The Bomag 05711194 Piston Ring Set is a genuine OEM component designed for the BW 212 D-2 single drum roller. Sourced directly from Bomag, this set delivers the exact ring geometry, material grade, and tension specification required by the engine in the BW 212 D-2 — ensuring a proper seal against the cylinder wall from the moment it is installed. If your machine is showing signs of worn rings — such as increased oil consumption, reduced compression, or excessive blowby — this is the correct OEM replacement to restore engine integrity.
Key Features
- OEM Compression Seal Integrity — manufactured to Bomag's exact ring tension and material tolerances, maintaining the combustion seal that keeps the engine producing full power
- Direct Engine Fitment — engineered to drop into the BW 212 D-2 cylinder bore without reworking or shimming, matching the OEM ring groove dimensions precisely
- Confirmed Compatibility — fits the BW 212 D-2 single drum roller; verify your machine's serial range before ordering to ensure correct application
- Restored Engine Performance — worn piston rings allow oil past the combustion chamber and bleed compression pressure; replacing this set brings cylinder sealing back to spec and recovers lost power output
- Fuel System Efficiency — a properly sealed combustion chamber supports correct fuel burn, helping the BW 212 D-2 maintain its designed fuel efficiency and reduce exhaust smoke
A piston ring set seals the gap between each piston and the cylinder wall, performing three critical jobs: containing combustion pressure to drive the piston downward, preventing engine oil from entering the combustion chamber, and transferring heat from the piston into the cylinder wall. When the rings wear, compression escapes past the piston, oil is burned in the combustion chamber, and the engine loses power while consuming more fuel. Replacing the rings with a correctly specified set — matched to the bore diameter and groove depth of the original engine — restores full cylinder pressure and stops oil burning before it leads to more serious engine damage.
