How to replace the sliding door pulley if it is broken? What is the solution?

Now many people will choose sliding doors when decorating their houses, which is more convenient and practical, but pay attention to the installation and quality of sliding door pulley. The pulley track is an important part of sliding door. If the sliding door pulley is broken, it will affect the overall appearance and use. Next, let's see how to replace the sliding door pulley when it is broken? What is the solution?
1、 How to replace the sliding door pulley if it is broken?
First, lift one end of the sliding door vertically on the ground with one hand, and slide the lower end of the sliding door pulley with the other hand to hold the door and window pulley. Then lift one end of the door off the track and put it down. Similarly, lift the other end of the balcony sliding door off the track. Then hold both ends of the sliding door with both hands and lift it. In this process, please pay attention to safety and do your best.
1. For disassembling the sliding door pulley, it is recommended to lay the door flat on the ground, and then observe the sliding door. Usually, there is wool at one end of the door frame, some directly pasted on the door frame, and some pasted on the door frame.
2. As long as the wool is fastened on the door frame, pull the wool to the second screw hole. The bottom of the screw hole is the screw hole of the door and window pulley, and the top is the screw hole for fixing the aluminum alloy frame. Insert a 6mm hex wrench into the round hole.
3. At this time, press the door and window pulley of the sliding door tightly by hand, remove the screw with a tool, and then pull out the door and window pulley. This is the same way to remove the sliding door pulley as other door and window pulleys.
4. Push the upper pulley flat into the gap between the revolving cover and the inner wall of the door frame. To keep the upper pulley at a certain distance, clip a piece of cardboard between the upper edge of the door frame and the plane of the upper pulley. Then tighten the screws.
5. Install the upper pulley. Put the cardboard.
6. Turn the sliding door over, stand up, insert the screw through the round hole at the bottom, hold the lower pulley with your hand, make the screw hole of the adjusting box perpendicular to the screw, and the screw is easy to screw in. Use a 5mm hex wrench to turn the screw.
7. Screw the screw into the adjustment box, and then turn it five times. So far, the installation of the side push door and side push wheel has been completed.
2、 Now let me tell you, what is the solution to the broken sliding door pulley?
1. Pulley derailment
If this happens, the door frame will slide directly on the track, which will be very laborious to use and will damage the door frame. It is recommended to lift the door slightly to let the pulley return to the track.
2. Pulley damaged
This may be that the pulley is damaged. If this happens, it means that the door is too heavy, resulting in the pulley can not bear the gravity, deformation, serious crushing or pulley bearing damage, resulting in wheel seizure and unusable, so the pulley needs to be replaced.
3. Track deformation
If the pulley is not damaged, the track may be deformed. Generally speaking, under the weight of external force, the track will be deformed, making the pulley unable to slide normally, or there are sundries inside the track, so it is necessary to repair and clean the track in time.
