3. Follow the proper procedure to remove the torque tube assembly (key 9).
4. Remove the bearing bolts (key 5), displacer rod assembly, and driver bearing.
Note
Be sure to install the driver bearing so its knife edge is pointing up when the torque tube arm is mounted in the desired orientation.
Since changing the mounting position of the torque tube arm by 180_ will change controller or transmitter action from direct to
reverse or vice versa, controller/transmitter action must be reversed from what it was before the mounting method was changed.
5. Install the driver bearing, displacer rod assembly, and bearing bolts (key 5) into the torque tube arm. Install a new
arm gasket. Install the torque tube arm on the sensor head or process vessel and secure it with the proper bolting
(keys 19 and 20).
6. Install the torque tube assembly. Install the displacer.
7. Install the sensor head and controller/transmitter. Calibrate the controller/transmitter following the procedures
given in the controller/transmitter instruction manual.

When corresponding with your
sensor serial number. Each sensor is assigned a serial number which is stamped on a nameplate (key 54, not shown)
attached to the torque tube arm. This same number also appears on the controller/ transmitter nameplate when a
complete controller/ transmitter‐sensor unit is shipped from the factory.
