7. Ensure that the new belt is fitted correctly into the grooves on all pulleys except the tensioner
pulley prior to beginning next step.
8. Slowly pull down on the tensioner bolt with a 17 mm socket wrench and slide the new belt
onto the tensioner pulley until it is correctly fitted into the grooves of the pulley.
9. Slowly release the downward pressure on the wrench to remove it from the tensioner bolt.
The belt should be aligned as shown below.

10. Check the belt tension with Frequency Gauge P/N 2041903. The recommended setting for a
new belt is 106-118 Hz. If the tension is in this range, the mark on the tensioner arm should
align close to the lower mark on the tensioner housing as shown below. If the belt tension
frequency is not in the recommended range, the sliding idler pulley position can be adjusted
to increase/decrease belt tension. See “Fan Drive Belt Adjustment” below.
