garage door issues


-I have a 2-door garage doow with a single torsion bar above.
cables came loose. noticed pulley too close to support so had to move it. Have tried to tighten cables but they still stay loose.
Does this mean the torsion bar needs to be adjusted (not by me) or is there some trick to tightening the cables?
Had new torsion bar installed 3 years ago and replaced opener six months ago. (FYI)
Noticed that door must be rubbing occasionally against support edge of wall. (FYI)

Most torsion bars for double doors have two coikled springs one on each side ot the center supporting bracket. There are pulleys on each end of the torsion bar, when the dooor is fully up, the pulleys fill up with the lifting cables and reduce the tension on the spring.. But even with the door fully up, there should be a little tension on the lifting cables to hold the door up (as if there were no connection to the door opener)
Find a neighbor with a similar type of torsion bar installation, they are quite common, and study and learn how they work, then you can look at your situation and figure things out. This is not rocket science, but basic homeownership 101.

Hmm, didn't notice OP's handle till you mentioned it. No relation that I am aware of. Sorting the stack by name doesn't show any other posts by them (not curious enough to google them), so I assume they are a newbie or something.

Spraying the springs with cosmoline or similar will go a long way to keep them functional. Biggest reason for failure is micro-corrosion giving the crack a place to start. Better springs are usually painted or given a coating to reduce this tendency. Your replacement charge was a tat high, but probably in line for the area.

Yes, but as already stated by yourself and others, DON"T mess with the torsion bar. One of those things put a friend and his adult son in the hospital several years ago. My Friend lost his thumb.
