Tighten the clamps onto the track just above the bottom rollers. This keeps the door from rising on accident. Twist the clamp handle to tighten. [2] X Research source
If needed, use a ladder to safely reach the release rope and outlet. If the door opener is hard-wired to your garage, turn off the corresponding breakers or fuses to cut the power.
Measure the size of the holes in the spring’s adjustment collar to ensure you have winding bars with the correct diameter. Wear protective goggles and gloves in case the tension of the spring is accidentally released. Take note of how many ¼ turns you make to loosen the spring. You’ll need to twist it back to its original tension after the rollers are replaced. The torsion spring (or springs) are located on a steel shaft above and parallel to the garage door frame.
Only remove and replace one hinge and roller at a time. They hold the door in position, and removing multiple at once could make the door collapse. Use pliers or the claw of a hammer to pop the roller head out of the tracks if you can’t wiggle it out by hand. You may need a hammer to help tap the hinge out of place.
If you can’t wiggle the roller back into the track, use a hammer to tap it back into place.
Make sure to buy the correct number of replacement rollers you need before you start removing hinges.
Only bend one edge of the track. If you bend both, the roller (and door) may slip out of the track accidentally. Bend the track at a lower point if that means you can reach more comfortably or safely.
Do not remove the bottom hinges. Support cables are attached to these hinges, and removing them means the cables may snap and hurt you. [14] X Research source
If the spring was too loose before or the door was difficult to lift open, use this opportunity to adjust the spring tighter by making extra turns. Tighten the set screw once you’ve reached your desired tension. If you clamped the spring shaft, remove the clamp after the set screw is secure.
In most cases, any white lithium grease will lubricate the rollers without eroding them down the line. Avoid regular WD-40. It’s many people’s first choice, but it will cause damage to the rollers in the future.
