6.10 If the garage door comes off the floor when you pull down on the bar, and if the cone still won't loosen, tap the bar next to the cone with a hammer to force the cone beyond the swollen portion of shaft. Maintain a firm grip on the bar; keep it firmly inserted completely into the cone; and be prepared at all times for the cone to slip, break, explode or break free from the shaft and yank the bar down.
6.1 It is time now to unwind the old spring that is not broken. A few warnings are in order. NEVER, NEVER, NEVER touch a set screw without first inserting a properly fitting bar into the winding cone! Also, do not use box or socket wrenches for the set screws. If the cone slips, the wrench could break your hand in 10 spots before unwinding completely. It's my guess that this is the number one cause of trips to the emergency room for inexperienced homeowners fixing or replacing their springs.
While a sudden issue is usually easily repaired, a consistent issue that has gone unaddressed for months or years will likely require a total replacement. The problem is that garage doors have a number of heavy, powerful moving parts. If the door is working as it is designed, it can open and close hundreds and hundreds of times without issues. However, if there is even a small issue in the lifting mechanism that repeatedly influences the movement of the door, you will soon find that the damage caused over those hundreds of lifts can’t be fixed.
Keep in mind, the pulley is often cycled through an enclosed casing that is difficult to lubricate directly. By applying enough lubricant to the pulley, you’re ensuring that the whole lifting mechanism is properly lubricated. Furthermore, a jam in this portion of the lifting mechanism is a time-consuming and potentially labor expensive repair that requires a service professional.
Garage doors make life easier, particularly when you’re arriving home in the middle of a rainstorm. It’s easy to take the convenience a garage door provides for granted -- until it stops working properly. The door loses its visual appeal instantly, stuck there half-open. This type of situation also raises security concerns as a simple trip to the store can become a headache. Simple fixes when a garage door gets stuck halfway may prevent it from happening again.
Nate was very courteous and professional and called to let me know that he was about 30 minutes from my house. I had purchased a new Sears garage door opener, but when Nate arrived at my home, he inspected the existing unit and told me that it was still in good shape except for a worn out part. Nate procured the new part and brought it to my home this morning. The unit was repaired in about 10 minutes! The existing unit was just over five years old, so I'm glad I will get some more use out of it. http://youtube.com/v/Z_eZc-kh40c?version=3
9.9 Go to the other side of the garage door and insert the end of the cable into the drum. Rotate the drum until the cable is tight. Slide the drum against the bearing and push the shaft to the right. The marks should line up. If they don't, figure out why and correct the problem. It could be a stuck cable, the garage floor may have shifted, or the vertical angle that helps support the bearing plate may have loosened and shifted. Many garage doors have been installed with a gap between a drum and a bearing plate. The cable drums should always be flush against the race of the bearings. http://youtu.be/Z_eZc-kh40c
I went on Garage Door Nation website to look at the conversion chart from 1 to 2 torsion springs. For my 1 spring, size 2"/0.250ID/30.5" length, they recommended 2 of 2"/0.207ID/24" length. I got this kit from Amazon for $64 with $11 overnight shipping even though I could get free shipping through Prime over the weekend, but I couldn't wait for 3 more painful days. Installed it followed YouTube video. Worked better than my old one, a lot quieter. Check the video if you want to install one yourself. Professional installation costs hundreds of $$$:
If your garage door is equipped with only one torsion spring, it will be much harder to get your door open. You will need to get 2-3 people to help lift the door up because the full weight can be anywhere from 150 to 300 pounds. We don’t recommend lifting the door when the spring break's due to the danger of it falling on someone. If you absolutely must get your garage door open, raw strength is what you need. When you get the door in the up position, use vise-grips or a c-clamp on the track below the bottom roller to hold the door in the up position.
If you are not sure if your door had the correct springs, we recommend that you weigh your door using an analog scale. From my own field experience I would estimate that at least 10% of the doors have the incorrect springs on them. In addition to this, most manufacturers spring their doors using a 20 pound window. We like to improve the garage door balance.
