Variator belt tension

Check the tension of the variator drive belt occasionally.
When correctly tensioned, it should be possible to press in the belt by thumb 20 mm (3/4") as shown in fig.1. The tension is checked first when the belt has been run for a short time after the adjustment.

The belt is tightened by loosening each nut on the screws A in fig.1, the same amount; the screws are by that turned counter-clockwise. The lower nut is slackened from inside the cab through an opening on the right-hand heater and defroster control. Do not adjust the nuts in fig 2. These are properly adjusted when the variator is installed and their adjustment must not be altered when the belt is tensioned.
