The Bomag 05747397 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 25/48, BP 23/48, BP 23/60, BP 20/60, 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. As a genuine Bomag part, this piston ring set is manufactured to the exact tolerances required by the original engine specification, ensuring a correct, trouble-free installation. Sourced directly through authorized Bomag supply channels, part number 05747397 is the right choice when rebuilding or overhauling the engine in your Bomag compaction equipment.
Key Features
- OEM-Grade Ring Tolerancing — manufactured to Bomag's exact cylinder bore and compression specifications, delivering the sealing performance the original engine was designed around
- Drop-In Engine Compatibility — this piston ring set installs directly into the engine bore without modification, maintaining correct ring gap and tension on each supported model
- Broad Vibratory Plate Coverage — fits a wide range of Bomag forward vibratory plates (including BP 20/48, BP 25/48, and BP 23/60) and reversible vibratory plates (including BPR 25/40, BPR 30/38-3, and BPR 35/38-3)
- Compression and Oil Control — a correctly seated ring set restores full compression and prevents oil blow-by, keeping the engine running at rated power output for effective plate compaction
- Genuine Bomag Part — part number 05747397 is sourced through authorized Bomag supply channels, ensuring the component matches the original design intent without substitution or compromise
The piston ring set sits in machined grooves around the piston and forms a dynamic seal between the piston and the cylinder wall. The rings serve two functions: compression rings trap combustion gases above the piston to maximize power output, while the oil control ring scrapes excess oil from the cylinder wall to prevent burning. When rings wear, crack, or lose tension, compression drops, oil consumption rises, and the engine loses the power needed to drive the exciter mechanism that produces compaction force. Replacing the ring set with a genuine Bomag piston ring set restores proper sealing, returning the plate to full operating performance.
