The Bomag 05729395 Piston Ring Set is a genuine OEM component designed for BM 2000/60 and BM 2000/60-2 cold milling machines, MPH 122-2 and MPH 125 recyclers/stabilizers, and the BC 972 RB-2 refuse/landfill compactor. As a factory-sourced assembly, this piston ring set meets the original design specifications required to maintain proper engine compression and oil control in these demanding machines. Sourced directly through the Bomag OEM supply chain, it delivers the exact dimensional tolerances and material grade needed for a correct, lasting installation. Confirm part number 05729395 against your machine's engine specification before ordering to ensure a direct match.
Key Features
- OEM Compression and Oil Control Tolerancing — Genuine Bomag OEM construction ensures each ring in the set meets the precise radial tension and gap specifications required to maintain cylinder seal integrity across high-hour engine operation.
- Complete Set, Direct Engine Fitment — Supplied as a full piston ring set, this component installs directly into the engine cylinder without modification, replacing all compression and oil control rings in a single service event.
- Broad Heavy-Equipment Coverage — Fits BM 2000/60 and BM 2000/60-2 cold milling machines, MPH 122-2 and MPH 125 recyclers/stabilizers, and the BC 972 RB-2 refuse/landfill compactor.
- Restored Engine Compression — Worn or broken piston rings allow combustion gases to bypass the piston, causing power loss, increased oil consumption, and excessive exhaust smoke. A fresh ring set restores proper cylinder pressure and engine output.
- Fuel System Integrity — Correct ring sealing directly affects fuel combustion efficiency; installing the right OEM ring set helps the engine burn fuel cleanly and maintain rated operating power under load.
Piston rings seal the gap between the piston and the cylinder wall, performing two critical jobs: containing the high-pressure combustion gases above the piston to drive the power stroke, and scraping excess oil back down the cylinder bore to prevent oil burning. In heavy-duty applications like cold milling and refuse compaction, where engines run at sustained high loads, rings are subject to significant thermal and mechanical stress. When rings wear, lose tension, or break, compression drops, oil consumption rises, and the engine loses the power needed to drive cutting drums, working tools, or traction systems at full capacity.
