Maintenance
b. After disconnecting power to the
machine and removing all panels
necessary for access to the drive
belts, use the following method to
verify that the V-belts are properly
tensioned. Belt deflection should be
measured as close to the center of
the span length as possible. A set
force should be applied in the center
of the length, as specified in the
table below. Belt tension is adjusted
by turning the set screw on the idler
pulley. Turning the set screw
clockwise tighten the belt, and vice
versa.
c. Verify that V-belts are properly
aligned by checking pulley
alignment. Place a straightedge
across both pulley faces.
The straight edge should make
contact with the pulleys in four
places.
See figure.
