Accessory Drive - TDV6 3.0L Diesel (G1858865): Overview

The accessory drive is a belt system powered by a pulley attached to the front of the crankshaft. The crankshaft pulley, which incorporates a torsional vibration damper, drives a single drive belt. An automatic belt tensioner maintains the drive belt at the correct tension. Together with idler pulleys, the belt tensioner also guides the drive belt clear of obstructions and sets the correct 'wrap-around' of the accessory component drive pulleys to ensure a slip-free drive.

The belt tensioner consists of an idler pulley on the end of a spring loaded pivot arm. The pivot arm can be turned manually for removal and installation of the drive belt. The belt tensioner is calibrated to automatically maintain the correct tension in the drive belt.
