The Bomag 05724169 Piston is a genuine OEM component designed for the BW 90 S walk-behind light roller. Sourced directly from Bomag, this piston is manufactured to the exact dimensions and material specifications of the original part, ensuring a correct fit in the engine assembly. This piston is the right choice when your BW 90 S requires a dependable, like-for-like engine rebuild component backed by OEM engineering.
Key Features
- OEM-Matched Dimensional Tolerances — manufactured to Bomag's exact bore diameter, compression height, and ring groove specifications, ensuring correct combustion chamber geometry on the BW 90 S engine
- Direct Engine Replacement — installs into the existing cylinder bore without alteration, maintaining the original stroke and compression ratio of the engine assembly
- Confirmed Fitment for the BW 90 S — validated for BW 90 S walk-behind light rollers; reference part number 05724169 when ordering to ensure a match
- Engine Power Restored — a worn or damaged piston causes loss of compression, rough running, and excessive oil consumption; replacing it with this OEM component brings the engine back to its original output
- Genuine Bomag Quality — produced under Bomag's OEM standards using materials selected for the thermal and mechanical demands of a compaction engine operating under continuous vibration loads
The piston is the reciprocating component at the heart of the engine, converting the force of combustion into the crankshaft rotation that powers the machine. It must form a precise seal against the cylinder wall to maintain compression and control oil consumption, and it transfers heat away from the combustion chamber through contact with the cylinder bore. When a piston becomes worn, scored, or cracked, the engine loses compression and efficiency — symptoms include hard starting, increased fuel consumption, and visible oil burning — making timely replacement essential to keeping the BW 90 S performing at full compaction capacity.
