9. Set the tensioner as per the recommended tension for a new belt using a belt frequency meter (new belt: 106-118 Hz).
If the tension is within the recommended guidelines, then the mark on the arm should align close to the lower mark on the
housing as shown below.
NOTE: Belt tension frequency measurement should be the primary method used to determine correct belt tension. The
markings on the tensioner arm and housing exist to provide a rough visual reference of the belt tension.
If the belt tension frequency measurement is not within recommended guidelines, the sliding idler pulley position can be
adjusted to increase/decrease belt tension.
NOTE 1
The sliding idler pulley position is set during factory production for correct belt tension. If required, its position can be
adjusted in the field to achieve the required tension.
The setting measurement for the sliding idler is taken as follows:
Measure from the face of the sliding idler plate to the edge of the frame as indicated in the image below:
The distances given below are nominal starting points and the exact location will depend on the variation of the drive system
layout.
