The Bomag 05744837 Piston with Piston Rings is a genuine OEM component designed for the BP 18/45 D-2 vibratory plate, BPR 30/38 D-3 reversible vibratory plate, and BT 80 D tamper. Sourced directly from Bomag, this piston assembly delivers the exact dimensions, ring groove tolerances, and material grade specified for these engines — no guesswork on fitment. Whether you are rebuilding a diesel engine on a plate compactor or a tamper, part number 05744837 restores the combustion chamber to OEM specification and gets your machine back to work.
Key Features
- OEM Combustion Precision — genuine Bomag manufacture ensures correct piston diameter, compression height, and ring-groove geometry for consistent combustion performance in diesel-powered compaction equipment
- Complete Piston Assembly — supplied with piston rings included, so the engine can be reassembled in a single service step without sourcing rings separately
- Confirmed Fitment — engineered to fit the BP 18/45 D-2 vibratory plate, BPR 30/38 D-3 reversible vibratory plate, and BT 80 D tamper; verify your model before ordering
- Restored Compression and Power — worn or damaged pistons cause loss of compression, hard starting, and reduced compaction force; replacing with this assembly brings output back to rated levels
- Fuel System Integrity — properly seated piston rings maintain the combustion seal that prevents blow-by, protecting the crankcase and reducing oil contamination in diesel-fueled units
The piston is the reciprocating heart of a diesel engine, converting combustion pressure into the mechanical force that drives compaction. The piston rings seal the combustion chamber against the cylinder wall, maintaining compression and preventing oil from entering the combustion zone. When a piston or its rings wear, compression drops, the engine loses power, oil consumption rises, and — in plate compactors and tampers especially — compaction output falls well below the rated force the machine is designed to deliver. Replacing the assembly with a correct OEM piston and ring set restores the engine's combustion efficiency and returns the machine to full working capacity.
