The Bomag 05711523 Piston is a genuine OEM component designed for the BW 172 D-2 single drum roller. Sourced directly from Bomag, this piston meets the original engineering specifications the BW 172 D-2 was built around, ensuring a correct, drop-in installation without guesswork. Whether you are overhauling an engine or replacing a worn component, this OEM piston delivers the dimensional accuracy and material grade the application demands. Confirm part number 05711523 against your machine's parts documentation before ordering to ensure a proper match.
Key Features
- OEM-Grade Metallurgy — Manufactured to Bomag's original material and dimensional specifications, with the precise bore diameter, ring-groove geometry, and crown profile required for consistent compression and combustion performance.
- Direct Installation — Engineered as an exact replacement for the BW 172 D-2, this piston installs into the original cylinder bore without modification to clearances or ring sets.
- Confirmed Fitment — Verified for the Bomag BW 172 D-2 single drum roller; reference part number 05711523 in your Bomag parts catalog to confirm compatibility with your machine's serial range.
- Sustained Compression Integrity — A correctly fitted piston maintains proper cylinder sealing, supporting full engine power output and fuel efficiency across demanding compaction cycles.
- Protects Downstream Components — An out-of-spec or worn piston accelerates cylinder wall wear, increases oil consumption, and can lead to costly engine damage; replacing with a genuine OEM part keeps wear within design limits.
The piston is a core reciprocating engine component that transfers combustion force to the crankshaft via the connecting rod, driving the power output that runs the BW 172 D-2's vibratory and propulsion systems. It must maintain a precise fit within the cylinder bore to seal combustion gases above and allow controlled oil lubrication below. When a piston wears, cracks, or loses its ring-groove integrity, the engine loses compression, burns oil, and delivers reduced drum force — symptoms that compound quickly under the sustained load of soil compaction work.
