Hi I am just assembling a yamacha model from lego technic no 42159 and I have a problem assembling the gearbox. The instructions show that the letters F and G on part no 6447081 should be perfectly aligned however I am not able to do that. I am attaching pictures and please give me some hint.
I cant upload photos directly here so there is a link to imgur https://imgur.com/a/XF7gNOF
