Check the diagrams of your model for the exact location and the correct installation of this part. You will need a wrench to remove and secure the hardware that holds the idler pulley.

Removed and replaced pulleys, drive belt and controller. Still having a problem with reinstall of brake reset spring. Have searched high and low for diagram, instructions, video, etc. to show how to reinstall the spring. Absolutely nothing for my model relating to reinstallation of the brake reset spring. Dozens of videos for most any other repair.
