Cleaning and lubricating all the mechanisms (including the lock) will keep them running smoothly and efficiently. The most common issue is something small that is easily fixed. This guide will show you how to fix your bifold doors if they become difficult to open or close. Cracked Pivot Pins A bifold door is comprised of two panels that slide along a track in 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 placed on top of the other panel to allow it to slide along the track. If your bifold is wobbling or rattling, you might need to replace the pivot pin or anchor. The pivot pins on bifold doors are fixed to the track through brackets that are screwed onto both the side jamb and the floor or head jamb. The bottom bracket is notched to adjust the direction of the door with respect to the floor or jamb. Occasionally, the pivot pins break or break off. This usually happens from twisting force that is applied to the pivot pin while moving long logs in a track loader or grapple. can be resolved by loosening the set screws on the bracket's bottom and raising the door a bit. This will align the edge of the door in line with the frame and remove the scrape. It is not uncommon to find the main pivot pin on bifold doors cracked or broken. The pin is exposed to more force and twisting than to the thumb or coupler. This is especially true with older pins that are made of a soft material. If the pin is damaged and you need to remove it from the door by squeezing it out with a flat head screwdriver or pliers. After cleaning the coupler, or thumb replace it with a new pin. Ensure the pin's diameter is the same as the old pin and use an appropriate punch with the right end diameter to press the new pin into position.
