The Bomag 05747398 Piston Ring Set is a genuine OEM component designed for Bomag vibratory plates and reversible vibratory plates, including the BP 20/48, BP 18/45-2, BP 23/48, BP 25/48, BP 20/60, BP 23/60, BP 15/36-2, BP 15/45-2, BPR 25/40, BPR 25/32, BPR 25/45-3, BPR 30/38, BPR 30/38-2, BPR 30/38-3, and BPR 35/38-3. Sourced directly from Bomag, this piston ring set matches the exact specifications of the original engine component it replaces. Verifying part number 05747398 against your machine's model before ordering ensures a correct, hassle-free installation.
Key Features
- Genuine OEM Engine Sealing Integrity — manufactured to Bomag's exact ring geometry, material grade, and tension specs, ensuring proper compression and oil control for the engine in your vibratory plate
- Direct-Fit Replacement — engineered to install into the existing piston grooves without modification, restoring the engine to its original bore-to-ring clearance
- Broad Vibratory Plate Coverage — fits BP-series vibratory plates including the BP 20/48, BP 25/48, and BP 23/60, as well as BPR-series reversible vibratory plates including the BPR 25/40, BPR 30/38-3, and BPR 25/45-3, among others
- Compression and Oil Control Restored — worn piston rings cause loss of compression, increased oil consumption, and reduced centrifugal force output; replacing this set returns the engine to full operating power
- Complete Set for a Full Engine Rebuild — supplied as a matched set so all rings are renewed together, eliminating the risk of mismatched wear between new and old rings
The piston ring set seals the gap between the piston and the cylinder wall inside the engine, performing two critical jobs: maintaining compression during the combustion stroke and preventing engine oil from entering the combustion chamber. When the rings wear, the engine loses power, burns oil, and produces excess exhaust smoke — all of which directly reduce the compaction output of the vibratory plate. Replacing the full ring set during an engine rebuild restores combustion efficiency, extends cylinder life, and brings the plate back to its rated centrifugal force and performance.
