The Bomag 05715585 Piston Ring Set is a genuine OEM component designed for Bomag BW 75 AD and BW 75 ADL walk-behind rollers and BW 650 T, BW 850 T, BW 850 TR, BW 1050 T, and BW 85 T trench compactors. Sourced directly from Bomag, this piston ring set delivers the exact dimensions and material tolerances specified for these engines, ensuring a proper seal and correct compression from installation. This is the manufacturer-correct part for operators who need a dependable engine rebuild component without guesswork on fitment.
Key Features
- OEM Compression and Sealing Tolerances — manufactured to Bomag's exact ring gap, tension, and coating specifications, ensuring correct cylinder sealing and oil control from the first start-up
- Direct Engine Rebuild Fit — machined to the precise bore diameter required by the engine in these Bomag machines, dropping into place without modification during a standard piston overhaul
- Broad Model Coverage — fits BW 75 AD and BW 75 ADL walk-behind rollers and BW 650 T, BW 850 T, BW 850 TR, BW 1050 T, and BW 85 T trench compactors under a single part number 05715585
- Restored Engine Compression — worn or broken piston rings cause blow-by, oil consumption, and power loss; this set restores proper cylinder pressure so the engine runs at full output
- Genuine Bomag Quality Assurance — as an authentic OEM part, the piston ring set meets the material hardness and surface finish standards required for long service life in high-cycle compaction engines
A piston ring set seals the gap between the piston and the cylinder wall, performing three critical jobs: holding combustion pressure above the piston, scraping excess oil back down the cylinder bore, and transferring heat from the piston into the cylinder wall. When rings wear, lose tension, or break, combustion gases escape past the piston — a condition known as blow-by — which drops power output, increases fuel consumption, and allows oil to burn in the combustion chamber. Replacing the piston ring set during an engine overhaul restores proper compression and oil control, returning the engine to its designed power level and protecting the cylinder bore from accelerated wear.
