It looks to me as though I need to remove the hex socket Allen screw from the centre of the AEG 86741 Lavamat pulley so that I can take off the pulley to replace the bearings but it is so tight that I have snapped the hex key in trying.
Does it have a left-hand thread or is there some secret or tool for the job, please?

Thank you CK. That is very helpful. We have now got the pulley off. Do we need to push the drum shaft forward to enable us to lever the bearings out of the plastic outer drum or do we need to actually take back of the outer drum out of the machine?

yes they are tight due to loctite.secret is to hit the hex allen key bolt hard a few times to loosen then undo with an allen key fitted to a ratchet.DON'T damage bolt hitting it.just shock it to break loctite
