Cleaning and lubricating all the mechanisms (including the lock) will keep them functioning smoothly and efficiently. Most of the time, the issue can be easily solved. This guide will help you understand how to repair your bifold doors when they become difficult to open or close. Cracked Pivot Pins A bifold door is made up of two panels that slide along a track within the floor and head jambs. They pivot around pins that are placed in the corners closest to the frame of one panel and a guide is put on the top of the other panel to help it move along the track. If your bifold is wobbling or rattling, you might need to replace the pivot pin or anchor. The pivot pins of bifolding doors are connected to the track via brackets that are fixed into the side jamb as well as the floor or headjamb. The bottom bracket is notched to adjust the direction of the door with respect to the floor or jamb. Sometimes the pivot pins crack or break. This usually happens from twisting force that is applied to the pivot pin while moving long logs in a grapple or track loader. This problem can often be resolved by loosening the set screws on the bracket's bottom, and raising the door slightly. This will align the door edge with the frame and will eliminate the scrape. It is not uncommon to see the pivot on bifolding doors cracked or broken. The pin is subjected more force and twisting than to the coupler or thumb. This is especially true for older pins that are composed of soft materials. If the pin is broken and you need to remove it from the door by prying it out with an flat-headed screwdriver or pliers. Clean the coupler or thumb and replace it with a brand new pin. Make sure the pin's diameter is the same as the old pin. Use an appropriate punch with the right end diameter to press the new pin
