3. Carefully rotate the ball to the open position after the actuator is disconnected. Make sure the ball will not rotate

(see warning above). Provide support for the ball during the following disassembly.

4. Unscrew the pipe plug (key 25). (The pipe plug is optional and may not be available.)

5. Working from the small end of the groove pin (key 7), use a pin punch to drive the groove pin out of the ball ear and

follower shaft.

Note

All NPS 1 Micro-Notch constructions use a one piece shaft. They do not have a follower shaft.

6. Locate the small end of the taper key (key 4, figure 14). Using a pin punch on the smaller end of the taper key, drive

it out of the ball (key 2) and drive shaft (key 6). Note: driving the taper key in the wrong direction will tighten it.

Note

The new ball/shaft assembly (key 48) does not require a thrust washer (key 38) in valves ordered after November 01, 200 1.

Discard the thrust washer in valves ordered prior to this date when new ball/shaft assemblies are used as spare parts.

Figure 17 shows the informational tag that is attached with the new ball/shaft assembly when shipped as a spare part. Refer to

figure 16 for dimensions of the ball in the ball/shaft assembly.
