I tried to clean my exhaust fan. Everything went well and I was able to remove the engine from the holder in order to clean it.
However, some parts were stuck together, so I tried to remove them. It took a bit of time and force, but I was able to remove the nut from the bolt.
However, first it didn’t change anything and then, it didn’t even come apart. I also noticed I broke a little black thingy and I don’t know what it is useful for. And now, I am not able to put the nut on the bolt..
I don’t care about cleaning, I just want to put it back now..
