The Bomag 05720380 Piston Ring Set is a genuine OEM component designed for BPR 65/70 D, BPR 75/60 D-3, BPR 75/60 HD-3, and BPR 70/70 D reversible vibratory plates. Sourced directly from Bomag, this piston ring set meets the exact dimensional and material specifications of the original equipment, ensuring a true OEM-grade repair every time. This set covers all four of the compatible BPR-series reversible vibratory plate models, making it the correct choice when rebuilding or overhauling the engine on any of these machines. Order with confidence knowing part number 05720380 matches the original engineering drawings for your Bomag equipment.
Key Features
- OEM-Matched Ring Geometry — Each ring in this set is manufactured to the original bore diameter, width, and gap tolerances specified for the diesel engine in these BPR reversible vibratory plates, ensuring consistent compression and oil control from the first run.
- Complete Set for a Full Engine Rebuild — Includes all rings required for a complete piston ring replacement, so technicians have everything needed for a thorough overhaul without sourcing individual components separately.
- Direct OEM Replacement — This piston ring set installs directly into the engine as a factory-equivalent part, with no reworking of the piston or cylinder bore required beyond standard engine rebuild procedures.
- Broad BPR-Series Coverage — Fits the BPR 65/70 D, BPR 75/60 D-3, BPR 75/60 HD-3, and BPR 70/70 D reversible vibratory plates, covering multiple models in the Bomag diesel-powered reversible plate lineup.
- Restored Compression and Engine Efficiency — Worn or broken piston rings allow combustion gases to bypass the piston, robbing the engine of power and increasing oil consumption. Installing a fresh set restores proper compression, bringing engine performance back to operating spec.
Piston rings form the critical seal between the piston and the cylinder wall inside the engine. They perform three jobs simultaneously: sealing combustion gases above the piston to maximize power output, managing the thin film of oil that lubricates the cylinder wall, and transferring heat away from the piston into the cylinder. When the rings wear, stick, or break, compression drops, oil burns off faster than it should, and the engine loses the power needed to drive the exciter mechanism in a reversible vibratory plate. Replacing the piston ring set during an engine overhaul is a fundamental step in restoring full compaction performance to the machine.
