These instructions are for doors with cable drums and cables that look similar to those in the picture below. The next part beyond the end of the spring assembly is the cable drum. The drum is cast aluminum alloy 4" in diameter and 12.6" in circumference around the flat portion. Just beyond the cable drum is the end bearing plate. The cable unwraps off the back of the drum between the drum and the garage wall or jamb and travels down alongside the door, inside the track brackets and behind the roller stems as shown.
Doors with extension springs have two sets of pulleys (which are sometimes called sheaves): one at the end of each spring and one at the top of the vertical door track. They also have two cables on each side. One cable attaches to the bottom of the door, runs up and over the pulley above the door and around the spring pulley and then attaches to the door track bracket. The other cables are safety cables that run through the middle of the springs and are fixed to a track bracket at both ends. These cables restrain the springs if they break under tension. All extension springs must have safety cables.

If the door opens this way, then there’s probably something wrong with the garage door opener. It’s a good idea to make sure the opener is plugged into its nearby power outlet. Also, make sure the circuit breaker for the garage door opener hasn’t flipped to the “OFF” position. If it has, then there may be an electrical issue that your garage door specialist should check out.
Install the center bearing and the right spring, then secure the cones. Slide the torsion bar to the left then add the center bearing. Slide the right spring onto the bar and press the bearing into the stationary cone. Connect both of the stationary cones to the center bracket with the nuts and bolts you removed previously. Remove the locking pliers or clamp from the center bracket.[10]
Received all items as indicated, I would recommend purchasing a metal center bearing also, other Than the plastic that this comes with. Install was easy and strait forward. hardest part was finding how many turns to tighten those springs?? I used a general rule of thumb of a full turn for every ft. Of door. 4 quarter turns equals 1 full turn. I found that 26 balanced the door perfectly. These springs seem a little smaller than what was there however, the coil itself is the same. (Pic) After installing, I recommend oiling the springs with some motor oil. This will help with rust and noise. Good luck with yours, it's worth the work for the saving!!
Next, check to see if your garage door operator is the problem. Do this by pulling the emergency release cord when the door is in the down position (so the door doesn’t come crashing down in case there is a problem). Then, try to lift the door up manually. Does it open easily? If so, your opener is probably at fault. If it still doesn’t move, the problem likely lies with your tracks, springs, or rollers.
NEVER use screwdrivers, pin punches or pliers handles to wind or unwind a torsion spring. Trust us: This is the best way to wind up in the hospital. Don't even think about doing this job without a proper set of winding bars. You can buy a set of professional hardened-steel winding bars for about $25 from online suppliers. (Garagedoorpartsusa.com and stardoorparts.com are two online sources that sell winding bars, springs and other parts.) Professional winding bars work with 1/2-in. and 7/16-in. winding cones. If your winding cones have 1/2-in. openings, you can make your own winding bars by cutting a 36-in. length of 1/2-in.-diameter round bar stock in half (buy round bar stock from any hardware or home center). Just file a smooth bevel on each end so it slides into the winding cone holes easier.
There could be a few issues that might be causing your transmitters not to work properly. The most common reason could be that you’re simply out of range of your garage door. Each garage door and transmitter combo has a specific range it will function in. If you’re trying to open your garage door before you can even see your house, then chances are you’re just too far away. Try waiting until you turn into your driveway to hit your transmitter button, and you should have more success opening your garage door on the first try.
Can you find what you need in the big home improvement stores? Can they show you how to fix a broken garage spring? Do they know what tools and replacement parts you need? Do they know what safety precautions you need to take? If you have any questions during the project, can you call them for help? Have they ever actually repaired a broken garage door spring themselves?

Slide the left spring onto the tube and add the cable drum. When your new springs arrive, put the new left spring (the 1 with the end facing up and to the left) on the torsion tube, making sure that the stationary cone on the end of the spring faces the center bracket. After sliding the new spring into place, replace the cable drum and insert the torsion bar into the left bearing bracket.[9]
There’s nothing more frustrating than attempting to open or close your garage door only to find that it simply won’t budge. In some cases, your garage door may even open or close halfway only to get stuck in the process. The very first thing that you should do if your garage door seems to be stuck is to check the batteries in your remote. You’d be surprised at how often this is the root of the trouble. If dead batteries were not the issue, then use the following four tips to further troubleshoot your garage door.
Thread the cables and tighten the drums. Run the lift cable between the roller and the doorjamb. Slip the lift cable stop through the cable slot on the drum. Then, attach locking pliers to the torsion tube to secure it in place. Spin the drum to wind the cable into the grooves, then tighten the set screws. Repeat on the other side, leaving the locking pliers in place.[11]

11.1 Many torsion spring replacement accidents occur from springs that are too strong. If the garage door stays on the floor by itself, remove the vise grip from the track. If the door is off the floor and the roller is against the vise grip, close the door with one hand and remove the vise grip with the other. If the springs are too strong, you have to restrain it from flying into the open position.

Just like car tires are rated by miles, garage door springs are rated by an estimated number of cycles (1 cycle = your garage door going up AND down 1 time). The springs used by our competition range anywhere from 5,000-10,000 cycles, whereas we use a high-grade steel spring rated for 25,000-50,000 cycles! This is why we can put, in most cases, a Lifetime Guarantee on our springs for as long as you live in your home!

Garage door springs don’t require extensive care and maintenance. However, they also can’t be left entirely to their own devices. Spraying the springs with WD-40 is a good place to start. It’s also a good idea to check the balance of the garage door every year. To do this, simply lift the garage door up about halfway and let go. If the springs are in good working condition, the door should remain still. If the springs are beginning to weaken, the door might sag or fall. By taking these basic steps, you can preserve your door springs for longer.
Does your garage door seem to be jammed? There are several reasons this could have happened.

This is an easy fix by realizing this problem and then unlocking your garage door. rong.

Replacing a garage door panel can add significantly to the cost of a garage door repair. Panels run horizontally on sectional roll-up garage doors. They may be made of wood, vinyl, aluminum, fiberglass or steel. Garage door panels can become damaged from hail and other extreme weather, dents and dings, car accidents, and age. When deciding if you want to replace a garage door panel, it’s helpful to compare the potential repair cost to the cost of a new garage door. Panel replacement requires a pro with the proper tools as well as the new parts. With parts and labor you could be paying more than $500 for one new panel. In comparison, a new garage door may cost $800-$1,200 (on average) with installation. If there is a possibility your garage door was structurally compromised when the panel was damaged, have the pro assess whether it’s better to completely remove and replace the door, rails and framework to ensure your home’s safety. It may also be better to completely replace your door if it is severely rusted or dented; if the paint is peeling and fading; if the door model is outdated or you can’t find replacement panels; or if the panels or rails are structurally compromised.
Step 1: Check the metal tracks inside the garage. Look at the mounting brackets that hold the tracks to the walls. If they're loose, tighten the bolts or screws at the brackets. Working inside the garage with the garage door closed, examine the tracks for dents, crimps, or flat spots. If there are any damaged spots, pound them out with a rubber mallet, or with a hammer and a block of scrap wood. If the tracks are badly damaged, they should be replaced.
Overhead garage doors weigh hundreds of pounds, and doors that are not properly maintained or which are equipped with older automatic garage door openers can be safety time bombs. All too common are the tragic stories of garage doors injuring or even killing children or pets who found themselves underneath a closing door. Modern automatic door openers with auto-stop and auto-reverse mechanisms have greatly reduced such accidents, but mishaps can still occur if the door and door opener are not properly maintained.
Widths - in addition to doors coming in a range of styles, they can be found as double-width and single-width styles. There are some serious considerations when opting for one over the other. For example, if a homeowner decides to use a single door that covers the entire opening of a two-car garage they will have to make serious structural modifications to the entry way;
9.4 Slide the end of the shaft into the end bearing plate. Tighten the set screws an additional 1/4 to 1/2 turns beyond the point you finger-tightened them. Add an additional 1/4 turn if you could not find the original set screw indentations in the previous step. Heavier wooden garage doors may require an additional 1/4 turn. Caution: Under-tightening the drums could cause the drum to slip and the door to cock or fall. Over-tightening the set screws could damage the shaft or drum, resulting in the same problems. This is a critical step.
Both types of springs are loaded, or under tension, when the door is closed. This gives them stored energy to help lift the door as it's being opened. When the door is all the way up, the springs are relaxed, or relatively so—they still may be under some tension. The mechanical difference between extension and torsion springs is that extension springs are loaded by stretching, or elongating, while torsion springs are loaded by twisting, creating torque.
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.
Delivered on time, with the products described: springs, winding bats, & plastic bushing. Quick install, but apparently I measured wrong, so these total length I bought was larger (which is good as there is less stress on the spring). However this did mean that I needed more than the generic rule of 30 1/4-turns of preload. I wound up with 38 1/4-turns per side for the door to balance when open 3' (per familyhandyman.com recommendations). Would definitely do it again.
6.8 Properly tightened screws will loosen with less than a turn. Once you loosen a set screw, keep at least one bar in the cone AT ALL TIMES until the spring is fully unwound. Many cones have been over-tightened. The spring may unwind 1/4 turn and not unwind any more until one of the set screws is loosened some more. You may need to completely remove the set screws. The shaft may be distorted and the cone still may not unwind at all.
If you are in an emergency situation, you can lift the door manually while using the garage door opener, but this is not recommended. The door could get stuck halfway up and then slam the rest of the way down. This could cause injury. The ideal solution is to call a Twin Cities garage door repair company to come quickly and repair the spring so that normal operation can be restored and so you are not in a situation where you find yourself having to attempt manual lift with or without the assistance of the opener.
Sectional: Also known as a raised panel door, this door is the most common. It is made of several horizontal panels hinged together, fitted with wheels and mounted within a track. The biggest advantage of this door is it takes up relatively little space and easily controlled with a standard remote garage door opener for a nominal cost. Their moving parts are readily accessible which can keep repair costs low. The average cost for sectional door repairs is $128.
