Accessory Drive - INGENIUM I4 2.0L Diesel: Description

The primary drive belt is a maintenance-free poly-V type belt which is automatically preloaded by the belt tensioner to maintain enough friction around the drive wheels. This ensures slip-free drive of the accessory components.

The crankshaft pulley/mass damper has compressed rubber between its inner and outer diameters to reduce peak levels of torsional vibration inside the crankshaft.

The belt tensioner is calibrated to give the correct amount of tension to the primary drive belt for a particular drive system. Unless a spring inside the assembly of the belt tensioner breaks, or some other mechanical part fails, there is no need to check the tension of the accessory drive belt.

You need to inspect the primary drive belt at every routine service for excessive wear and damage.

The belt tensioner has an idler pulley which is free to rotate on a bearing located at the end of a spring-loaded pivot arm.

The belt tensioner allows you to remove and install the primary drive belt. When you use a wrench to rotate the belt tensioner against its spring to the end stop, two holes align between the arm and the case that allow you to pin the tensioner to the install position. You must only remove the pin when you use the wrench to back off the tensioner.
