Let me be honest with you if you do not have the expertise to deal with these problems or even notice either of these signs, it’s important to call a professional to fix the problem. Ignoring it could result in further damage to your garage door or even injury if it breaks because springs are under tremendous tension.

if you detected one of these signs that we mentioned above you must start thinking about replacing your garage door spring because ignoring the issue will make everything more complicated and potentially harmful to you or your property. So these steps are mandentory for you on how to do it by yourself.

1- Know the strengths of your garage door spring

Garage door torsion & extension springs come in a variety of strengths and picking the right one depends on the weight of your door, the old spring diameter, the inside diameter & spring type.

Generally, they’re color-coded is the easiest identification to know your garage door spring strength. here you can see we have 10 springs color codes. Remember that this way of identification is not the most accurate way and you will probably have errors in your measurements of your spring strength.

As experts, we always use the 20 coils measurements method while measuring the torsion spring diameter, which is listed below in Replace Torsion Spring section step 4 point 6 or you can read our article about how to choose your garage door springs. which is important if you are planning to else buy replacement springs.

We won’t encourage you to do any replacements for your garage door springs by yourself, as we always mention that springs are not meant to be a DIY project because it could be dangerous and cause harm to your property or yourself if you do not have the proper knowledge of the dynamics of garage door systems.

The ends of each spring are colored white for the lightest and Tan for the heaviest some other companies use blue for both their 90-pound and 140-pound Springs. If your existing Springs are blue it’s a good idea to double-check either your door weight. take a look at your existing Springs if they are color-coded make sure you replace them with Springs of the same color.


2- Know the different types of garage door springs

Knowing your garage door spring type is important to get the right replacement. There are two types of garage door springs Torsion springs and extension springs.

  • Torsion springs are located above the door.
  • Extension springs are located on either side of the door.

Both types of springs are important in the operation of your garage door. Torsion springs provide the power to open and close your garage door.

They are wound tightly and when released, unwind and provide the force needed to lift the door. Extension springs provide balance and support as the door opens and closes.

They help to counterbalance the weight of the door and keep it from slamming shut. It is important to know which type of spring your garage door is to ensure that it is repaired or replaced properly.

A qualified garage door technician will be able to determine which type of spring your door has and make the necessary repairs.

Types Of Torsion Springs

  • Standard torsion springs are most commonly found on residential garage doors – usually, only one spring is needed for effective operation on lighter doors.
  • Early-set torsion springs are similar to standard torsion springs, except that they are mounted in the middle of the torsion shaft and they are one of the safest springs because are situated inside the shaft.
  • Steel rolling-door torsion springs are more likely to be seen in commercial and industrial buildings. It’s like any other spring but These springs are contained within the torsion barrel.
  • Torque-master torsion springs are spring systems developed by Wayne Dalton garage doors they are enclosed in the torsion shaft and held in place by a winding cone at the end of each torsion rod.

Types of Extension Springs

  • Open-looped extension springs are the weakest style of extension spring and rely on one open wire at the end.
  • Double-looped extension springs are stronger than open-looped, featuring two coils at the end of the spring connect next to the pulley and eyebolt.
  • Clipped-end extension springs this kind of extension springs are the best option, they tend to last longer and are frequently used on garage doors that weigh more than 200 lbs.

Safety first: Lock down the door

Before beginning any garage door parts replacement or repair, be sure to unplug the garage door opener to avoid any injuries And Keep the garage door closed while replacing torsion springs.

Find the wheel attached to your garage door that travels in the track.Then, tighten the C clamp in the track directly above the wheel.

This will prevent further accidents from happening.

Screwdrivers, pin punches, and pliers handles should never be used to wind or unwind a torsion spring.

If you’re thinking about doing this job without a proper set of winding bars, just don’t!.

Professional winding bars work with 1/2-inch. and 7/16-in. winding cones.Unplug your garage door opener before beginning this project, and be sure to keep it unplugged throughout.

C-Clamp to lock the garage door

Use The Winding Bar

In order to loosen the unbroken spring, use the winding bar.Look for the bottom hole of the winding cone of the good spring and shove the winding bar inside.Once the bar is in place, hold it while loosening the two setscrews. Be careful – when you release the setscrews, the spring will try to push with a lot of force.

Remove the springs, cables, and cable drums

To insert the second winding bar, insert it into the hole at the 9:00 position.
Remove the bottom bar and unwind the spring a quarter turn at a time. As you unwind, make sure to switch between the winding bars.

Use C-clamp to Secure the torsion tube.

You will need to snap a C-clamp onto the center bracket in order to hold the torsion tube securely in place within the bracket.
Next, loosen the setscrews on both the left and right lift cable drums before disconnecting the lift cables from each drum.

Remove the springs from the bracket.

first, disconnect them from the stationary spring cones. Then remove the two nuts and bolts that fasten the spring cones to the center bracket. Finally, slide the springs toward the end brackets.

Replacement Spring

  1. there are a few pieces of information you have to know about the garage door spring ( The Spring wire diameter – The Inside Wire diameter – For Torsion spring Length is needed – Left or right-hand Wind Spring ).
    Calculate the wire diameter
    To calculate the wire diameter of the garage door spring, you will need to have a calculator and tape measure then use the 20 coils measurements method. For example, if you have a spring Count of 20 coils and the length of these 20 Coils is 5 inches then you can calculate the wire diameter by dividing 5 inches by 20. So in this case, the wire diameter would be 250.Another example: is if the coils measure 6.44 inches, the wire diameter would be 20/6.44 = 322. As you can see, even a small difference in coil size can make a big difference in the wire diameter. That’s why it’s important to be precise when measuring coils.A good way to confirm your wire diameter measurement is to count the number of coils and then divide it by 40. This way, you’re double-checking your work and eliminating any potential errors.The Spring color code systems we listed above can also be used to figure out wire diameter measurements, though it’s important to note that there are two different code systems in use and one of them is not very accurate anymore.
    The Inside Wire Diameter To Know the inside wire diameter you will find them written on the winding cones of the spring.
    Torsion spring Length: On your broken spring you will take the measurement of the first piece then you will measure the second one and add both measurements together to get the length of the spring.Tips: If you measure 3/4 of an inch longer or shorter it won’t make any difference to your garage door balance, but do not add the size of the winding cones of the spring that’s would make a lot more different and may result in throwing off your garage door from the track.Left or right-hand Spring: Simply look in the direction of the spring and see does the spring start clockwise or counterclockwise if it’s clockwise so it’s a right-hand spring and if it’s counterclockwise so it’s a left-hand spring.

Replace the torsion spring

To replace a torsion spring, start by sliding the new spring onto the torsion tube with the stationary cone facing the center bracket. Then, reinstall the cable drum with the garage door wire. Finally, reinsert the torsion into the left-side bearing bracket.

Install the torsion bar

first shove it to the left, then slide on the center bearing. Install the right spring, and then push the bearing into the stationary cone. Finally, reinstall the drum. Once the drum is in place, connect both stationary cones to the center bracket.

Run the lift cables inside the cable drum.

by putting the lift cables in the cable slot until it reaches the lift cable stop point. Slide the lift cable stop through the slot on the cable drum.

Tighten the drums.

use locking pliers onto the torsion tube, and rotate the drum to wind the cable into the winding grooves.
Pull the cable as tight as possible before tightening the setscrews and leave the locking pliers in place and repeat the tightening procedure on the other side. equal tension on both sides is required so that the door opens evenly.

Start winding the spring toward the ceiling

by the wind bars the regular recommendation is to do 30-quarter turns for a 7-foot tall garage door or 36-quarter turns for an 8-foot tall garage door. Before tightening the setscrews, tap the winding bar to expand the spring out from the center about 1/4 inch. Rotate the setscrews until they come into contact with the torsion tube. Then turn the screws one-half to three-quarters turn tighter.

The Last Step Is to Lubricate the spring

Lubrication is really important for your garage door metal parts. In general, the best option is to lubricate your garage door with PTEF lubrication because it dry fast and doesn’t attracts dirt. perfect if you living in a dusty or tropical area or if your garage is your workplace.

Silicone-based lubrication or lithium-based lubrication is recommended for long-lasting lubrication and rust protection.

Some people use WD-40 but it’s not the best practice because WD-40 Is a degreaser that in fact works as a lubrication cleaner, Instead Use WD-40 Specialist.

Read this article for more information on the best garage door lubrication products.

Finally, lubricate all the hinges in your garage door and clean all the rollers at the edge of the door then lubricate them as well.

Don’t Lubricate plastic parts with lubrication that is not indicate it’s safe for plastic and rubbers. Super slick slick stuff Lubrication is recommended.

How Replace Extension Springs

at both the left and the right side of your garage door track. Make sure you tighten your C-clamp because it will work as a safety precaution to prevent your garage door from closing.


Remove the attached parts to the spring

Your extension spring is attracted to 3 parts ( pulley – safety cable – Eyebolt [S HOOK] ). Each part will be removed in order to remove the springs.

Remove the pulley

The extension spring is attached to the pulley so you first need to remove that pulley by using the crescent wrench to loosen the bolt on the pulley. Make sure to retain the pulley orientation to make sure which way to pull it back up and attach it to your new extension springs.

Untie the steel safety cable

The safety cable is passing through the extension spring and is attached to a bracket that usually comes off your ceiling. Now Untie the safety cable and remove it from the pulley. Always remember to not make your safety cable unwound or check if it’s already unwounded or damaged and needs to be replaced too.

Remove the spring from the Eyebolt

Your old spring is almost removed. After you untied the safety cable and pulled it out through the extension spring, you should see that it’s just hanging from that eye bolt and now you can remove the spring from the eyebolt.

Eyebolt (S-Hook)

Put your new extension spring un-colored end to the Eyebolt

Hook the uncolored end of the new extension spring onto the eyebolt and then stretch the spring to attach the colored end to the pulley system.

Put the safety cable clamp back & Slide the safety cable

To reattach the safety cable clamp, first, slide the cable through the center of the clamp and then position the clamp on the end of the extension spring. Use pliers to tighten the clamp onto the spring, making sure it is securely attached. Finally, wrap the safety cable around the securing bolt or eyebolt and use pliers to tighten it into place.

Slide the pulley back in it's place

Slide the pulley back in its place in the safety cable clamp and tighten up the nut and bolt. Your pulley wheel & steel cable in the pulley should be on the right side of your safety cable.

Your new extension springs installed

Now after you finished replacing your new extension springs it’s time to re-attach your garage door to the opener & remove your C-clamps and take your ladder then plug your opener back into electricity.
