The Bomag 05722207 Piston Ring Set is a genuine OEM component designed for the BP 20/48 D and BP 23/48 D vibratory plates, the BPR 30/38 D reversible vibratory plate, and the BW 71 E walk-behind roller. Sourced directly from Bomag, this piston ring set delivers an exact match to the original engine specification, ensuring the sealing geometry and ring tension are correct for the application. Confirmed fitment across all four models means you can order with confidence — part number 05722207 is the right set for these machines.
Key Features
- OEM Sealing Precision — manufactured to the same compression and oil-control ring tolerances as the original, maintaining proper cylinder sealing pressure across the engine's operating range
- Direct Engine Drop-In — rings are pre-sized to the correct bore diameter and profile for these Bomag engines, fitting straight into the existing cylinder without modification
- Broad Model Coverage — fits the BP 20/48 D and BP 23/48 D vibratory plates, the BPR 30/38 D reversible vibratory plate, and the BW 71 E walk-behind roller
- Compression Restoration — worn or broken piston rings allow combustion gases to bypass the piston, sapping power and increasing oil consumption; a fresh set restores full engine output and efficiency
- Genuine Bomag Part — supplied as an authentic OEM assembly under part number 05722207, backed by Bomag's quality standards for compaction equipment
Piston rings form the dynamic seal between the piston and the cylinder wall, controlling combustion pressure above the piston and regulating the thin oil film below it. Compression rings hold the high-pressure combustion gases in the chamber so the engine delivers full power to the compaction mechanism, while oil control rings scrape excess lubricant back down the cylinder bore to prevent burning. When rings wear, crack, or lose tension, the engine loses compression, burns oil, runs unevenly, and can eventually fail to generate enough force to drive the vibration system effectively — making timely replacement critical to keeping the plate or roller working at rated output.
