The parts of your garage door may wear out and they will need replacing. You can replace the easy-to-fix parts all by yourself by following through the following instructions. Fixing the cables and springs on your door might seem too difficult for you to handle, but by following the manufacturer’s instructions and using the right tools and proper parts you can fix it.
You will require the following tools and parts:
- Winding bars
- Safety hand gloves
- Safety glasses
- Locking pliers
- A drill
- Adjustable wrench set
- Bottom brackets
- Double-life torsion springs
- Lift cables
Here is the procedure you should follow to do overhead repairs of your garage door:
- Lock the door down tightly using locking pliers slightly above one of the rollers. This is to prevent the door from reversing back and hurting you as you wind the new springs. Also remember to unplug the door opener from the power outlet.
- Loosen and unwind the unbroken spring. Push the winding bar into the bottom hole of the winding shaft of the intact spring. Clamp the winding bar in place as you slacken the two setscrews. Fasten the other winding bar into the hole, and unwind the spring.
- Detach the springs from the middle bracket, by removing nuts and bolts and then sliding the springs into the end brackets
- By the help of locking pliers, clamp the torsion rod onto the bracket. Slacken off the setscrews on the left and right side of the cable drums and detach the cables.
- Remove the old spring. Slide the torsion bar to the right, on the left side of the door to remove the cable from the drum. Then remove the spring from the tube.
- Fix the left spring. With the cone facing the center bracket, slip the new spring on the torsion tube. Reinstall the cable drum and insert the torsion bar to the left-side bearing bracket.
- Fix the new center bearing slip onto the torsion bar. Install the right spring and shove the bearing into the cone and restore the drum. Fasten the cones onto the center bracket.
9. Change the rollers, bottom brackets and lift cables. Replace the new roller and bottom brackets, then wound the new cable.
- Thread the cables in the slot. Run the cables between the rollers and the doorjamb. Slip the lift cable stop onto the opening on the drum.
- Tighten the drums. Clamp the locking pliers on the torsion tube. Ensure it is locked in one place as you tighten the drums. Revolve the drum to wind the cable into the winding ruts. Make sure the cable is tight enough before you tighten up the setscrews. To ensure the door opens evenly, equalize tension on both sides.
- Wind the springs. Put the winding bar hooked on the cone and wind the springs in an upward motion. Make sure you make exact number of turns as recommended in the manual. Rotate the spring a quarter turn at a time.
13. When you are done wounding the spring, stretch the spring from the center using a winding bar, before you fasten the screws. Rotate the setscrews until they reach the torsion tube. Be careful not to over tighten the screws, as they can interfere with the torsion tube.
14. Lubricate the spring using the recommended garage door lubricant.
If you are not confident enough to do the work at your garage, hire a professional to avoid putting your well-being in jeopardy.
