The Bomag 05748782 Piston Ring Set is a genuine OEM component designed for the BW 900-50 walk-behind roller. Sourced directly from Bomag, this piston ring set delivers the exact material grade, ring gap tolerances, and dimensional specifications required for correct sealing and compression in the engine. This set is the correct direct replacement for the BW 900-50, ensuring the engine performs to its original output without modification or improvised fitment.
Key Features
- OEM Compression Sealing Integrity — genuine Bomag manufacture ensures each ring meets the precise radial tension and gap spec required to maintain cylinder compression in the BW 900-50 engine
- Exact Dimensional Match — rings are sized to the original bore diameter and groove depth, installing directly into the piston without reworking or fitting adjustments
- Confirmed Fitment — engineered specifically for the BW 900-50 walk-behind roller; part number 05748782 is verified against Bomag's OEM catalog for this machine
- Restored Engine Output — worn or broken piston rings cause blow-by, oil burning, and loss of power; replacing them with this set restores compression and keeps the engine running at its rated compaction output
- Complete Set — supplied as a full piston ring set so all rings are renewed together, preventing mismatched wear between new and old rings in the same bore
Piston rings seal the combustion chamber between the piston and the cylinder wall, maintaining the compression pressure needed for the engine to fire and produce power. They also control oil consumption by scraping excess oil from the cylinder wall and returning it to the sump. When piston rings wear, crack, or lose tension, compression drops, fuel efficiency suffers, the engine may begin burning oil, and the machine loses the consistent power output needed for effective compaction work.
