Bentley Continental GT GTC Flying Spur W12 Ribbed Drive Belt Tensioner 07D903315J

Ribbed Drive Belt Tensioner for Bentley W12

Restore stable accessory-belt tension with a replacement tensioner assembly for Bentley Continental GT, Continental GTC and Flying Spur W12 models. Reference part number 07D903315J, the unit combines the spring-loaded tensioner body, pulley and damping mechanism in one service assembly.

Consistent Belt Control

The tensioner keeps the auxiliary ribbed belt correctly loaded as engine speed changes. Wear in the pulley bearing, pivot or damper can cause belt noise, vibration, unstable tracking or reduced accessory-drive reliability. Replacing the complete assembly helps restore smooth belt operation.
