I did not loosen the chain tensioner (since the wheel is floating), I moved the rollers themselves relative to the gear wheel, the upper lock was installed and screwed to the housing. Down - the shaft was based on the blockade. The gear wheel is screwed tight with the lock in place. You think it may be a mistake that the tensioner was not released - what does it matter if we do not change the position of the chain relative to the sprockets. It seems to me that the tensioner is only released when the chain is replaced, am I wrong?

About these axes what you write - this is the position of the rollers relative to each other, but this is actually determined by the upper blockade of the rollers - as it is installed, there is no other option - I will take photos and attach it just to be sure.
