Adjust Rotor Drive Belt Tension
There will normally be a rapid drop in tension during the run-in period for new belts.
When new belts are fitted, check the tension every 2 - 3 hours and adjust until the
tension remains constant.
Too much tension shortens belt and bearing life.
Too little tension will cause poor performance, especially in respect of no-stress
devices.
Belt failures due to lack of correct tensioning will not be covered under your
Timberwolf warranty.
1.
Remove the engine bay side panel.
Figure 25 - Tensioner Pulley Assembly

3.
Turn the nut on the end of the tensioner pulley
slider until the correct belt tension is achieved
(Figure 25, Item 2). (Refer to Section 5.11 "
