The Bomag 05744212 Piston Ring Set is a genuine OEM component designed for the BPR 40/45 D, BPR 40/45 D-2, and BPR 40/45 D-3 reversible vibratory plates. Sourced directly from Bomag, this piston ring set delivers the correct dimensions, material grade, and ring geometry to match the original engine specification on these machines. This set fits all three variants of the BPR 40/45 D series, making it the straightforward choice when servicing the engine on any of these reversible vibratory plates. Order with confidence using part number 05744212 to ensure you receive the exact replacement your machine requires.
Key Features
- OEM Ring Geometry and Material Grade — manufactured to the same compression and oil-control ring profiles as the original, ensuring proper cylinder sealing across the full engine operating range
- Complete Set for a Full Engine Service — includes all rings needed for a single piston rebuild, so the job is done correctly without sourcing individual components separately
- Direct-Fit for BPR 40/45 D Series — confirmed compatibility with the BPR 40/45 D, BPR 40/45 D-2, and BPR 40/45 D-3 reversible vibratory plates; installs without modification
- Restores Compression and Engine Efficiency — worn piston rings allow combustion gases to bypass the piston, robbing the engine of power and increasing oil consumption; this replacement set brings compression back to proper levels
- Genuine Bomag OEM Part — part number 05744212 is an authorized Bomag replacement, backed by the manufacturer's original engineering and quality control standards
Piston rings seal the gap between the piston and the cylinder wall, preventing combustion gases from escaping into the crankcase and keeping engine oil out of the combustion chamber. On a diesel-powered reversible vibratory plate like the BPR 40/45 D series, maintaining this seal is critical — the engine must deliver consistent power to drive the exciter mechanism and generate the vibration that compacts the material underfoot. When piston rings wear or break, the engine loses compression, produces excessive smoke, consumes more oil, and eventually loses the power output needed to compact effectively. Replacing the piston ring set at the correct service interval restores engine performance and extends the working life of the machine.
