Monos 15 - External roller shutter motor replacement (how to remove from the housing)?

Welcome,

I have decided to replace my external roller shutter motor. I won't describe the problem as it's a bezel one. I intend to purchase a new one.

The problem occurred when removing the old motor.
I unwound the roller shutter and unbolted it from the metal motor housing. I removed one screw and reamed out two rivets. I can freely move the housing by several mm to the left or right. Unfortunately I have no idea how to unbolt the motor housing. I've tried gently undermining the plastic blanket (the one on the end adjustment side) so that it somehow comes off, but it doesn't do anything, and I don't want to do it by force lest I kick something over. I understand that you first pull the tip off the left side (engine side). I really don't understand the way it is attached. I would be grateful for your help.

On the engine housing I was able to read: "Model/Type: Monos 15 Made by Italy". Unfortunately I have not found any information on the internet about how to pull such a motor.

Ps. Of course I do all the work
I attach photos

Hello.
Maybe a topic already out of date, but it may be useful to others.
Firstly, you need to detach the hangers that connect the tube to the roller shutter shell. There are sort of anchor-shaped hooks. Turn them about 45 degrees and pull them out of the rectangular holes in the shaft.
Secondly, check that the motor, specifically the drive end, is not riveted / screwed to the shaft (depending on the length of the motor, this is at a distance of approx. 40-80 cm from the side. You should be able to see the protruding end of a rivet or screw on the shaft. It may not be visible from the back of the shaft. The rivet should be drilled out or the screw removed.
Thirdly, on the opposite side of the shaft, there is a hub/shoulder which should be a few centimetres longer than the shaft itself and should also be screwed/riveted at one or more points to the shaft. The above should be unscrewed/riveted. After this operation, the hub should be able to slide into the shaft causing it to be released from the bearing. This clearance should be sufficient to pull the shaft with the motor out of the motor mount (there may be some pins which need to be removed. Cut/disconnect the cable from the motor beforehand.
Remove the entire shaft with motor, pull the motor out of the shaft and already....
Assemble in reverse order (of course, remember to set the limit switches)
