How to reset garage cable back into groove wheel?

[bawbster]

Cable came off the grooved pulley wheel(?) and the garage hook kicked in to stop it from falling few days ago, managed to close the door until I could get a better look at it, seen that the cable was off tne wheel. Opened the door fully and the cable went back onto the wheel by itself, only thing is, is that the cable doesn't sit into the groove properly. The door opens and close, just a little stiff and you can hear the cable rolling over itself. Want to try and fix it (if its easy enough) incase it wears outthe cable.
Any help on this one?
cheers

I appreciate that this is a diy site, but…

I had an old door do this and did manage to do it myself, although way too long ago to remember. I had an old mate help me. If things go wrong, it goes with a bang.
I would ring a local garage door repair guy. It won’t take long.

Can you take the tension out the cable?
You can buy new cables and parts so it should be fixable.

So watched a few videos and they say lock with mole grips but with different doors to mine, then seen this video

with same make (no windows on mine though) with same spring and cog layout. Guy in the video doesn't use mole grips to secure it though. Will give it a go in a few weeks when i'm off for a few days, don't have mole grips but is it worth purchasing them to help with it even though this guy doesn't use them?

I don't know.
I did watch a bit and looks easy enough.
Just get stuck in and you will learn as you go. Save a packet as they say...
Mole grips are cheap and always worth having a pair if you are doing DIY.

If you move the door slowly and completely to the other position does it unwind the cable enough to take out the misalignment ? Can you post a video?

Can you take a longer shot of the bar leading into the pulley (to ascertain whether there are any sprocket holes as per the video example and/or nut for spanner connection) if so we can take it from there? If not then its a case of mole grips and lap of Gods

If the cable's jumping out of the groove perhaps the pulley wheel isn't rotating freely. Have you tried lubricating its bearing?

My mechanism slightly different from yours , can't make out how your door pivots open but probably not to dissimilar from mine.
When I had an issue with mine I used a couple of metal rods located in the holes as per photo and a spanner on the adjacent nut and basically wound the spring loaded shaft backwards in a leap frogging type small turns action using either the rods or spanner to rotate it. and when the cable had slacked off enough moved it round into the correct grooves. Since you don't have a nut it looks like you will have to use moles grips which may slip?

I was hoping for a movie of the drum the cable is wound onto, how it behaves when the door is cycled fully open and then fully closed

Spring end has multiple holes that two rods can walk, no?

OP before you take any action with the spring take a note of how many turns of the spring your door has when the spring is fully loaded (door closed)
You can assess this by looking at the painted line on the spring. It's not fully visible in your pictures, but count the number of turns of the painted spiral before you release the spring tension. You'll need to tension it back up to that amount or thereabouts when putting it back (when the spring releases it will uncoil and the painted spiral will have fewer turns)

usually find mechanism hidden by door as soon as you start to raise it hence photos taken whilst door shut?

Appears not, same as mine, a couple of pairs at 180 spacing, but useful for holding the tensioned spring in place as mole grips (or in may case spanner) moved round for positioning for next small rotation.

Anything like my rust covered spring of 30 years there will be no visible line but of no consequence as the tension on the shaft is not released but increased slightly as you try and take the tension off the cable around the spool so it can be repositioned in the correct grooves (unless you let shaft slip and the spring totally unwinds and then we are into a slightly different scenario of having to retention the entire spring)
