SETTING BELT TENSION
1. Proper setting of the belt tension requires a belt tension checker (part number
TEN011452).
2. Measure the belt span.
3. On the belt tension checker, position the o-ring on the span scale at the measured
belt span.
4. Position the o-ring on the deflection force scale to zero.
5. Place a straight edge across the outside diameters of the motor pulley and
compressor flywheel.
6. Place the tension checker squarely on one belt at the center of the belt span. Apply
a force on the plunger, perpendicular to the belt span until the bottom of the large
o-ring is even with the bottom of the straight edge.
7. Remove the tension checker and read the force applied from the bottom of the
small o-ring on the deflection force scale.
8. Compare the force you have applied with the values given in the table on page 25.
The force should be between the minimum (used belt) and maximum (new belt)
shown.
9. Make adjustments to the location of the motor to achieve proper tension.
