Replacing Worn Ribbons
Required Tools
3/8”, 9/16”, 3/4” wrenches, pliers
Perform only when the unit is OFF
with power disconnected.
Verify the replacement ribbons are the
correct size and sufficient quantity for
completing the procedure. Refer to the
PARTS LIST .
Turn power OFF at the main disconnect
switch.
Only if the front bypass ribbon set is to
be replaced:
Turn ON the compressed air supply
to the unit.
Locate the right pneumatic panel (Fig-
ure 7-33) just to the right of the center
of the machine.
On the bottom of this unit is the main
solenoid valve. Locate the override
screw on this valve (Figure 7-34).
Use a small screwdriver to push in
the lockout screw and turn it 1/4 turn
clockwise to lock it in the “in” position.
This allows compressed air to flow to
the pneumatic control solenoids.
On the right pneumatic panel, locate
the solenoid air valve for the front by-
pass conveyor (Figure 7-37) and locate
its lockout screw.
Use a small screwdriver to push in
the lockout screw and turn it 1/4 turn
clockwise to lock it in the “in” posi-
tion. The front bypass conveyor should
rise.
Release tension on the appropriate rib-
bon set following the Discharge/ByPass
Conveyors Ribbon Tension Adjustment
procedure earlier in this section.

Pull the worn ribbons around their tracks
until all the lacing clips are accessible and
aligned.
Remove the connecting pin from an old
ribbon and attach a new ribbon to one
end.
WARNING
Never turn on power while
pulling the ribbons through.
This is dangerous and
unnecessary.
Pull the old ribbon through until the new
ribbon is in place.
Disconnect the old ribbon and secure the
replacement ribbon with a new pin. For
discharge and rear bypass ribbons, make
sure the 1/2 right twist is maintained on
the underside of their respective conveyors
(Figure 7-40).
Repeat Steps 6 to 8 to replace additional
worn ribbons. Stagger the positions of the
lacing clips to give the flatwork a smooth
flow.
Adjust ribbon tension following the
Discharge/ByPass Conveyors Ribbon
Tension Adjustment procedure earlier
in this section.
If the front bypass ribbon set was replaced,
lower the conveyor by reversing Step 3.
