The Bomag 05715755 Piston Ring Set is a genuine OEM component designed for Bomag BW 1050 T, BW 650 T, BW 850 T, BW 850 TR, and BW 85 T trench compactors, as well as the BW 75 AD walk-behind roller. Sourced directly from Bomag, this piston ring set meets the exact specifications of the original equipment, ensuring a correct, direct installation into the engine assembly. It fits the complete engine bore geometry of each covered machine, so you can service with confidence knowing the rings seat and seal the way the engine was designed to run.
Key Features
- Genuine OEM Sealing Precision — manufactured to Bomag's exact ring profile and material hardness specifications, ensuring correct compression and oil control characteristics for the engine in this application.
- Direct Engine Replacement — this piston ring set installs into the engine cylinder bore as a direct match to the original, with no fitting or modification needed to achieve proper ring end-gap alignment.
- Broad Fitment Coverage — compatible with the BW 1050 T, BW 650 T, BW 850 T, BW 850 TR, and BW 85 T trench compactors, as well as the BW 75 AD walk-behind roller.
- Engine Compression Restored — worn or broken piston rings cause loss of compression, increased oil consumption, and hard starting; replacing them with part number 05715755 restores the engine's ability to develop full power output.
- Fuel System Integrity — correct ring sealing prevents combustion gases from bypassing the piston, protecting the crankcase from contamination and maintaining efficient fuel combustion across the machine's operating load range.
A piston ring set creates a dynamic gas-tight seal between the piston and the cylinder wall, allowing the engine to build the compression pressure needed for combustion while controlling oil migration from the crankcase into the combustion chamber. In compaction equipment like trench compactors and walk-behind rollers, engines operate under sustained load, which accelerates ring wear over time. When rings lose their sealing effectiveness, the engine suffers from blow-by, excessive oil consumption, blue exhaust smoke, and a loss of the power needed to drive the compaction mechanism — signs that a ring set service is overdue.
