The sleeves provide a very generous bearing surface. Rather than enlarge their inner diameter, would it be better to shorten the sleeves?
I think someone should try this first & let me know how they get on.

They're only 3mm long and quite hard, so a bit tricky to hold while you're cutting them (or boring them out like I suggested doing with a clock brooch, so I gave up). You could replace them with a ring of brass 1mm long or less.

I'm now thinking about folding up some thin sheet brass to form a U around the axles to replace the middle axle sleeve bearings and held in with the plastic keeper. But unless you're looking very closely to see the lateral wheel wobbles, removing the bearing sleeves from the middle axle completely and bending the pickups away so they don't touch the wheels and just running like that is fine. The old sloppy hole principle from the early days of compensation.
