CHECK FAN BELT TENSION
8)
An deflection method can be used to check belt
tension by applying 11 kgf (25 lbf) force between
the pulleys on V-belts. If the deflection is more
than one belt thickness per foot of pulley center
distance, the belt tension must be adjusted.
Inspect the fan belt for damage.
Transverse (across the belt) cracks are
acceptable.
Longitudinal (direction of belt ribs) cracks that
intersect with transverse cracks are not
acceptable.
Inspect the belt
- Embedded debris
- Uneven/excessive rib wear
- Exposed belt cords
- Glazing (high heat)
If any of the above conditions are present,
the belt is unacceptable for reuse and must
be replaced.
