located on the right side of the system. See

screws holding the load cell summing box lid in
place and remove the lid. Refer to

6. Locate the damaged load cell cable and disconnect
the load cell connection wires by loosening the
corresponding flathead screw with a small flathead
screwdriver. Refer to

disconnect the wires that correspond to the
damaged load cell cable.

load cell summing box using the 7/16'' wrench. Refer
to
Figure 67 .
8. Remove the cable from the load cell summing box
and use the two 7/16'' wrenches to loosen the metal
attachments on the damaged load cell cable.
Remove the attachments indicated in

Figure 69 . You will need these attachments for the
new load cell cable.
