Proper Cotter press is not a cheap tool, but I expect any decent shop in CPH
has that tool to do the job
though a pin punch and a hammer are low cost.


if mangled you have to buy new cotters anyhow.
You are aware that there is some hand filing the taper on the cotter ,
for best fit, right?

BTW, the fork looks bent, like it hit something.. blades have a reverse curve.
