Garage Pulley 3 in. Heavy Duty Pulley for Extension Spring

This is a 3″ Garage Pulley that includes a 3/8″ hole. Pulleys are a vital part in making your extension spring garage door open and close properly. A working garage pulley will roll smoothly with no jerking, pulling or shifting on the track. Each high-quality garage pulley has a weight capacity of up to 200 pounds and can handle up to 25,000 cycles for an 8 ft door. These pulleys are made from a heavier gauge than standard pulleys. Because of this, the weight capacity and cycle life are higher. It is recommended that you change your pulleys anytime you change your extension springs. Because the process is relatively painless, you shouldn’t mind this at all. Check out our video below to learn more about the process and see how easy it is to get started. You enjoy the benefits of an upgraded pulley and improve your overall safety and security of your garage door.

Why should you replace a Garage Pulley?

When a garage door fails to open and close properly, the cause is often a worn garage pulley. Maybe the garage door opens halfway and either stops or closes. If you hear a scraping noise, that could be a worn ball bearing is causing the pulley to grind the track angle. If the door binds or sticks, that could be the result of a split pulley caused by a failed rivet. If your garage door jerks or shifts from side to side, you probably need new pulleys. To determine if the pulleys are worn, it’s important to take the spring tension off of the pulleys and cables first. To relieve tension, open the garage door, which will remove nearly all of the tension from the extension spring. Use vise grips on the track to hold the door up and prevent it from falling back down. Then wiggle the garage pulley to see if it has a lot of movement from side to side. You can also check for loose ball bearings by shaking them. Make sure they turn smoothly, and check for bearing wear by twisting them while they’re bolted to the pulley fork or track.
