The Bomag 05717920 Piston Ring Set is a genuine OEM component designed for a wide range of Bomag pavers, single drum rollers, tandem rollers, pneumatic tyred rollers, and cold milling machines. This piston ring set is engineered to OEM specification, delivering the correct ring geometry, material grade, and tension profile for the engine configurations found across the BF, BW, and BM equipment families. Confirmed fitment includes machines such as the BF 691 C, BF 800 C S500, BF 800 C S600, BF 800 P S500, BW 219 D-5, BW 226 PDH-5, BW 202 AD-4, BW 203 AD-4, BW 27 RH, BM 500/15, and BM 600/15, among many others. Sourcing a genuine Bomag replacement ensures the engine maintains proper compression and oil control without the guesswork of cross-referencing non-OEM alternatives.
Key Features
- OEM Compression and Oil Control Tolerances — manufactured to the exact ring gap, radial depth, and face profile specifications required by the Bomag engine, maintaining combustion efficiency and preventing oil blow-by.
- Direct Engine Rebuild Fitment — this piston ring set seats into the existing piston grooves without rework or machining, streamlining engine overhaul on compatible machines.
- Broad Equipment Coverage — fits an extensive range of Bomag equipment including BF-series pavers, BW single drum, tandem, and pneumatic tyred rollers, and BM-series cold milling machines such as the BW 213 D-40, BW 219 DH-5, BF 691 P-HSE, and BM 600/15 EU-Flex.
- Restored Engine Compression — worn or broken rings cause power loss, excessive oil consumption, and hard starting; replacing this set restores the sealing interface between piston and cylinder bore, returning the engine to full operating output.
- Genuine Bomag Part — sourced directly through the OEM supply chain as part number 05717920, eliminating fitment uncertainty and ensuring the correct part reaches your rebuild.
Piston rings form the critical seal between the piston and the cylinder wall inside the engine. They serve two functions: holding combustion pressure above the piston so the engine generates power, and scraping excess oil from the cylinder wall to prevent it from entering the combustion chamber. When rings wear, lose tension, or break, the engine loses compression, burns oil, produces blue exhaust smoke, and delivers reduced output — all symptoms that worsen with continued operation. Replacing the piston ring set during an engine overhaul restores this seal and is a foundational step in returning any of the compatible Bomag machines to full working condition.
