So, to reassemble it.
There is a bit of a conundrum with the rotor. The small gear won't go through the bearing. So the sequence is to install the bearing in the housing - it's held in with a triangular plate - then press the rotor into the inner while fitting the gear over the end. No doubt on production they had all sorts of jigs and presses, but I was more lump of wood, suitable sized socket and medium hammer. I was a bit nervous about it 'cause I'd had a lot of trouble getting the bearing inner off, but it went back OK. I guess it's all arranged with the right tolerances, and the case is strong enough to stand the push. A dose of Loctite here and there made me feel better. It all turned freely so I redistributed the grease and put it mostly back together.
Next the brushes. Actually they were relatively easy, just the Fastons were a very tight to push on to what appeared to be very flimsy Males.
Finally, reassemble the handle - it rotates and test it. Lo, it works. It has some sort of Soft Start built in, not surprising as it's 2kW, which is a bit disconcerting at first. You squeeze the trigger, nothing happens then it winds up. At first it sounded a bit rattly, but it's OK now. I don't expect to give it the hammer it got before, but as a ten quid backup it's not bad
