As a genuine OEM part, it matches the original specification precisely, ensuring a correct fit within the engine cylinder bore. This piston is a dependable choice for operators and service technicians looking to restore their Bomag roller to full working condition.
Key Features
- OEM-Grade Compression Integrity — manufactured to Bomag's original material and dimensional specifications, ensuring consistent ring seal and combustion efficiency specific to this engine application
- Direct Engine Replacement — machined to match the original bore diameter and pin geometry, allowing installation without modification to the cylinder assembly
- Confirmed Fitment — fits the BW 142 D-2 single drum roller and the BW 138 AD and BW 135 AD tandem rollers; verify your model before ordering
- Sustained Power Output — a correctly fitted piston maintains the compression ratio the engine was designed to run at, preserving full hydraulic drive output and drum performance across demanding compaction cycles
- Genuine Bomag OEM Part — supplied under Bomag part number 05710064, giving you confidence that this is the same component used in original equipment assembly
The piston is a core reciprocating component inside the engine cylinder, converting combustion pressure into the crankshaft rotation that powers the machine. It works in conjunction with the piston rings and cylinder wall to maintain a tight compression seal, which directly affects fuel efficiency, power delivery, and the ability to drive the roller's vibratory and propulsion systems. When a piston wears, cracks, or loses its ring seal, the engine loses compression, output drops noticeably, and continued operation can cause accelerated damage to surrounding engine components.
