The Bomag 05748643 Piston Ring Set is a genuine OEM component designed for Bomag BPR 25/45-3 reversible vibratory plates and BP 20/50, BP 25/50, and BVP 18/45 vibratory plates. Sourced directly from Bomag, this piston ring set delivers the precise tolerances and material grade required to maintain proper compression and oil control in the engine. This set is a direct, spec-matched replacement that installs exactly as the original, keeping your compaction equipment running at full power.
Key Features
- OEM-Grade Compression Sealing — manufactured to Bomag's exact ring gap tolerances and material specifications, ensuring consistent combustion chamber sealing and controlled oil consumption for the engine in this application
- Direct Replacement Fit — matches the original ring dimensions and groove profile for straightforward installation without modification to the piston or cylinder bore
- Broad Vibratory Plate Coverage — fits the BPR 25/45-3 reversible vibratory plate and the BP 20/50, BP 25/50, and BVP 18/45 vibratory plates, making part number 05748643 a practical stock item for mixed-fleet operators
- Restored Engine Output — worn or broken piston rings cause loss of compression, increased oil burning, and reduced centrifugal force output; replacing them with this set restores rated engine performance and compaction effectiveness
- Genuine Bomag OEM Part — supplied as an authentic Bomag assembly, not a generic substitute, so you get the correct ring count, profile, and material grade for this engine family in one kit
A piston ring set seals the gap between the piston and the cylinder wall, serving two critical functions: maintaining combustion pressure so the engine produces its rated power, and controlling oil so it does not enter the combustion chamber and burn off. In a vibratory plate compactor, a healthy engine is what drives the exciter mechanism that generates compaction force — so degraded ring sealing translates directly into weaker plate performance and higher fuel consumption. When rings wear, crack, or lose tension, operators will notice harder starting, blue exhaust smoke, and a noticeable drop in plate compaction output, all of which signal it is time to fit a fresh ring set.
