A single seven ribbed belt drives all the engine
mounted accessories. The torsional vibration
damper on the front of the crankshaft drives the
belt. An automatic tensioner, located on the left
accessory mounting bracket, keeps the belt at
the correct tension. An idler pulley on the right
accessory mounting bracket increases the wrap
angle around the generator pulley.
The torsional vibration damper incorporates
compressed rubber between its inner and outer
diameters to absorb vibration and shock loads.
The automatic tensioner consists of an idler
pulley on the end of a spring loaded pivot arm.
The pivot arm can be turned counter-clockwise
(viewed from the front of the engine) for removal
and installation of the belt. A belt wear indicator
is incorporated on the rear of the pivot arm.
