5 Best Garage Torsion Spring Replacement Steps
Here are the five best steps for replacing a garage door torsion spring, with a strong emphasis on safety. While DIY replacement is possible, it is hazardous due to the high tension in springs—always consider hiring a professional if unsure.^1
1. Preparation and Safety First
- Disconnect the garage door opener and ensure the door is fully closed.
- Gather safety gear (gloves, glasses) and required tools (winding bars, wrench, ladder, etc.).
- Clamp the door and shaft in place to prevent accidental movement.^3
2. Unwind the Old Springs
- Insert a winding bar into the winding cone on the torsion spring.
- Loosen the set screws carefully with a wrench and let the tension off the spring, lowering the bar gradually.
- Alternate bars in and out of the cone, unwinding the spring in small increments until fully relaxed.^4
3. Remove Torsion Spring and Hardware
- Loosen the bolts on the cable drums and set the cables aside.
- Slide the shaft sideways to access and remove the old springs, as well as inspect and replace bearings if necessary.^4
- Remove the old springs and inspect/clean the shaft.
4. Install New Torsion Springs
- Slide the new spring(s) onto the shaft, ensuring correct orientation (right/left wind).
- Secure springs to the center bracket and reinstall cable drums, making sure cables are taut and correctly seated in drum grooves.^3
5. Wind New Springs and Test
- Use winding bars, carefully add the recommended number of turns per manufacturer.
- Tighten set screws and gently remove winding bars.
- Reattach opener, test door balance manually, and check operation. Adjust spring tension if needed for smooth, balanced movement.^1
