If you're 100% sure that there's no binding, bent screw or bent outdrive then you can try the following:
Get your 37t pulley in your hand - see the little 'nobs' that stick out in between each hole? get a sharp scalpel (a bendy one works best) and carefully cut each of these off. Hupo won the Euros so I beleive what he says - and the friction of these on the plates can undo the diff sometimes. Don't worry I thought he was on something as well - but I've done it ever since and I've never had a diff come loose since.
The 'nobs' stop the pulley wobbling about - but it doesn't really matter if it wobbles about.
Usually it's the thrust race though - when you build it make sure you put the face with the lowest brass insert toward the outside (the head of the screw). This is so the screw sits on the plate of the thrust race rather than the insert. Also make sure you grease the race with black grease or antiwear grease.
