Replacing hardware on your bifold doors sometimes requires changing out the pivot pins. The pivot pins are on the top and bottom edges of the door. They fit into the bottom bracket and the pivot bracket in the upper track. Some replacement pivot brackets require a different diameter pivot pin, while replacement lower brackets might require a different pivot head. The removal process depends on the type of pivot pin.
Things You'll Need
Open the bifold door completely so both panels are against each other.
Grab both panels together at the sides, then lift up to compress the spring on the top pivot pin. Swing the bottom half of the panels away from the lower pin bracket. Pull down to disengage the top pivot pin from the upper track bracket.
Place the bifold door on a set of saw horses or a flat surface. Keep the panels stacked together for less difficult handling.
Remove the screws securing the top pivot pin mounting plate to the door with a Phillips screwdriver. Many older bifold doors use a mounting plate. Grasp the top of the pivot pin with a pair of pliers and pull it out of the door.
Insert a flat-head screwdriver between the bottom of the pivot hinge flange and the door, if you have pins with no mounting bracket. These types of pins simply push into the hole in the door, and are tight. Pry the flange away from the door slightly with the screwdriver.
Grab the top of the pivot pin with a pair of vise grips. Twist the pin left to right while pulling it out of the door.
