Change axe cuffs?

The other day, when I was under the Hondi, I had to find out with horror that my axe cuffs were both torn in the middle. 8 -O tja shit because without cuffs no TÜV. Now I want to buy the parts cheaply and install them myself. Now the question to you: Can I do this without special tools at all. Do not want to disassemble the thing and then realize that I don’t have to come any further and screw all the shit together again. and what do I have to pay special attention to??? Thank you
