The Bomag 05815101 Piston Kit is a genuine OEM component designed for a wide range of Bomag single drum rollers, tandem rollers, cold milling machines, and pavers. Sourced directly from Bomag, this piston kit delivers the exact fitment and dimensional accuracy required to restore engine performance across compatible equipment. This kit is confirmed to fit models including the BW 177 D-3, BW 177 D-4, BW 177 D-5, BW 145 D-3, BW 141 AD-2, BW 151 AD-2, BM 500/15, BM 600/15, and BF 800 P S500, among others. When your equipment is due for an engine rebuild or piston replacement, part number 05815101 provides the correct OEM-grade components to get the job done right.
Key Features
- Genuine OEM Piston Tolerancing — manufactured to Bomag's original bore diameter and ring groove specifications, ensuring correct compression and proper sealing within the cylinder
- Drop-In Engine Rebuild Fit — engineered to match the original piston assembly configuration, so this kit installs directly without machining or custom fitting
- Broad Bomag Fleet Coverage — fits BW 177, BW 145, BW 141, and BW 151 series rollers, BM 500/15 and BM 600/15 cold milling machines, and the BF 800 P S500 paver, including EU-Flex and T4i variants
- Compression and Power Restoration — a worn or damaged piston causes loss of compression, increased oil consumption, and rough running; this kit restores correct combustion chamber integrity and consistent engine output
- Fuel System Integrity — correct piston fit maintains proper air-fuel combustion ratios, supporting efficient fuel use and reducing the risk of unburned fuel contaminating engine oil
The piston is a core reciprocating component inside the engine cylinder, responsible for compressing the air-fuel mixture and transferring combustion force to the crankshaft via the connecting rod. A correctly fitted piston maintains the compression seal needed for efficient power output and reliable engine operation. When a piston wears, scores, or the rings lose their seal, the engine loses compression, burns oil, and can suffer serious internal damage if left unaddressed — making timely replacement with a quality piston kit essential to keeping the engine running at full capacity.
