How to Replace Your Garage Door’s Extension Spring Pulley

Steps to Replacing Your Extension Spring Pulley

Do you have an extension spring garage door? Chances are you do since most are. These doors use cables and pulleys to open and close the door, and the door itself tend to last longer than the springs. However, the exposed elements of these doors, including the pulleys, are at a high risk of damage. Here’s how you can tell if your pulley is in need of replacement, and what  the replacement entails.

How to Tell If Your Extension Spring Pulley Needs Replacement

Garage door spring pulley repair and service

If your garage door is an extension spring garage door, and the pulley breaks, then the garage door will stop part of the way when you are trying to open the door. This typically will cause a high-pitched screeching noise as well as the problems opening and closing. If you notice these two problems, take a look at the pulley and cables, and see if there is a pulley that looks broken. Most of the time the damage occurs when the ball bearings wear out.


How to Replace an Extension Spring Pulley
Extension spring pulley replacement is dangerous and is best handled by a professional or someone who has extensive experience working with garage doors. As you read the steps below, remember that you are always safer to call a professional if you have any doubt about your abilities to handle the job safely.

To begin, ensure the garage door is closed, then unplug the garage door opener and disengage it with the emergency release cord. Open the door manually to the point where you can’t open it, but don’t force it past this point and make the problem worse. Use a piece of wood or some other item that can stabilize the door to prop it open to this point.

Next, check that the cables connected to the pulleys are slack. Then remove the cable clip from the s-hook, which will remove the cable from the pulley. The pulley is connected to the track with a bolt. Remove this bolt and remove the pulley. Install the new pulley and fasten it as the old one was. Reattach everything, and check to see if the door opens manually or not. If it does, restore power and re-engage the door.

Remember, however, that this may sound easy, but it’s actually very dangerous. Extension springs can break and fly at you, causing serious injury. If you feel that you would like a professional to tackle this job for you, contact the ASSA ABLOY team a call today.
