The Bomag 05723212 Piston is a genuine OEM piston designed for Bomag BW 65 HS, BW 65 S, and BW 75 E walk-behind light rollers, as well as BW 35 and BW 35 W trench compactors. Sourced directly from Bomag, this piston delivers the exact dimensions and material specification required for a correct installation with no guesswork on fitment. As a genuine OEM component, it meets Bomag's original engineering standards, ensuring the engine performs the way it was built to. If your machine is showing signs of compression loss, excessive oil consumption, or reduced power output, replacing this piston with part number 05723212 is the right call.
Key Features
- OEM Compression Integrity — manufactured to Bomag's original bore diameter and ring-groove tolerances, ensuring correct cylinder sealing and combustion efficiency for this engine application
- Direct-Fit Replacement — matches the original piston geometry and pin bore dimensions, dropping straight into the cylinder bore without machining or adaptation
- Broad Fitment Coverage — fits BW 65 HS, BW 65 S, and BW 75 E walk-behind light rollers, plus BW 35 and BW 35 W trench compactors
- Restores Engine Power — a worn or damaged piston causes compression drop, hard starting, and loss of compaction performance; this replacement brings output back to spec
- Fuel and Oil Efficiency — proper piston fit prevents blow-by and oil migration past the rings, keeping fuel consumption and oil loss in check during operation
The piston is the reciprocating component inside the engine cylinder that converts the force of combustion into crankshaft rotation, powering the machine's drive and vibration systems. It works in direct contact with the cylinder wall and piston rings, so dimensional accuracy is critical — even minor wear leads to compression loss, increased oil burn, and sluggish engine response. When a piston fails or wears beyond tolerance, the engine loses the mechanical efficiency needed to drive compaction output, making timely replacement essential to keeping the machine productive.
