    Power Window - Plastic pulley repair

    One day, selecting the driver's side door window up, I heard something snap / break. Then the window would go down without any issues, but it had trouble going up.

    Instead of buying a new or junkyard window regulator, I decided to try to repair it.

    A patio door wheel was found, but in was slightly smaller in diameter. The good thing about this pulley, it had a center bearing. So a screw and nut could pinch the pulley.

    The repair.

    Remove the regulator from the car.
    Drill out the aluminum stud. Select a drill size that will remove the stud, but not damage the steel frame. The stud has a shoulder that has a bigger diameter for the pulley, but has a smaller diameter for the frame.

    Found all of the hardware at Home Depot.
    1/4" x 3/4" countersink Phillips screw and nut.
    1/4" washer.
    Prime-line pulley number D-1504 with a grove diameter of 1" and 0.330 thick.

    The original pulley has a grove of about 1.6 inches and .210 inches thick.

    Hope this helps.
