The Bomag 05728142 Piston Ring Set is a genuine OEM component designed for a range of Bomag vibratory plates and walk-behind rollers, including the BPR 25/40 D and BP 15/45 D-2. Sourced directly from Bomag, this piston ring set matches the original specifications of the engine installed in these machines, ensuring a proper seal and correct compression from the moment it goes in. This set covers compatible reversible vibratory plates, forward vibratory plates, and the BW 71 E-2 walk-behind roller — making it a versatile service part to stock for fleets running multiple Bomag compaction models.
Key Features
- OEM Compression Integrity — genuine Bomag manufacture ensures each ring delivers the correct compression and oil-control performance for the original engine specification, with no guesswork on tolerancing or material grade
- Direct Engine Replacement — this piston ring set installs as a drop-in replacement for the worn ring pack, restoring cylinder seal without machining or adapting any components
- Broad Bomag Fitment — compatible with the BPR 25/40 D, BPR 30/38 D-2, BPR 30/38 D-3, BP 15/45, BP 15/45 D-2, BP 18/45 D-2, BP 25/48 D, BPR30/38, and BW 71 E-2 across reversible vibratory plates, forward vibratory plates, and walk-behind rollers
- Restored Engine Output — worn or broken piston rings cause blow-by, loss of power, and excessive oil consumption; replacing this set brings compression back to spec and keeps the engine running at full compaction output
- Verified Part Number Fit — ordering by Bomag part number 05728142 confirms you receive the exact ring set engineered for these models, eliminating compatibility risk on a critical engine component
Piston rings seal the gap between the piston and cylinder wall, maintaining combustion pressure while controlling how much oil reaches the combustion chamber. When rings wear, crack, or lose tension, the engine loses compression, burns oil, and produces less power — symptoms that directly reduce the compaction force the machine can deliver. Replacing the piston ring set with a genuine Bomag 05728142 restores the cylinder seal, returning the engine to its designed output and preventing further wear to cylinder bores from uncontrolled blow-by gases.
