The Bomag 05660445 Coupling Hub is a genuine OEM component designed for Bomag BT 50, BT 60, BT 60 G, BT 65, BT 65 G, and BVT 65 tampers. Sourced directly from Bomag, this coupling hub delivers the exact fit and dimensional tolerances required to maintain proper drive engagement on these machines. If your tamper is showing signs of vibration loss, slipping, or irregular ramming stroke, a worn coupling hub is a common culprit — and replacing it with the correct OEM part is the straightforward fix.
Key Features
- Genuine OEM Torque Transfer Integrity — machined to Bomag's original specifications, ensuring the coupling hub transmits drive force cleanly between the engine and exciter mechanism without slip or energy loss
- Direct Drop-In Replacement — engineered to the original mounting interface, this coupling hub installs directly into the tamper drive assembly without rework or modification
- Broad Tamper Compatibility — fits the full range of Bomag tampers including the BT 50, BT 60, BT 60 G, BT 65, BT 65 G, and BVT 65, covering multiple engine and drive configurations
- Restores Full Compaction Performance — a correctly functioning coupling hub keeps the ramming stroke consistent and powerful; a worn or failed hub causes stroke irregularity and reduced compaction output
- OEM Part Number Accuracy — ordering by part number 05660445 confirms you are receiving the exact Bomag-specified component, eliminating guesswork when cross-referencing against the original parts catalog
The coupling hub connects the engine output shaft to the tamper's exciter or drive mechanism, transmitting rotational force to generate the up-and-down ramming action that compacts soil, backfill, and granular materials in trenches and confined areas. It acts as a critical link in the drivetrain — absorbing minor misalignment and shock loads while maintaining consistent power transfer. When the coupling hub wears, cracks, or fails, the tamper loses stroke power, may vibrate unevenly, or stop ramming altogether, halting compaction work until the component is replaced.
