It’s possible that the rollers on your garage door have been worn out and need to be replaced if you’ve noticed that it doesn’t open as silently or as smoothly as it once did. What steps do you take to do it on your own? Because you will be working with a hefty door as well as springs and cables that are tight, you should always put safety first even though replacing rollers is not a particularly difficult task. As a result of this, we have developed a comprehensive guide that will assist you with safely and efficiently replacing your rollers using only a limited number of tools. Continue reading this article if you are prepared to get rid of that outdated garage door.
Top and middle rollers
Verify that the garage door is shut all the way. It is advisable to replace all of the rollers, with the exception of the set at the bottom, while the door is closed. This is carried out for safety-related reasons. By doing this, you can stop the door from sliding open while you work on it and stop the panels from sagging once you take the hinges off. C-clamps should be fastened to the door track directly above the bottom rollers to hold the door in place. Close the clamps after positioning them immediately above the bottom rollers of the track. As a result, if the door is left unattended, it won’t open on its own. By rotating the clamp’s handle, you can increase security.
Remove the plug from the electric garage door opener, and then unplug it.
Because of this, it will be impossible for anyone to open the door accidentally while you are working. To stop the garage door opener from functioning, pull the release cord located on it, and then unplug it from the wall to make it even safer. In order to reach the outlet and the release rope in a secure manner, you can, if necessary, make use of a ladder. To turn off the power to your garage door opener, if it is hardwired into your garage, you will need to switch off the related breakers or fuses.
Steel bars are used to unwind torsion springs by wrapping them around the springs themselves.
To prevent the spring from moving, secure it by inserting one of the winding bars into the hole in the adjustment collar (found on either the right or left end of the spring). After that, make sure the winding bar is still in its original position before removing the set screw with a screwdriver. You may wind the spring by turning the winding bar such that it rotates the spring a quarter turn at a time. The make the garage door easier to move, twist the cable so that it passes the pulley in the opposite way from how it was originally installed. To prevent the spring shaft from moving, either turn the set screw clockwise or clamp it. To ensure that you have winding bars of the appropriate size, you should first measure the diameter of the holes in the adjustment collar of the spring.
Put on safety gear like gloves and eyewear just in case the tension of the spring accidentally releases.
Take note of the total number of 14 spins that must be completed before the spring will begin to move. After you have completed changing the rollers, you will need to readjust the tension to how it was before. The torsion spring is mounted on a steel shaft that is positioned above the garage door frame and runs parallel to it (or springs).
Take the door hinge and roller off one at a time, then disassemble the door.
Begin by removing the hinges that are located in the middle of the panel, midway between the bottom and the top. You can begin with the screw on the left or the screw on the right, and then work your way around the entire thing. You can remove the roller that the hinge is holding by raising it off the door and moving it out of the door track. This is done by lifting the hinge that is attached to the door.
It is recommended that you only remove and replace a single roller and hinge at a time. Because they are holding the door up, if you remove them all at once it could result in the door falling. In the event that you are unable to remove the roller head from the tracks by hand, you can resort to using pliers or the claw of a hammer. To remove the hinge from its mounting, you might need to use a hammer.
After removing the previous roller from the hinge, the new roller can then be installed in its place. After the hinge has been removed, you may easily remove the old roller by lifting it out of its mounting holes. There is no requirement for any tools to complete this task. Slide the new roller into the holes in the hinge after removing the old roller and either set it aside or throw it away.
Put the roller back into the track, and after that, reattach the door’s hinges to the door.
When the roller’s head is properly positioned within the track, the bolt holes on the hinge should be aligned with the corresponding holes on the garage door. To complete the process of replacing the roller, you will need to tighten any nuts or screws that are holding the hinge in place. Use a hammer to tap the roller back into position if you find that you are unable to move it with your fingers. Apply this technique to each hinge and roller, with the exception of the two that are located at the bottom.
To prevent the door from becoming unstable in its frame, make sure that you remove only one hinge at a time.
A standard garage door of 7 feet (2.1 meters) in height contains 10 rollers and hinges, with five located on each side. There are 12 rollers and hinges on a garage door that is 8 feet tall (2.4 m) (6 per side). Before beginning to disassemble the hinge, check to make sure that you have the appropriate number of replacement rollers.
You can open the track towards the top of the frame by using pliers to open the seam where the track meets the frame.
Find the point at which the piece of track that runs along the ceiling on one side of the frame is joined to the piece of track that is straight and runs along the other side of the frame. Bend the inside edge of the piece outward by approximately one inch using pliers or the claw of the hammer (2.5 cm). Simply curve the outside of one of the tracks. If you bend the roller and door, there is a chance that they will accidentally slide out of the track. If bending the track at a lower position will make it easier or safer to achieve the goal, then you should definitely do so.
