The Bomag 05741315 Piston is a genuine OEM component designed for BW 100 AD-4, BW 100 AC-4, BW 120 AD-4, and BW 120 AC-4 tandem rollers. Sourced directly from Bomag, this piston is manufactured to the exact tolerances required to maintain proper compression and engine output in these machines. As a genuine OEM part, it delivers an exact match to the original component — no guesswork on sizing, ring grooves, or pin bore dimensions. If you're overhauling an engine on one of these tandem rollers, part number 05741315 is the correct replacement to specify.
Key Features
- OEM Compression Integrity — Manufactured to Bomag's precise bore and ring groove tolerances, ensuring correct combustion chamber sealing and consistent compression across every power stroke.
- Exact-Match Replacement — Matches the original piston geometry including pin bore diameter, crown profile, and ring land spacing for a direct drop-in installation.
- Broad Tandem Roller Coverage — Fits BW 100 AD-4, BW 100 AC-4, BW 120 AD-4, and BW 120 AC-4 tandem rollers, making it the right choice across the BW 100 and BW 120 series.
- Engine Longevity — A correctly fitted piston prevents blow-by, oil contamination, and power loss — all common consequences of running a worn or improperly sized piston.
- Genuine Bomag OEM Quality — Produced by Bomag to match the original specification, so fit and function are consistent with what came out of the machine at the factory.
The piston is a core reciprocating component inside the engine cylinder, converting the force of combustion into the crankshaft rotation that powers the machine. It works in combination with piston rings and a connecting rod to maintain compression, control oil consumption, and transfer energy efficiently through the drivetrain. When a piston wears, cracks, or is damaged by heat or detonation, the engine loses compression, burns oil, and delivers reduced power — symptoms that directly affect the compaction output and productivity of the roller on the job.
