Upper Spreader Belt Tension
Adjustment
Adjust tension of the upper spreader belt when
it begins to sag noticeably or to skip on the timed
pulley. Both conditions cause excessive wear on
the belt and shorten its life.
Required Tools
9/16”, 3/8” wrenches
Perform only when the unit is OFF
with power disconnected.
Turn power OFF at the main disconnect
switch.
Open the left endframe door.
Locate the upper spreader belt tension
adjustment bolts (Figure 7-22, A).
Loosen the locknuts (Figure 7-22, B)
and turn each bolt the same number of
turns clockwise until the belt is properly
tensioned.
Tighten the locknuts to secure the adjust-
ment.
Close and secure the left endframe door.
Start the unit and feed several pieces to
verify the adjustment.
Repeat Steps 1 to 7 until the adjustment
is satisfactory.

Upper Spreader Belt Replacement
Replace the upper spreader belt when it can
no longer be properly tensioned or if it becomes
excessively worn, cracked or frayed.

Perform only when the unit is OFF
with power disconnected.

riage assemblies toward the center of the

moving during the following procedure.
