1. Remove power to the indicator.
2. Remove the platform access cover then the junction box cover and disconnect the
failed load cell cable at the junction box. Loosen the gland bushing and tie a string
or wire to the end of the cable to act as a pull wire. Check for all cells to have wire
markers on the cable ends. If not, identify cells with wire markers or other means.
Disconnect the faulty load cells' wires from the terminal block.
3. Lift the platform end with a forklift or heavy pry bar using wood blocks for safety.
4. Remove the load cell mounting bolts (use a 1 1/8" socket), and remove the load
cell, pulling the load cell cable through the scale while leaving a pull string/wire in
the scale.
5. Remove the foot assembly from the old cell and install on the new load cell, using
anti-seize on the bolt threads.
6. Disconnect the pull string/wire from the old cell's cable and attach to the new load
cells cable end. Pull the cable of the new load cell through to the junction box.
Mount the load cell using anti-seize on the mounting bolts, torque to 250 ft/lbs.
7. Lower the scale to the surface removing the safety blocks.

screws to 18-20 in/lbs. Replace the platform access cover .
