[Shop-talk] De-coupling overhead door torsion spring

[DAVID MASSEY]

 If you have seen it done it would be obvious but if you haven't maybe watching this video will help.

He is tensioning the spring here and what you want to do is the reverse but the technique is the same.  The bolts to loosen are the ones that secure the end of the spring to the shaft but make sure you stick a rod in the hole first.  

Remember, there is a lot of stored energy in that spring.  If you don't feel confident, get professional help.

Which bolts am I loosening, Bill? The ones that appear to hold to the shaft the fixture I'm going to be inserting the riffs into?
Thanks.

Scott -
De-tension the springs first. You will need two steel rods, 12” - 18” long. 3/8” socket extensions work well. 
Put one rod into the hole in the collar with the securing bolts in it. Hold on to the rod when you loosen the bolts, and use the two rods to relieve the spring tension, 1/4 turn at a time.

Got a new insulated garage door for winter here. Need to remove the old door.


Torsion springs seem to be one of those things that drive emergency room visits in real life, not just internet clickbait.


Before I just do what Google says, I think I'd like to hear from the real people on a subject like that. Can I somehow un-do the cable ends from the door, or the cables from the springs and then remove the door panels, or do I need to de-tension the torsion spring first?


And if I need to de-tension it, what's the best method to avoid smashed skulls or broken limbs?


Thanks in advance.
