garage door not parallel to the floor

[mcgyverit]

Had a torsion spring break on my double garage door. as you are standing inside the garage, it would be on the right side of center. Just so happens that the right side is lower by about 1" when compared to the floor and the header. and when closed there is a gap on the left side.

on the very end of the steel tube that the springs are clamped to, is the pulley with the cable that attaches to the bottom of the door. what I am guessing is that when I put the pulley back on I didn't get the cable tight on the pulley as needed and then with the weight of the door it has stretch allowing the door to be lower on the right than the left.

so my question is, couldn't I clamp the door in place in the down position, loosen the pulley on the tube, crank the pulley around to help lift the door up the amount that I need and then tighten the 2 bolts back on the tubing?

while the tubing has the tension on it, it really cant go anywhere since the left side is still tied to the door, correct?

or if possible, do all this in the up position?

With the door "up", you can't access the torsion springs.

If I am understanding you correctly, I would remove tension from the other spring, position the door / cables properly, then retension both springs.

took care of this today.

elevated the door slightly to get a jack under it.
clamped it in two places on the left side so it couldn't move.
marked a reference line on the right side and jacked it up slightly to take the tension out of the cable on the pulley.
loosened the pulley's 2 bolts and then rotated the pulley to take the slack out of the cable.
undid all the clamps and lowered it and now the right side was higher than the left. repeat the process and lowered it accordingly and it came out perfect.
much better.

I really didn't want to have to mess with those springs again, but I did make some pins for the adjustment in case I had to from some steel rod.

Good to see a followup, with good results.
