The Bomag 05748641 Piston Ring Set is a genuine OEM component designed for BPR 25/45-3 reversible vibratory plates and BP 20/50 and BP 25/50 vibratory plates, as well as the BVP 18/45 vibratory plate. Sourced directly from Bomag, this piston ring set delivers an exact match to the original engine specification, ensuring proper sealing and combustion efficiency. This set is a direct replacement for worn or damaged rings, restoring the engine to full operating condition without the need for custom fitting or modification.
Key Features
- OEM Combustion Seal Integrity — Manufactured to Bomag's original engine tolerances, this piston ring set maintains the precise cylinder-wall contact and gas-sealing performance the engine was designed to deliver.
- Exact-Match Replacement — Engineered to match the original ring dimensions and material grade, this set installs directly into the engine bore with no sizing adjustments required.
- 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 forward vibratory plates, making it a versatile service part across multiple Bomag plate compactor models.
- Restored Engine Compression — Fresh piston rings re-establish full compression across the cylinder, recovering lost power output and ensuring the engine runs at the fuel efficiency and compaction force the machine was rated for.
- Reduced Oil Consumption — Properly seated rings prevent oil from entering the combustion chamber, stopping excessive smoke, fouled spark plugs, and the accelerated engine wear that follows oil burn-off.
The piston ring set seals the gap between the piston and the cylinder wall, preventing combustion gases from escaping down into the crankcase and stopping engine oil from being drawn up into the combustion chamber. In a vibratory plate compactor, where the engine runs under sustained load to drive the exciter mechanism, maintaining tight ring-to-wall contact is critical to preserving both power output and fuel economy. When piston rings wear or break, the engine loses compression, oil consumption rises, and the compaction force generated by the plate drops — signs that a ring set replacement is overdue.
