The Bomag 05744885 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 a drop-in installation without guesswork or adaptation. This part is the correct service replacement for the diesel-powered BPR-series reversible vibratory plates covered in the fitment data, giving technicians and operators confidence that they are ordering the right component the first time.
Key Features
- Genuine OEM Compression and Oil Control Rings — manufactured to Bomag's exact ring gap, tension, and material specs for the diesel engine powering these reversible plates, ensuring consistent compression and oil film control from the first startup after installation.
- Direct-Fit Replacement — engineered to match the original bore diameter and ring profile, so this set installs straight into the cylinder without machining or modification.
- Confirmed Fitment — compatible with BPR 45/55 D and BPR 55/65 D reversible vibratory plates, covering both force classes in the diesel BPR series.
- Restored Engine Compression — worn or broken piston rings cause loss of cylinder pressure, increased oil consumption, and rough running; replacing the full set restores proper power output and engine efficiency.
- Fuel System Integrity — correct ring sealing prevents blow-by gases from contaminating the crankcase oil, protecting downstream engine components and extending service intervals.
A piston ring set seals the combustion chamber between the piston and the cylinder wall, maintaining the compression needed for efficient fuel ignition while also controlling the thin layer of oil that lubricates the cylinder bore. The rings work in a high-heat, high-pressure environment and wear gradually over time, leading to reduced compression, increased oil consumption, excessive smoke, and a noticeable drop in engine power. Replacing the full set — rather than individual rings — restores proper sealing across all ring grooves and ensures even wear from the start of the new service life.
