Hi, I have a problem with a mower that performs well so far as in the title. The visual inspection shows that the rotor bearing has probably collapsed. How to remove the pulley in this configuration? Is it hammered? Screw in? Any tips are appreciated :)

The wheel is screwed in. The thread is probably right, i.e. unscrewing to the left. Hold the impeller towards the fan. Link

Thanks for the tips! After unscrewing the pulley, the plastic of the fan should be gently lifted, then down the hill - two long screws, removing the brush holders and the whole business on top :) Two bearings 6001z and 627z scattered inside.
