I really like the clear instructions that Vaionaut has given in the previous post. Could someone do something like this for whatever is the best solution for the Lego 42113 gears issue(s)? I have looked at this entire thread but I don't understand the fixes that seem so clear to others. People talk about things like a 20z something and I have no idea what 20z means, for example. Ideally, if someone could provide simple instructions like the kind that comes with any lego set, that an 11 year old could follow easily, I think it would do a world of good for everyone. It would also be great if there were some parts numbers for ordering purposes. Thanks in advance.
