A difficult one because both brass parts are bonded into plastic.

One solution would be to machine away the original bush and fit a new one. Alternatively bore out the bush, press in a sleeve and then ream the sleeve's internal diameter to suit the shaft. I have no idea though whether the case could take the machining forces.

I've seen worn shafts knurled to increase their diameter then turned down to suit a bush,
