Normally the cable comes back from the spring and is attached to the track as shown in yellow.
You have reels (red) shown in the second picture that are used to easily adjust the tension on the springs.
I have never seen them before but they are just tension adjustment spools.... doubtful they'd ever go bad.
You are looking for replacement pulleys... by the brown arrow.... correct ? 3" garage door replacement pulleys
Tks for the reply.
I cant seem to find these anywhere on the internet either.
Not the pulley bearing that is shot. The shaft that comes out of the tensioner/drum is very crooked. points down and back towards spring. So the bearing inside that plastic housing OR the seat where the inner end of the shaft bearing sits is shot.
Tomorrow I will try to contact the company that supplied the building materials for my garage.
Those are Clopay ez set extension spring doors sold at a lumber yard. see example here Put the door up take the cable off the pulley and try to tighten the nut with a 9/16 socket in an impact. I also notice your top sections aren't braced and openers look to be mounted too high above the door... should be about 12-13 inches
Ok.... I misunderstood.
That black item is just a tensioner. It doesn't turn as the door moves.
That shaft is strictly for adjusting the cable tension.
craftsman 1/2 hp chain has been operating at least 5 years no issues. probably more. i have a 2 car single heavy segmented wood door but it's been doing it perfectly all these years. i know its out of balance because during power outages its very hard to lift up manually
i wanted battery backup so have a chamberlain belt drive 3/4 hp belt drive lv5000 i think is the model. it lifted up the door about 6 inches then stopped and started to drop the door. never saw anything like that before.
called chamberlain and they said it's because out of balance. she wanted me to do a balance test and i told her how heavy it was.
i have 3 holes where the side springs attach the the tracks. currently the S hook is on the center one. i opened the door and clamped it and i tried the closer to the door spot and fell off a ladder so that wasnt fun. lotta pull required on that spring! but i did it. still it woudlnt open. then just for the FUN of it, i tried the hole farthest from the door. no dice. so i give up. gotta call a pro in monday. access is very tight and no way could i adjust the cables by unscrewing them etc . but what bugs me even more is long time ago a spring broke and when the guy installed a new one. he obviously didnt balance the doors and i was clueless back then to ask.
the girl on the company line said because of the new technology, the door wont open when it's so heavy and out of balance. to me this makes zero sense. the 1/2 worked fine the past few years. why wouldnt a new one 3/4 work even better? certainly if i overheated the motor every time it would have burned up years ago right?

My garage door just before it fully closes is rubbing against the side door frame near the top. There is a brace as pictured running horizontally across the top and bottom of the entire door.
Each end of each brace has a nut to tighten or loosen the brace.
The hinge mounts and the structure of the door all seem tight.
Can I tighten or loosen the nuts to move the door away from where it is rubbing?
How do I go about this without making my problem worse?
Thanks!
