Step 9

  • Use a pair of wire cutters or scissors to cut and remove the zip tie secured around the black, yellow, and green motor wires.
  • Take note of where this zip tie is located so it can be replaced during reassembly. If the cables inside the housing aren’t managed properly, the vacuum motor will not fit back inside the housing.

Step 10

  • Disconnect the two black motor wires from the switch mounted inside the carpet extractor housing.
  • This may require a significant amount of force; pull and wiggle the connector until it is free.
  • Do not worry about which wire is connected to which connector, as the motor’s polarity does not matter.

Step 12

              Crimp the New Wire Terminals
  • If your replacement vacuum motor does not have quick disconnects on the end of its wires, strip about half an inch of insulation off of each wire to install new crimp connectors.
  • Once the wires are stripped, install new 14-16 AWG insulated female crimp connectors onto the bare wire ends. Use a crimping tool to secure them.
