The Bomag 05720146 Piston Ring Set is a genuine OEM component designed for the BW 71 EHB-2 walk-behind roller and BPR 50/55 D and BPR 60/65 D reversible vibratory plates. Sourced directly from Bomag, this piston ring set matches the exact dimensions and material grade of the original rings installed at the factory, ensuring a correct seal without rework or shimming. This set is the dependable choice when engine compression has dropped or an overhaul is underway on any of the covered machines.
Key Features
- OEM Compression Integrity — genuine Bomag rings are manufactured to the precise dimensional tolerances and surface finish required for correct cylinder-wall sealing on these small-displacement engines
- Complete Set, Ready to Install — the full ring set installs directly onto the piston, covering compression and oil-control rings so no separate sourcing is needed to complete the job
- Confirmed Fitment — engineered for the BW 71 EHB-2 walk-behind roller and the BPR 50/55 D and BPR 60/65 D reversible vibratory plates; verify your model before ordering
- Restored Engine Performance — correctly seated rings maintain cylinder compression, support proper oil control, and allow the engine to deliver full power output to the compaction mechanism
- Overhaul-Ready Quality — using genuine OEM rings during a top-end rebuild protects the investment in new pistons, bores, and gaskets by ensuring every mating surface is held to spec
Piston rings form the dynamic seal between the piston and the cylinder wall inside the engine. They serve two critical functions: holding combustion pressure above the piston so the engine generates full power, and scraping excess oil off the cylinder wall to prevent it from burning in the combustion chamber. When rings wear, become stuck with carbon deposits, or break, compression drops, oil consumption rises, and the engine loses the power needed to drive the compaction system effectively. Replacing the full ring set during any top-end service restores cylinder sealing and brings the engine back to its correct operating condition.
