DKW RT 125/2 chain stigma

Good day, dear MOTOR-TALK community, does one of you know which puller I need for the chain scribbling of the primary chain, i.e. the one on the crankshaft? Basically, I just want to change the primary chain, as individual sleeve links were broken. In a workshop manual there is something of a puller no. 08515, that would be an M22x1.5. But when I measured roughly with the measuring slide, I came to 25,2 mm – now I am a bit overburdened. hrauber solve. Or does someone have a better idea how to do this more skillfully? I would be very grateful about links to counterholders or special tools!
