The other type of assembly connects
the springs to cables which run through pulleys and connect to
the door (as illustrated below).
Wear safety glasses to protect your
eyes from the possibility of a spring firing into your face. Close
the door to reduce the tension on the springs. Replace one spring
at a time before moving on to the next.
Attempt to lift the spring's hook
from its anchor point with your fingers. If the tension is too
great, try using the shaft of a medium/large screwdriver. Place
the shaft into the hook and pull down on the hook and lift it
off of its anchor. If necessary, find a leverage point for the
screwdriver and pry the spring off. Unhook
the spring from its other anchor point and install the new spring.
If you are replacing the cables
or pulleys, first remove the springs. The cables connect to the
door in a variety of different ways. Inspect the connector on
the replacement cables to help you understand how they fasten
to the door. The pulleys are typically held in place with one
or two screws and are easily replaced.
