The Ten Steps Required to Replace Broken Garage door springs
1. Safety First: Because garage door replacement is quite dangerous, you should go about it smartly by planning everything out and keeping in mind that the springs are under tension. Wear safety goggles, presume the springs will break, don't use older winder cones, and unplug the power cord before working. It's your responsibility to do the job right the first time.
2. Gathering Tools: You require the right tools When it comes to fixing your broken spring, you need a 1/2" by 36" steel rod cut in half or two 1/2" by 18" winding bars, an adjustable wrench, 10" vise grips, torsion springs, a firm ladder, a cleaning rag, a ruler, a file, a socket wrench, sockets, and good lighting.
3. Measuring Old and New Springs: Measuring old and new springs is important because you want to make sure that you're putting in the right size of springs. Lay the springs on the garage floor and measure inside diameters, 20 coils, and lengths to have a good idea of the wire sizes and whether or not they're ultimately a perfect fit.
4. Marking the Torsion Shaft: When marking the shaft and cable drums, you can go about it by using a file pen or marking pen. Also remember that the cable is powerful enough to rip through bone and muscle, so don't grab the shaft and don't touch the cable drums if the springs are still wound in tightly. Unwind them first.
5. Unwinding Old Springs: Speaking of which, when it comes to unwinding the old springs, never touch a set screw unless you've inserted the right bar into the winding cone. You should also keep the bar in the cone at all times. Finally, make use of at least 18" long winding bars that fit like a glove on the winding cone.
6. Loosening Torsion Hardware: After the old springs have been unwound, it's now time to loosen the entire torsion hardware altogether. Slotted spring brackets should be secured with the vise grip, then slide both springs toward the cable drums, out above the top of the garage door. Afterwards, loosen setscrews, slide the drum away, and file the shaft if the ridges are worn.
7. Replacing Springs: Spring replacement entails sliding the drum away from the bearing, filing the end of the shaft as required, lubing up the bearing, pulling the shaft out of the head plate, sliding off the old spring, putting in the new spring, sliding the spring to the spring anchor, reinstalling the cable drum, straightening the bearing plate, and putting everything back together.
8. Reinstalling Torsion Hardware: This step of the process involves sliding the drum to the shaft, tightening the setscrews, sliding the shaft's end to the bearing plate's end, rotating the garage door shaft to tighten the cable on the drum, going to the other side of the garage door to insert the cable's end into the drum, and securing the torsion springs in the middle.
9. Winding New Springs: Don't forget to wind the new springs so that your garage door would safely work good as new. First, mark the shaft just over the winding cone. Then put in your winding bar into the winding cone. Cycle from raising the first bar, turning, inserting the second bar, and removing the first bar.
10. Check and Lube Garage Door and Reconnect Opener: Restrain and raise your garage door, check its balance, and check to see if it's working properly. If the springs are installed properly, expect it to do as it's expected to do (it opens, closes, and opens halfway as you want it to do so). Finally, engage and reengage the garage door opener before plugging the contraption back in.
