- DO NOT attempt to install or adjust springs if you are not experienced with garage door repair.
- ALWAYS wear appropriate safety gear, including safety glasses and heavy-duty gloves.
- NEVER remove or replace springs while the garage door is open or under tension.
- ENSURE all spring tension is released before attempting to weigh the door or remove components.

- CONSULT a professional if you are unsure about any step or procedure.
3. Identifying Your Torquemaster Spring System
Before ordering or installing a replacement spring, it is essential to correctly identify whether your garage door uses a Torquemaster Original (TM TMI) or Torquemaster Plus (TMII TM3) system. The primary difference lies in the winding end of the spring.

This image illustrates the visual differences between the winding ends of the Torquemaster Plus and Torquemaster Original spring systems. The Torquemaster Plus (top) typically has a hexagonal winding end, while the Torquemaster Original (bottom) features external splines with a rounded end. Identifying your system correctly is crucial for ordering the right replacement spring.
The Torquemaster Original system (TM TMI) typically has a counter gear visible on the outside of the bracket. The winding end of the spring for this system features external splines with a rounded end. In contrast, the Torquemaster Plus system (TMII TM3) usually has a visible spring cone sticking out of the bracket and a hexagonal winding end.

This video from Express Garage Doors Inc. guides you through the essential steps to correctly identify your Wayne Dalton Torquemaster spring type, measure your garage door's height, and determine its weight. These details are critical for ordering the appropriate replacement spring.
4. Measuring Your Garage Door
4.1 Door Height
To determine the correct spring, measure the height of your garage door. Alternatively, check the label on the spring tube, which often lists the door dimensions.
- For doors measuring between 6'6" and 7'5", select a 7 ft high spring.
- For doors measuring between 7'6" and 8'5", select an 8 ft high spring.
4.2 Door Weight
The balance weight of your garage door is critical for selecting the correct spring. This information is usually found on a label located on the metal spring tube. If the weight is not listed, you can measure it using a bathroom scale:
- Ensure all spring tension is released before proceeding.
- Lift the garage door slightly and slide a bathroom scale under the center of the door.
- Lower the door onto the scale, ensuring the full weight of the door is on the scale.
- Verify that both cables are completely slack. If there is still tension in the cables, the weight reading will not be accurate.
- Record the weight and select the spring weight range that your door's weight falls within.
Selecting a spring with a higher or lower weight rating than your actual door weight may result in improper door operation or premature spring failure.
5. Installation Instructions
A detailed installation reference manual is included with your Wayne Dalton Torquemaster spring. It is imperative to read and understand all instructions and safety warnings in that manual before attempting any installation. Due to the high tension involved with garage door springs, improper installation can lead to severe injury or damage. If you are not confident in your ability to safely install the spring, please contact a qualified garage door professional.
6. Operation
Once correctly installed, the Torquemaster spring system assists in balancing the weight of your garage door, allowing it to open and close smoothly with minimal effort. The spring stores mechanical energy when the door is closed and releases it to lift the door. A properly balanced door should remain stationary when stopped at any point during its travel.
7. Maintenance
Regular maintenance can extend the life of your garage door spring system. It is recommended to:
- Inspect the spring and associated hardware periodically for signs of wear, rust, or damage.
- Keep the spring and moving parts clean and free of debris.
- Avoid applying lubricants to the spring coils, as this can attract dirt and reduce friction needed for proper operation. Lubricate only specified moving parts as per your garage door opener manual.
- Ensure the door is balanced. If the door does not stay open at various heights, the spring may need adjustment or replacement.
WARNING: Do not attempt to adjust spring tension yourself unless you are a trained professional. Spring adjustments involve high tension and can be extremely dangerous.
8. Troubleshooting
If your garage door is not operating correctly, consider the following common issues related to the spring system:
- Door feels heavy or won't stay open: This indicates insufficient spring tension or a broken spring.
- Loud bang from the garage: This is a common sign of a broken spring.
- Door opens too quickly: This suggests too much spring tension.
- Cables appear loose or frayed: This could be due to a broken spring or issues with the cable drums.
For any of these issues, it is strongly recommended to contact a qualified garage door technician for inspection and repair. Do not attempt to operate the garage door with a broken or improperly tensioned spring.
