I have a similar problem but on a 221K "Featherweight". Both the motor and the pulley are bakelite and I've tried two nights of putting Kroil around the area where the shaft goes through the Bakelite pulley (being careful it can't run towards the motor windings etc). I could (with a lot of patience and in tiny increments) get the other shaft out of its end but the pulley end doesn't want to budge. I've completely removed the screw that goes through it into the shaft and, as near as I can tell, this shaft doesn't have the "flat spot" like US-made motors.
Does anyone have some more ideas on how I might get it off without shattering the bakelite on either the motor or the pulley, please? I'm afraid of prying/twisting under the pulley with a screwdriver (or two - to even out the pressure) as I know these are renowned for being brittle and it only takes a split second for it to be too late.
Thanks in advance for any help or tips anyone can give.
