Torsion Spring Cone Replacement - DDM Garage Doors
The next step is to reinstall the cones in the springs. This can be done in a vise, but I have always found it easier to do this with the springs and cones on the shaft. To install, the cones, begin by turning each spring onto the cones by hand. Next, grip the 4th, 5th, 6th, and 7th coils from each end with the pipe wrench or large channel locks.
