Removing DMR V12 bushes ?

Last week or so, someone said it was possible to remove and replace the bushes on these pedals, so I dragged mine out of the scrap box and set to, but I was unable to find a seam in the bush, and it resisted my desperate bashing 🙁 What I don’t understand is, the rebuild kit includes an outboard bearing and a new axle, but no bush, despite this being the most serious wear item (together with the mating surface on the axle)

Has anyone any tips on removing the bush ?
