Played around with loosening screws, no real change. I'll just put it back together (carefully) tomorrow. I still don't have the motivation to sleeve anything.
Interesting point about the new version of the motor plate. I'd noticed before that there was a 1.5mm recess cut into the motor side. What I didn't notice was the 1.6mm shaved off of the spur gear boss, thus necessitating the 1.6mm spacer behind the spur gear. Interesting, but why?
Perhaps because they still insist on the user setting the pinion on the motor with their old plastic contraption which would give the wrong pinion protrusion given the motor recess isn't there any more hence you have to bring the spur out by the same amount.
