Accessory Drive - Ingenium i4 2.0l Diesel Description and Operation

COMPONENT LOCATION

1. Primary drive belt
2. Coolant pump pulley
3. Generator
4. Air conditioning compressor
5. Idler pulley
6. Idler pulley
7. Crankshaft drive pulley
8. Belt tensioner
9. Idler pulley

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 torsional vibration 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.

CAUTION:

Pulling the pin without using a wrench can damage the belt tensioner and the belt profile.

OPERATION

The crankshaft drive pulley is attached to and rotates with the crankshaft.

The crankshaft drive pulley gives the drive for the primary drive belt which inturn gives rotational power for the front-mounted accessories such as the generator, the air conditioning compressor and the coolant pump.

NOTE:

The crankshaft drive pulley is a combined pulley and torsional vibration damper.
