1. Introduction and Safety Information
This manual provides essential instructions for the safe handling, installation, and maintenance of your G.A.S Hardware 225x2x25 garage door torsion spring. Please read all instructions carefully before proceeding with any steps. Garage door springs are under extreme tension and can cause serious injury or death if not handled properly. Professional installation is highly recommended. If you are not experienced with garage door spring replacement, consult a qualified technician.
Safety Precautions:
- Always wear appropriate personal protective equipment, including safety glasses and heavy-duty gloves.
- Ensure the garage door is fully open and secured before beginning any work.
- Never attempt to remove or adjust a torsion spring without proper winding bars.
- Keep children and pets away from the work area.
- Do not stand directly in front of the spring when winding or unwinding.

3. Important Pre-Installation Considerations
Before replacing your garage door torsion spring, it is crucial to ensure you have the correct replacement spring. Incorrect spring selection can lead to improper door balance, damage to the opener, or safety hazards.
3.1. Identifying Spring Side (Right vs. Left)
Torsion springs are designated as either 'Right Wind' or 'Left Wind' based on their coil direction and cone color. This product is a 'Right Side' spring, indicated by a Black Cone. When facing the garage door from the inside of the garage:
- Right Side Spring (Black Cone): Coiled counter-clockwise. Installed on the right side of the center bearing plate.
- Left Side Spring (Red Cone): Coiled clockwise. Installed on the left side of the center bearing plate.

3.2. Measuring Your Existing Spring
Accurate measurement of your existing spring is critical. The three key measurements are wire size, inside diameter, and length. This spring is 225x2x25, meaning:
- Wire Size: 0.225 inches (measured by counting 20 coils and dividing by 20).
- Inside Diameter: 2 inches (measured from the inside edge of the spring coil).
- Length: 25 inches (measured from one end of the coils to the other, excluding the cones).

Ensure these measurements match your existing spring for proper function and safety.
4. Setup and Installation
WARNING: Garage door spring replacement is a dangerous task. If you are not confident in your ability to safely perform this procedure, please contact a professional garage door technician. Improper installation can result in severe injury or property damage.
This section provides a general overview. Always refer to detailed safety videos and guides before attempting installation.
- Prepare the Work Area: Close the garage door completely. Unplug the garage door opener. Secure the door in the closed position with C-clamps or vice grips on the vertical tracks just above the rollers.
- Release Old Spring Tension: Carefully insert a winding bar into the bottom winding cone hole of the old spring. Hold it firmly. Loosen the set screws on the winding cone. Slowly and carefully unwind the spring, one quarter turn at a time, using both winding bars. Alternate bars, keeping one firmly in place while repositioning the other.
- Remove Old Spring: Once all tension is released, remove the winding cone from the shaft. Loosen the set screws on the stationary cone (center bearing plate) and slide the old spring off the torsion shaft. Remove the old center bearing and end bearing if replacing.
- Install New Spring: Slide the new G.A.S Hardware torsion spring onto the torsion shaft. Ensure the black cone (winding cone) is facing the correct direction (towards the end plate for a right-side spring). Install the new 1" steel bearing. Secure the stationary cone to the center bearing plate.
- Wind the New Spring: This is the most critical and dangerous step. Consult your garage door manufacturer's specifications for the correct number of turns for your door height. Insert a winding bar into the bottom hole of the winding cone. Wind the spring upwards (counter-clockwise for a right-side spring), one quarter turn at a time. After each quarter turn, insert the second winding bar into the next available hole to hold the tension, then remove the first bar and repeat. Ensure the set screws on the winding cone are tightened securely after winding.
- Test and Adjust: Carefully remove the clamps and plug in the opener. Test the door's balance. If the door is too heavy (falls quickly) or too light (flies up), adjust the spring tension by adding or removing quarter turns as needed.
5. Operation
The torsion spring system is designed to counterbalance the weight of your garage door, making it easy to open and close manually or with an automatic opener. When the door closes, the springs wind up, storing energy. When the door opens, the springs unwind, releasing energy to assist in lifting the door.
Your G.A.S Hardware torsion spring features a precision E-coating for smooth and quiet operation, contributing to an effortless lifting and lowering experience.

6. Maintenance
Your G.A.S Hardware torsion spring is designed for minimal maintenance due to its advanced features:
- Precision E-Coating: The electrophoretic coating provides excellent corrosion and abrasion resistance, eliminating the need for lubrication. This keeps your hands clean during installation and inspection.
- Regular Visual Inspection: Periodically inspect the spring for any visible signs of wear, rust, or damage. Check for loose winding cone set screws. If any issues are observed, contact a professional.
- Door Balance Check: Annually, disconnect your garage door opener and manually lift the door halfway. It should stay in place without assistance. If it falls or rises, the spring tension may need adjustment by a qualified technician.

7. Troubleshooting Common Issues
If your garage door is not operating correctly after spring replacement, consider the following:
- Door is Heavy or Falls Quickly: The spring may be under-wound. This requires adding more turns to the spring. Do not attempt if inexperienced.
- Door Flies Up or Does Not Stay Down: The spring may be over-wound. This requires removing turns from the spring. Do not attempt if inexperienced.
- Unusual Noises: Check for any obstructions in the tracks or around the spring. Ensure all fasteners are tight. The E-coating on your G.A.S Hardware spring is designed to minimize noise.
- Door Jerks or Sticks: Inspect rollers, tracks, and cables for damage or misalignment. Ensure the torsion shaft is properly aligned and the bearings are functioning smoothly.
For any persistent issues or if you suspect a broken component, contact a professional garage door service technician.
