I have a garador garage door (20 years old) one of the springs has broken
and I have purchased a set of pre loaded springs, before I fit this how can
I safely release the tension from the unbroken spring in order to retrieve
the cable, instructions from the internet suggest just snip this one however
I want to save it without doing this. It is attached at the lower end on to
an elongated C clip with a groove where the cable end should be able to slip
out...IF I can control the tension.
Any help appreciated.
It is an up and over door with the springs located in a metal box horizontal
above the door fixed to the door frame.
If I remember correctly, there is a hook around 3 inches away from the
attachment point of the existing spring. You attach something with a
hooked end over the spring end, pull it to release it from its anchor
point, then hook it over the hooked point on the frame. It is a little
awkward, but isnt too bad. It helps if you have someone handy with a
long screwdriver, as I found the hardest bit was getting the released
end over the frame point to get it held. You dont release all of the
tension when doing this.
To reply by e-mail, change the ' + ' to 'plus'.
There is a flat metal tag mounted on top of the pulley which engages in
a slot in the top of the metal box. I have only done this with the box
removed from the garage and secured in a vice. I think the initial
release was by gripping the cable with a Mole wrench (should this item
be added to the list headed by angle grinder?) creating some slack by
pulling the wire with a gloved hand and releasing the loop from the door
Once secured in a vice (use a suitable bolt through the top securing
mount and grip that in the vice jaws) the cable can be pulled with a
metal bar through the loop. You need an assistant to engage the tag.
How have they *pre-tensioned the springs*?
You only get one shot at re-fitting so it pays to have an assistant
standing by to stop the tag re-engaging the slot as you try to release
the spring. The cable is very keen to jump out of the pulley groove so
try to pull the cable towards the door frame rather than into the
garage. Use GLOVES!
