The Bomag 05718812 Piston Ring is a genuine OEM component designed for the BW 212 D-2 single drum roller and BC 601 RB refuse/landfill compactor. Sourced directly from Bomag, this piston ring matches the original part in material, dimensions, and tolerancing — ensuring proper cylinder sealing and engine performance from the first hour of operation. If you're replacing a worn or broken ring on either of these machines, part number 05718812 is the correct OEM specification replacement.
Key Features
- OEM Cylinder Sealing Spec — manufactured to Bomag's original ring geometry and metallurgy, delivering the correct compression seal and oil control your engine depends on
- Direct Engine Drop-In — engineered to the exact bore diameter and ring groove dimensions of the original, fitting straight into the piston without machining or shimming
- Broad Machine Coverage — fits the BW 212 D-2 single drum roller and the BC 601 RB refuse/landfill compactor, covering two distinct heavy equipment families with one genuine part
- Compression Integrity Restored — a correctly seated piston ring maintains cylinder pressure, preserving engine power output and protecting against oil blow-by and accelerated wear
- Fuel System Protection — proper ring sealing prevents combustion gases from entering the crankcase, protecting engine oil from contamination and extending overall engine service intervals
A piston ring seals the gap between the piston and the cylinder wall, serving two critical functions: maintaining combustion pressure so the engine produces full power, and controlling oil so it lubricates the cylinder without burning off into the combustion chamber. When a piston ring wears thin, cracks, or loses tension, compression drops, oil consumption rises, and exhaust smoke increases — symptoms that will eventually escalate into serious engine damage if left unaddressed. Replacing a failed ring with the correct OEM part, such as this Bomag 05718812, restores the cylinder's sealed environment and brings engine performance back to specification.
