There are two types of operators, trolley and drawbar. On trolley type operators the drawbar arm pushes and pulls the top of the door to open and close it. On jackshaft operators the operator turns the torsion shaft to open and close the door. On this type of operator the cables normally loosen momentarily until the weight of the door pulls on the cables. Sometimes, however, the cables come off the drums when closing the door from the open position. The best solution to prevent this problem is to pitch the horizontal tracks at least an inch for every foot of track length. This allows the weight of the door to push down into the opening, thereby keeping the cables on the drums tight as the door closes. When pitching the tracks is neither possible nor feasible, a second solution is to install pusher springs in the backs of the tracks to push the door down from the open position. This has been a helpful solution for many of the residential Liftmaster Model 8500 Openers that turn the torsion shaft to operate the door.
A third option is to install a larger drive sprocket on the end of the torsion shaft. This will reduce the turning speed of the torsion shaft rotation possibly eliminating the possibility of the cables coming loose. A fourth solution is to install cable keepers. These will pull a few inches of loose cable away from each drum. A fifth solution from the early years in the trade was to install 12″ of screen door spring, hooking one end to the bottom cable loop. We would stretch the top eight or more inches and secure it to the cable. The spring would pull the slack in the cables to prevent them from coming off the drums.

Torsion springs are mounted on a stationary metal shaft located above
and parallel to the top of the garage door frame. They are attached on one end to a stationary plate located above the center of the door frame. extend along the shaft, and work by twisting as the garage door closes by means of cables attached to each side of the lowest garage makes it easier to lift the garage door from its closed position. Side mounted springs are long heavy springs mounted on each side of the upper garage door track. Through the use of pulleys, they perform the same function as the torsion springs... they come under tension when the garage door is closed to make lifting the door easier. IMPORTANT TIP: Always replace garage door springs as This may not be obvious to a novice, but it makes sense. If one spring has broken, can the other spring's demise be far behind? Add that little bit of common sense to the fact that the strength of a spring decreases with time and Having faulty and/or weak springs can be much more than a hassle if not
properly taken care of! It might not be much of a consolation having your garage door came crashing down on your classic Ford! Although that may not happen, is it worth the risk? Always change both springs...save your car! The use of a new spring with an old spring can cause an imbalance in the door that cannot be corrected through normal spring adjustment. You must release the tension on the garage door springs before attemptingThis is accomplished by opening the garage door as fully as possible until it hits the stop bolt on theHold the garage door in this position by attaching a C-clamp to the track at a point below the lowest This is true even if you have a garage door opener. Just because the door is open does not mean that the spring tension is fully released. release rope to disconnect the opener from the door and push the door up as far as you can without damaging the opener. Then clamp as described above. If there are safety cables installed, they must be disconnected and removed
The old spring is attached at two points. One end is a fixed attachment to the garage door track or wood frame. The other end is attached to a pulley through which the garage door cable is threaded. these two attachments and reattach the new spring in the same way. to twist the garage door cable when reattaching the pulley. While the pulley is disconnected from the spring, give it a quick hard look. If it appears that the pulley bearings are very sloppy and have lots of wobble,There is no repair other than replacement. function more smoothly and save you additional work later. And you might as well check the stationary pulleys, too, while you are at it! Once all attachments are completed, test the door once for proper function before reattaching the safety cables. You may find that the new springs may be too "lively" and the door may not close all the way. If that is the case, you will have to look at the way the bare end of the garage door cable is
attached to the garage door track, and loosen an inch or two. This end may be simply looped through the holes in the track, or it could be attached by means of a special clip and an S-hook. In either case adjust both sides equally either by shortening the cable or by repositioning the S-hook in a different hole inThe springs should visually be in about the same position when extended fully (door in down position). Of course, if you do not have enough tension in the springs, and want to make manual opening of the door easier, you may adjust the garage door cable into a (NOTE: Some modern torsion springs can be adjusted with a special adapter and an electric drill. I would suggest visiting the manufacturer's website concerning the appropriate adjustment method. refers to typical manual adjustment.) Adjustment to torsion springs can be dangerous because they must be adjusted with the door down and the spring under tension.
Torsion springs must be adjusted with the door in the down position. sure to have all your tools inside before closing the door unless you have an alternate access door to the garage! 1) Secure the door in place by putting a C-clamp on the garage door track above the bottom-most door roller. As you adjust the spring more tightly, there is the chance that the door may begin to rise if you overtighten it... a 2) The moveable end of each spring is attached to an adjustment collar. a set screw in the adjustment collar that locks the spring in a position of tension on the center shaft. The adjustment collar also has a series of holesYou will need to insert a metal rod into one of theseThe rod is used to hold the collar in position as the set screw isSince it is unlikely that you will find an adjustment rod in your garage, measure the diameter of the holes and purchase a section of steel rod... at least 18" to 24" long... at any hardware store.
If solid steel rod is not available, a threaded rod is acceptable for this purpose. 3) Before making any adjustments, observe the original position of the set screw to see if there are "flats" that the set screw should be set into. These are special depressed or flattened areas of the shaft that allow the set screw to hold more securely. A warning... this can be a dangerous procedure because of the tension on the spring, so care must be taken at all times to prevent bodily injury! Eye protection and gloves are recommended! 4) The adjusting rod must be solidly in the hole in the collar, and the set screw is loosened while holding the rod inThe rod is then used to turn the collar to tighten or loosen the tension on the spring. While holding the collar in the new position, the set screw is tightened to lock collar the new position. Both torsion springs must be adjusted equally to assure balance in the door. 5) Depending on whether you wish to increase the opening force or
