The Bomag 05740444 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 delivers the exact dimensions and material specification required for a correct, lasting installation. Confirmed fitment across the BW 80 and BW 90 series tandem roller family means you can order with confidence that this component matches your machine.
Key Features
- Genuine OEM Precision — manufactured to Bomag's exact tolerances, ensuring the piston seals and moves within the cylinder bore with the same performance as the original part it replaces.
- Direct-Fit Replacement — matches the original piston profile, ring grooves, and pin bore dimensions so it installs into your engine assembly without modification.
- Broad 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 across the BW series.
- Engine Output Protection — a correctly fitted piston maintains proper compression, allowing the engine to deliver full power and consistent vibration output during asphalt compaction passes.
- Fuel System Integrity — proper piston condition is critical to combustion efficiency; a worn or damaged piston causes compression loss, increased fuel consumption, and excessive oil burning that shortens engine life.
The piston is a core reciprocating component inside the engine cylinder, converting combustion pressure into the crankshaft rotation that powers the entire machine. It must maintain a precise seal against the cylinder wall through its piston rings to preserve compression and keep oil and combustion gases from mixing. When a piston wears, cracks, or loses ring integrity, the engine experiences a drop in compression, rough running, excessive smoke, and ultimately the loss of power needed to drive the vibratory drums on tandem rollers like the BW 80 AD-2 and BW 100 ADM-2.
