Adjusting a garage door ?

post #1 of 10
Thread Starter 
My garage door is a little "sticky", it is not nearly a smoothe as it once was. I can see that when it is fully closed there is a small gap on the left side at the bottom, maybe 1/2". Is there any tricks to get it to run smoothe again ?
Do I try to adjust the rollers on the door or the runners that the door rolls in ?

Thanks

First question is, does your door have two springs? Or one?

Two springs.

Okay, K , then the adjustment you need to make is on the cable that runs by the spring on the side of the door that touches the ground first. Your door is unbalanced.
It's an easy fix.
The cables attach at one end to the bottom of the door, up over a pulley, then thru another pulley held with a clevis to the spring, and then to a fixed point. At or near this fixed point there should be some type of adjustment fixture/hardware. What it is depends on the type of door and manufacturer.
What you need to do is raise the door as high as you can (higher than it normally rests), and then clamp a good sized pair of vise grips onto the track to hold the door up into this position.
Now the springs aren't under load, and you can safely tighten/adjust the cable to take up the difference in the balance of the door. It may be a small adjustment, or it may take a few tries, but this is the way it should be done.

Also, if you have an automatic opener, you must disconnect the door from it. And unplug it lest someone hit the button while you are working on it and cause great problems,cussing, and or harm . Usually this is done by removing a pin from a swinging arm that attaches the opener track to the door.

How did you make out?

Ben,
I replaced both springs a few months ago and have the same problem.
I will try this fix this week end.
Thanks

Be VERY, VERY carefull tightening the springs! A buddy of mine ended up with a few HUNDRED stitches in his forearm when the rod used to tighten the springs slipped and the spring whipped around like a buzz saw.

Jerry, that musta ben a center spring.
And there are easy safety steps to take before attempting that job.

i almost lost half my face this past spring when trying to get the bottom wheel back on the track. i decided that it would be easier to unbolt the entire wheel assembly while the door was down, instead of holding my arms over my head. well, the first four bolts came out without a problem. however, when that last bolt came out, that spring pulled the entire bracket with the wheel past my face with some major force. i could feel it brush past my cheek and ear, and then heard it slam into the garage door itself. there is now a nice gouge where the bracket hit the door. anyhow, this was a lesson learned. think before you act.

now yesterday when i had to rebuild most of the one side of my garage door, i opened the door all the way, held it up with some boards, and then disconnected the cable which goes thru the pulley on the end of the spring. it was much nicer that way. i just wish i had read this posting about six months ago.

doyle, I'm glad yer okay, man.
This is why ya gotta have the door open and tension off the spring, if yer gonna adjust it.
I'd strongly suggest a large pair of vise grips clamped tightly to the track to prevent the door moving rather than a board that could possibly be kicked out by an unsuspecting "helper"
