Buy a bottle of lithium grease or garage door oil. Do not use general lubricating oil similar to WD-40. Lithium base grease is required to lubricate garage doors. You can usually buy it in a hardware store or Taobao. Of course, there are some lubricants specially used to lubricate garage doors. Do not use oil. Compared with garage door lubricating oil, the oil is easier to attract dust and drip. Before use, read the instructions to see if the product is suitable for use on the garage door.
Open the garage door and spray lubricating oil on each hinge. Gently lift the garage door by hand, and then spray lubricating oil on the hinge in contact with the guide rail. This can lubricate the moving parts on the door and make the door open and close more smoothly. Spray 1-2 times on each hinge and spray lubricating oil on each side.
Lubricate the rollers. The roller is a movable part on the garage door, which is fixed on the hinge. Inside these rollers are small ball bearings. Only after they are fully lubricated can they open and close the door smoothly. Insert a thin tube at the outlet of the spray tank and spray the lubricating oil into the roller. Wipe off the lubricating oil, or the garage door will be unstable. Each visible ball bearing shall be sprayed with lubricating oil. Note that lubricating oil does not need to be sprayed on the nylon roller.
The spring and bearing plate are also sprayed with lubricating oil. The spring is usually located on the top of the garage door and also needs to be fully lubricated. The bearing plate is a circular part that can be moved on both sides of the spring. Spray lubricating oil on the spring and then on the central area of the bearing plate. Then try to open and close the door to make the lubricating oil more evenly applied. If the spring is broken or bent, it is best to replace it with a new spring before lubrication.
Potential cost: if you want to upgrade your door to add windows, it is expensive to transform the existing garage door, and you may damage your door in the process. You need to determine whether updating garage doors will make them unbalanced. Because when you add windows, the weight of the door changes.
Spray the top of the rail with lubricating oil. The track is where the chain slides and extends along the roof. The top of the track is where the chain really touches when sliding, so it also needs to be sprayed with lubricating oil. Spray lubricating oil on the top of the track, and then wipe it evenly with a rag. There is a natural protective agent on the chain, so there is no need for regular lubrication. There is no need to spray lubricating oil at the bottom of the track.
