I think the dearth of information may spring from the fact that backlash often isn't checked. I've never done it. May be best practices to check it every time, but - - -. We rely on the sizing of the gears, and the wear or lack of it on the aluminum gear. And if both are from the same motor, put them back in and don't worry. Nothing you can do to adjust anyway, short of getting different gears.

Porsche used to have a system where you could mix and match marked gears to get it where it should be. I think they gave up on this, and only sell one universal set? Something like that.
