The Bomag 05715849 Piston is a genuine OEM component designed for Bomag BW 100, BW 120, BW 124, BW 125, BW 135, BW 138, and C 815 series tandem rollers and single drum rollers. As a direct OEM replacement, this piston is manufactured to the same tolerances and material specifications as the original, ensuring a correct fit within the engine or hydraulic assembly it serves. This part is confirmed compatible with a wide range of Bomag roller configurations, including BW 100 AC-3, BW 100 AD-3, BW 120 AC-3, BW 120 AD-3, BW 124 DH-3, BW 124 DH-4, BW 124 PDH, BW 124 PDH-3, BW 124 PDH-40, BW 125 ADH, BW 135 AD, BW 138 AC, BW 138 AD, C 815 C, and C815D rollers. Sourcing the correct OEM piston protects the integrity of the assembly and keeps your machine performing as intended.
Key Features
- OEM-Matched Dimensional Tolerances — manufactured to the exact bore diameter, ring groove depth, and compression height of the original, ensuring proper sealing and combustion or hydraulic efficiency for this piston application.
- Drop-In Replacement — engineered to align with the original connecting rod, pin bore, and cylinder bore dimensions for a straightforward installation without reworking the assembly.
- Broad Roller Coverage — fits BW 100, BW 120, BW 124, BW 125, BW 135, BW 138, and C 815 series tandem rollers and single drum rollers, including BW 124 DH-3, BW 124 PDH-3, BW 138 AC, BW 138 AD, and additional variants.
- Sustained Power Output — a correctly fitted piston maintains compression and consistent power delivery; a worn or failed piston leads to loss of compression, increased oil consumption, and degraded machine performance.
- Genuine Bomag OEM Quality — supplied as an authentic Bomag part under part number 05715849, backed by Bomag's OEM standards for material grade and dimensional consistency.
A piston is a core reciprocating component within an engine or hydraulic cylinder, converting pressure — whether from combustion gases or hydraulic fluid — into mechanical force that drives the machine. It must maintain a precise seal against the cylinder wall through its rings, and any wear, scoring, or dimensional deviation leads directly to compression loss, reduced output power, and potential damage to surrounding components such as cylinder liners and connecting rods. Replacing a worn piston with a correctly specified OEM part restores proper compression, protects the rest of the assembly, and returns the roller to full working capacity.
