Lower Spreader Belt Tension Check/
Replacement
There are two sets of lower spreader belts on
the unit which will stretch and wear over time.
Belt stretching is automatically compensated for
by spring loaded tension arms.
Replace the belts if the spreader belt “teeth”
have been damaged, when the pins have worn,
or when the ribbons sag.
NOTE: Before replacing a
sagging belt, check to make sure
the tension spring has not been
compressed.
Mechanical movement and vibration can cause
the adjusting nut to compress the belt tensioning
spring. Before replacing a sagging ribbon, check
the position of the adjusting nut.
There should be a 1/4” gap between the
tensioning nuts and the fixed retaining plate
(Figure 7-29) to allow proper belt movement
during operation.
If belt sagging is corrected because the nut
must be moved out and the belt/pin is otherwise
sound, replacement will not be necessary.
Required Tools
15/16” wrench, pliers
Perform only when the unit is OFF
with power disconnected.
NOTE: Belts should be replaced
in left side/right side pairs to
prevent a single new belt from
creating an excessive pull to one
side.

and fixed plate.
