The Bomag 05723078 Cylinder and Piston is a genuine OEM component 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 cylinder and piston assembly delivers the exact tolerances and material specifications required by the original design. It installs as a direct replacement for the factory component, ensuring the engine performs as intended without adaptation. If you are tracing a loss of compression or engine power on your Bomag machine, this is the assembly to address it.
Key Features
- Genuine OEM Compression Integrity — manufactured to Bomag's original bore diameter and piston clearance specifications, ensuring correct compression and combustion chamber geometry for this engine configuration
- Direct Drop-In Assembly — the cylinder and piston are matched as a paired unit, eliminating the guesswork of sourcing and sizing components individually and fitting directly into the engine block
- Broad Bomag Coverage — fits 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, covering multiple machines in the Bomag compact lineup
- Restored Engine Output — a worn or scored cylinder wall leads to blow-by, oil consumption, and loss of drive power; replacing this assembly restores full compression and consistent engine output
- Verified Part Number Fit — order with confidence using Bomag part number 05723078 to confirm you are receiving the correct assembly for your specific machine
The cylinder and piston form the core of the engine's power stroke — the piston travels within the cylinder bore to compress the fuel-air mixture, and the resulting combustion drives the crankshaft. When the cylinder wall becomes worn, scored, or the piston rings lose their seal, compression drops and the engine loses power, runs roughly, or burns oil. Replacing the cylinder and piston as a matched assembly restores the tight tolerances needed for efficient combustion, bringing engine performance back to the level your Bomag roller or trench compactor depends on for effective compaction work.
