The Bomag 05713463 Piston is a genuine OEM replacement built for Bomag tandem rollers including the BW 138 AD, BW 138 AC, BW 135 AD, BW 135 AC, BW 120 AD-3, BW 120 AC-3, BW 125 ADH, BW 125 ACH, BW 100 AD-3, BW 100 AC-3, BW120AD 3, and BW 138-AD. Sourced directly from Bomag, this piston is manufactured to the same specifications as the original, ensuring a correct fit within the engine assembly. This component is an authoritative choice for operators and technicians who need dependable engine performance restored without compromise.
Key Features
- Genuine OEM Engine Tolerances — manufactured to Bomag's exact bore diameter, ring groove dimensions, and compression height specifications, ensuring proper combustion sealing for this piston's specific engine application.
- Direct Drop-In Replacement — engineered to match the original mounting configuration and pin bore dimensions, allowing straightforward installation within the existing engine block of compatible tandem rollers.
- Broad Tandem Roller Coverage — fits Bomag BW 100, BW 120, BW 125, BW 135, and BW 138 series tandem rollers across AC and AD variants, including the BW 100 AC-3, BW 100 AD-3, BW 120 AC-3, BW 120 AD-3, BW 125 ACH, BW 125 ADH, BW 135 AC, BW 135 AD, BW 138 AC, BW 138 AD, BW120AD 3, and BW 138-AD.
- Sustained Compression and Power Output — a correctly fitted piston maintains the engine's compression ratio and thermal efficiency, keeping the roller delivering consistent drum force across asphalt passes; a worn or damaged piston leads to power loss, excessive oil consumption, and rough running.
- Verified Part Number Traceability — ordering by Bomag part number 05713463 confirms you are receiving the correct piston for your specific machine variant, eliminating the risk of selecting an incompatible size or configuration.
The piston is a core reciprocating component inside the engine cylinder, converting combustion pressure into the crankshaft rotation that powers the machine. It must maintain a precise fit within the cylinder bore to preserve compression, control oil consumption, and transfer heat efficiently to the cylinder walls. When a piston wears, cracks, or sustains damage from overheating or detonation, the engine loses compression, oil burns off, and performance degrades — making timely replacement with a correctly specified part essential to keeping the tandem roller productive on the job.
