When converting the older Crawford garage doors with outside lift cable drums and bottom fixtures to standard torsion spring systems, or when replacing springs on low headroom doors with outside lift hardware, you will need to make the following changes that differ from replacing standard garage door torsion springs.
- Reverse the end bearing plates. If you are replacing these, so the race of the bearing is against the side of the drum opposite the setscrews.
- Secure the center support bracket with two screws on top and one on the bottom.
- Install the right wind spring with red paint on the winding cone on the right side of the bracket. Then, install the left wind spring with black paint on the winding cone on the left side of the bracket.
- Vise grip the shaft from the bottom and rest it against the top of the door instead of on top of the shaft and against the header or drywall.
- Install the cable drum with the black paint to the right of the end bearing plate. It should be on the right side of the right end bearing plate. Then, install the drum with red paint on the left side of the left end bearing plate.
- Wrap both cables around the fronts of the drums instead of the backs of the drums, as pictured above.
- Wind both springs down instead of up.
