3. Disconnect the four (4) wires from the four-pin Feedthrough. Note and record position of wire colors to
their corresponding pins. Expected: 1 = Red, 2 = Gray, 3 = Yellow, and 4 = Black. Refer to Table 4-15 IGV
Feedthrough Wiring Order on page 92.
NOTE
The colors associated with each pin could vary, so be sure to identify those on the respective compressor.
4. Remove the IGV Motor assembly by pulling away from worm shaft. Refer to Figure 4-56 IGV Motor
Assembly Removal on page 88. Support the bottom of the IGV Motor to prevent damage to the motor
shaft. A light tap on the motor locating screw with a tool may help release the motor shaft from the
worm gear.
5. If necessary, using a Stepper Motor Driver, turn the worm gear and Vane Drive assembly to position the
motor shaft so that locking set screw is aligned with the hole shown in Figure 4-54 Set Screw Removal.
Use needle-nose pliers or similar tool to turn the worm gear if a Stepper Motor Driver is not available.
6. Remove the set screw completely using a 2.5 mm hex bit to release the motor from the worm gear.
