WARNING
The chain and power must
both remain disconnected
during this procedure. Do
not reconnect either of these
until the entire procedure
is completed.
4. The friction material must be applied
while the return ribbon drive roll turns
freely:
a) Open the right endframe door and lo-
cate the drive chain (Figure 7-35, A).
b) Release tension on the chain; refer to
Drive Chain Tension Adjustment on
page 7-23 .
c) Locate the clips that secure the ends of
the drive chain together.
d) Use a chain puller to relieve tension at
the site of the clips and remove them.
e) Remove the chain from the return rib -
bon drive roll sprocket (B).
f) Close and secure the right endframe
door.
5. Remove the front receiving shelf.
6. Pull the return ribbons around their tracks
until all the lacing clips are accessible and
aligned at the front of the unit. Remove
the connecting pins and position the return
ribbon ends away from any contact with
the drive roll.
7. Place a tarp, plastic drop cloth, heavy pa -
per, or another temporary protective cov-
ering over the floor underneath the unit.
8. Remove the screws at each end of the
drive roll (Figure 7-36) that hold the fric-
tion material in place. Set aside for re-use.
9. Pull or cut off the old friction material. As
you do so, note the direction of the spiral
winding.
10. Remove the old cement from the drive
roll with a scraper, coarse sandpaper, or a
steel brush. Wipe away remaining residue
with a clean cloth. Make sure the roll’s
surface is down to bare metal, and that it
is completely clean and dry.
CAUTION
You must be down to bare
metal before installing the
new cover or it may not
adhere properly.
