Automatic belt-tensioner assembly identified by reference 20747516. Volvo-oriented product catalogs confirm the exact belt-tensioner number and include the EC330B excavator among published applications; engine-parts records also document that an earlier number was replaced by 20747516. Four exact owned photographs show the same tensioner body, smooth pulley, bearing and mounting interface. The inherited QSM11 claim was removed because the strongest exact-number catalogs support Volvo applications instead. Confirm 20747516, pulley diameter/width, belt path, arm offset, mounting and engine serial.

Product Type: Automatic belt tensioner assembly
Pulley: Smooth pulley with sealed bearing
Mounting and Offset: Compare with removed tensioner
Belt Path: Verify belt width and routing
