The Bomag 05712943 Cylinder Liner is a genuine OEM component designed for Bomag BC-series refuse and landfill compactors and MPH-series recyclers and stabilizers. Sourced directly from Bomag, this cylinder liner delivers the exact dimensional tolerances and material grade required to maintain engine integrity across the BC 772 RB, BC 772 RS, BC 672 RB, BC 1172 RB, MPH 121, and MPH 122. As a direct OEM replacement, this part matches the original specification without adaptation, ensuring a correct installation on every covered machine. Whether you are overhauling a high-hour engine or restoring compression after liner wear, this component is the right choice for keeping your equipment working at full capacity.
Key Features
- OEM-Grade Bore Precision — manufactured to Bomag's original dimensional tolerances, ensuring correct piston-to-liner clearance and consistent compression across the engine's service life
- Direct-Fit Replacement — engineered to seat exactly as the original liner, with matching flange dimensions and surface finish that allow straightforward installation
- Broad Coverage Across Bomag Heavy Equipment — fits the BC 772 RB, BC 772 RS, BC 672 RB, and BC 1172 RB refuse and landfill compactors, as well as the MPH 121 and MPH 122 recyclers and stabilizers
- Sustained Engine Performance — a correctly fitted cylinder liner maintains proper compression and oil control, supporting full power output and fuel efficiency on demanding compaction and stabilization work
- Genuine Bomag OEM Part — supplied under part number 05712943 with the confidence that comes from an authentic Bomag component, not a reverse-engineered substitute
A cylinder liner forms the wear surface inside the engine block within which the piston travels, sealing combustion gases above and controlling oil film below. Over time, liner walls wear, score, or develop out-of-round profiles that allow combustion pressure to bypass the piston rings, causing power loss, excessive oil consumption, and elevated exhaust emissions. Replacing a worn liner with the correct OEM part restores the engine's original bore geometry, allowing new piston rings to seat properly and the engine to return to its rated output — critical for the sustained heavy-duty demands placed on refuse compactors and recycler-stabilizer machines.
