The Bomag 05749128 Piston Ring Set is a genuine OEM component designed for Bomag BT 50, BT 60, BT 60 G, BT 65, and BT 65 G tampers. Sourced directly from Bomag, this piston ring set meets the original engineering specifications for these machines, ensuring a correct, confident installation. This is a direct OEM replacement that fits all five tamper models in the BT series covered by part number 05749128, so you can order with confidence that you are getting the right part the first time.
Key Features
- OEM Compression Sealing Integrity — manufactured to Bomag's original ring geometry, gap tolerances, and material grade, so combustion sealing performance matches what left the factory
- Drop-In Engine Replacement — designed to seat correctly in the piston grooves of the BT-series engine without any machining or modification to the bore or piston
- Broad BT-Series Coverage — fits BT 50, BT 60, BT 60 G, BT 65, and BT 65 G tampers, consolidating ring replacement across the full range of these Bomag rammers under one part number
- Restored Power and Starting Performance — worn or broken piston rings cause compression loss, hard starting, excessive oil consumption, and sluggish ram action; a fresh ring set brings combustion pressure back to spec
- Fuel System and Emissions Protection — correct ring seal prevents blow-by gases from contaminating the crankcase oil and keeps exhaust output within normal operating limits for continued safe use on site
Piston rings form a dynamic seal between the piston and the cylinder wall, maintaining the compression pressure needed for reliable ignition and full power output in the tamper's engine. They also control oil consumption by scraping excess lubricant off the cylinder wall and returning it to the sump. When rings wear, lose tension, or break, compression drops — leading to difficult cold starts, a noticeable loss of impact force at the shoe, and increased oil burning. Replacing the full ring set with a genuine Bomag piston ring set restores proper cylinder sealing and returns the tamper to its rated compaction performance.
