The Bomag 05749129 Piston is a genuine OEM component designed for Bomag BT 50, BT 60, BT 60 G, BT 65, and BT 65 G tampers. Sourced directly from Bomag, this piston meets the original engineering specifications for these machines, ensuring a correct, dependable installation every time. Whether you are rebuilding a well-used tamper or restoring one after a failure, this is the factory-authorized part for the job.
Key Features
- Genuine OEM Precision — manufactured to Bomag's original dimensional and material specifications, so this piston delivers the compression characteristics your tamper was engineered around
- Direct-Fit Replacement — machined to the exact bore diameter and ring-groove profile of the original, allowing straightforward installation without modification
- Broad Tamper Coverage — fits the BT 50, BT 60, BT 60 G, BT 65, and BT 65 G tampers, making it a practical stock item for fleets running multiple Bomag rammer models
- Restored Compaction Power — a worn or scored piston reduces compression and weakens impact force; replacing it with part number 05749129 restores full stroke energy and compaction performance
- Engine Integrity Protected — correct ring seal and piston-to-wall clearance prevent oil blow-by and overheating, protecting the surrounding engine components from accelerated wear
The piston is the reciprocating heart of a tamper's two-stroke or four-stroke engine, converting combustion pressure into the downward mechanical force that drives the rammer's jumping action. It travels at high speed inside the cylinder bore, and its ring seals maintain compression while controlling oil consumption. When a piston becomes worn, cracked, or scored — whether from heat, debris ingestion, or hours of heavy use — compression drops sharply, the machine loses impact energy, and continued operation risks cylinder wall damage or a full engine seizure. Replacing the piston promptly with a correctly specified part keeps the engine running at its designed output and protects the more costly components around it.
