How to adjust garage door torsion springs?
You need 2 @ 3/8″ rods around 18″ long. Insert one in the hole of the hub at the end of the spring nearest the door header. CAREFULLY loosen the set screws and lift the rod 1/4 turn. Insert the other rod in the hole below and do the same. Once you have the desired tension, allow the rod to rest against the door header and re-tighten the set screws. Repeat for the other spring (if a 16′ door).

Admin: If you need to release tension, reverse the process. Use the rods to loosen the spring, then retighten the set screws.
Now, the obligatory word of caution. These springs are under a lot of tension. If the rod is not firmly seated in the hub, it can fly out and hurt you badly. If you are at all uncomfortable with this process, Don’t do it! Be sure you are using a sturdy ladder, and are properly positioned to make this adjustment comfortably. Don’t overreach. Hope this helps.

Admin: Do you see that thing at the end of the spring with the holes in it? Notice the screw? That’s what holds the tension on the spring. Get two rods about 12 to 14 inches long that will fit the holes (longer rods=less effort, if you have room to work). Place one of the rods in a hole and get a good grip. Now loosen the screw (be very careful because the tension on the things can be tremendous). Using the rods, walk the star around the tensioning rod alternating holes until you have released the tension. Next, reattach and align the cables and reverse the un-tensioning drill. Be sure to tighten the set screw very tight to prevent slippage.
