the BW compact tandem lineup.
- Restored Engine Compression — A correctly spec'd piston maintains proper cylinder pressure, enabling the engine to deliver the power output these tandem rollers depend on for consistent drum vibration and drive performance.
- Genuine Bomag OEM Part — Supplied under part number 05740124 as an authentic Bomag component, eliminating guesswork about compatibility or material grade when sourcing engine internals.
The piston is a core reciprocating component inside the engine cylinder, converting combustion pressure into the crankshaft rotation that powers the machine. It works in conjunction with piston rings and the cylinder wall to maintain compression and control oil consumption — both critical to engine efficiency and longevity. When a piston wears, cracks, or loses its ring land integrity, compression drops, oil burns off at an elevated rate, and engine output becomes inconsistent, directly affecting the compaction performance of the roller.
