How do I fix an external roller shutter that does not open all the way?

Hello,
I have a problem with external roller shutters which are about 10 years old and were purchased with the house.
The cassettes of these roller shutters are in the house above the window.
The problem is that the roller blind does not open all the way.
I have got into the cassette and I can see there that the end of this roller that it winds up on from the side opposite the motor just flies.
I am posting pictures and a video to illustrate.
1. can anyone tell me what I have damaged? is it the part in the tube or the whole side?
2. what parts should I buy to fix this? What are they expertly called?
3. how do I remove the hangers from the beam without damaging anything? smofy hangers 1780759
To start with, I want to remove the motor pulley to look at it carefully but I don't know how to go about removing these hangers.

I guess it's a matter of adjusting the motor's limiters.

The shaft appears horizontal, so the stops need to be adjusted. How? This depends on the motors used.
However, this play should not be present. The shaft hub should be fixed on a bearing that has probably come out of the sideplate or the sideplate(bearing mount) is damaged. The hangers act as a so-called "Triticum" and the easiest way to remove them is to move some of the white rings outwards then the Triticum will slide out of the holder.
Then slide the plastic hub(retainer) into the octagonal tube to get the clearance needed to remove the shaft.
The motor is also probably attached to the other side. You will also need to dismantle/unscrew/remove this mount (depending on the type of engine). Then, after disconnecting the wires, the motor, together with the shaft and hub, should "come out".

Thanks mate. I'll be dismantling it today and will ask you some more details if necessary. I already have some suspicion of what happened there, but I need to be 100% sure and I'll paste pictures once I've mounted everything.

I forgot to add that the hub/holder can be secured against sliding into the shaft. In most cases this is a rivet connecting the hub to the shaft.

My colleague, in this case, the rivet was cut and the winding tube shaft holder entered the tube and pulled the bearing out of the seat.
If I am going to rivet it later, is one rivet sufficient, as everyone shows on the videos, or should I rivet it in two places?

i have a fi 60 pipe and i need to buy a good bearing and a good holder so i don't have to look in there for at least 3 years
is this some kind of standard or do I have to measure something to buy a bearing and housing?



despite wondering in the video I want to replace the bearing and housing because there is play on the shaft and the bearing itself also has play

this is what the bearing seat looks like i think it is ok and a set to buy

The bearing should go into the side quite tightly. You don't have to buy a new bearing and retainer. There will also be play in the new components. This is typical of these roller shutter components. It is unlikely that the rivet will cut itself. It is likely that the roller shutter was repaired in the past and the hub was not riveted. As a rule, one rivet is sufficient. I do not use rivets but rather tight screws. It can happen, for example, that the motor is damaged and the rivet is on the non-visible side of the shaft....

Are you suggesting putting it together on what I have? Just secure with a rivet or a screw? What gives you that it will be a screw on the invisible side AND not a rivet?

I put one together on the old parts and so far it's working. The only problem is that it opens halfway. How do I set the stops on it? Motor as shown in the photo and additionally controlled by the module from the photo A elmes STX remote control. Is it possible to do this from a remote control or a switch? I don't have access to the taps.

Yes.

Your choice. You will remove the screw with a small screwdriver or bit and try to ream out the rivet when you only have a few inches of space...

You have a Simu T5E 8/17 motor model.Google the manual.

With the remote control no, using a locking louvre switch is unlikely either....

Mate with this googling of this French product is not so easy and yesterday I spent some time on it.
The only thing I found that could fit is the one in the attachment, but I have my doubts because at the top of the manual is the number 5013732D and on my motor is 5051526A.
Either way I am guessing that I need to buy some kind of special switch to program the limiters if I want to do it myself only:
1. is it definitely the switch given in the instructions that I need ?
2. does the fact that the roller shutter only opens 1/3 up and closes normally give me 100% certainty that this only requires adjustment of the stops or could it still be something to do with the motor?

I have a total of 9 roller shutters so the switch will pay for itself after one service.

Note that the switch used to adjust the limiters is actually two bell buttons connected to the phase of the input, unlike louvre systems where it is mechanically or electrically blocked to apply phase to both directions of rotation simultaneously. So why would you want to buy a service cable with a switch????

This question can only be answered by a fortune teller, but I would start with adjusting the rocker arms as this is the easiest and does not generate costs.

thanks a lot mate. I will buy two bell buttons and check. I thought this was just a simplified diagram and maybe there is something else sitting inside such a button, as it costs about 50-60 euros.

And will you tell me just out of curiosity why it might have gone out of tune?

There could be several reasons for this. From accidental phase application to both directions (entering programming mode), through increased resistance of the roller shutter (these motors have obstacle detection) to damage to the motor/internal controller.

And could this increased drag be that the bearing fell out of the seat and the whole winding tube fell down one end?
For example, could these side guides also be dirty enough after 10 years that this too is doing the extra drag?

I've also noticed that it now goes down as if a bit abrupt and kind of crooked on this side. It's also noisier on the side with the bearing.
.

More likely there is a symptom/sound somewhere of the roller shutter mantle hooking on the housing or slide. You'll need to take a close look while it's running.

Mate, and what you can see in the video I am pasting now suggests something?
The roller blind opens up to what you can see and then goes back down a bit on its own.
After several openings and closings it doesn't even open halfway to the window.

.

It seems that the obstacle detection has worked. If there is nothing blocking the movement of the roller shutter (it may be obstructing somewhere, as evidenced by the previous video) then try helping it up by pushing it slightly from below and observe the effect.

Well I just thought about that detection too, but I didn't want to suggest anything to you. I've pushed it from underneath before and it blocked too. Am I thinking correctly to undo the hangers and see how the tube itself goes without the roller shutter?

You can try. Also see what the sensitivity is by slowly clamping your hand on the shaft.
If the shaft rotates without any problem, let it rotate in the lowering direction until it stops by itself. Then put the hangers back on.

Thanks for the advice I will be fiddling with this on Thursday or Friday to have to go away on business. I won't let go of this roller shutter I'll let you know what came out

Mate Marek I managed to get the two roller shutters fixed today. I hung them on the old bearings, reset the motor settings and set the limiters. The only thing I noticed was that when I cleaned the brushes in the guides with a liquid, it improved the quality of the roller shutters. The brushes were the cause of the roller blind going down either going abruptly or stopping and you could see that it was unrolling in the cassette.
Could you tell me, just from experience, if there are any preparations to make these brushes have a better glide? I can see that they are stiff and a bit dull. Is there any easy way to replace these brushes? I noticed in one roller shutter that one brush is missing.

Can these brushes be replaced somehow easily?

It used to be that rubber was also used in the guides and was permanently crimped into the guide (aluminium guides). Now there are both versions (in PVC guides I think it's just the "brushes"). They can be easily replaced if they are not crimped into the guide or glued (without gluing they easily slip out on their own and can block the roller shutter armour), but access on an assembled roller shutter is difficult as they have to be removed and new ones inserted from above or below.

It's not easy to change the brushes here though, I've already looked into it. It looks like the guides are fixed under the polystyrene and I would have to destroy the facade to change the brushes.
However, I have a problem with one roller shutter. When I programmed it, it kept going until I used the remote control and let it go down or up. As soon as I pressed the 3rd STOP button and stopped it loses the setting and will no longer go up to the maximum. It will reach half way up the window, stop and drop down a bit and only that is its final position. Any idea what this could be and how to fix it ?
