The Bomag 05745437 Piston Ring Set is a genuine OEM component designed for BPR 45/55 D and BPR 55/65 D reversible vibratory plates. Sourced directly from Bomag, this piston ring set delivers an exact match to the original specification, ensuring proper cylinder sealing and engine performance on your machine. This set is the correct replacement when rings show signs of wear, blow-by, or oil consumption that signals it is time for an engine rebuild or top-end service.
Key Features
- OEM Cylinder Sealing Integrity — Manufactured to Bomag's original compression and oil-control ring specifications, preserving the combustion efficiency your engine was built to deliver.
- Direct Engine Replacement — Engineered to drop into the original bore without modification, matching the correct ring gap, groove width, and radial thickness of the factory set.
- Confirmed Fitment — Compatible with BPR 45/55 D and BPR 55/65 D diesel reversible vibratory plates, covering both common plate sizes in this Bomag series.
- Restored Compression and Power — Worn or broken piston rings allow combustion gases to bypass the piston, robbing the engine of power and increasing oil consumption; a fresh set restores full cylinder pressure and smooth operation.
- Complete Set Convenience — Supplied as a matched set so all rings are replaced together in a single service event, maintaining consistent ring tension and sealing across the entire piston.
Piston rings form a dynamic seal between the piston and the cylinder wall, controlling combustion pressure above the piston while regulating the thin oil film below it. When rings wear, crack, or lose tension, combustion gases escape past the piston — a condition known as blow-by — leading to reduced engine power, increased oil consumption, and exhaust smoke. Replacing the piston ring set as part of a top-end or full engine rebuild restores compression to specification and returns the reversible vibratory plate to its rated compaction performance.
