Hello Gundars,

here I can give you some links with more information:

1) picture with parts of the clutch:

2) in many articles you can find pictures and explanations: go to Suche with the word Zapfwellenkupplung or Kupplung

in example: https://www.trac-technik.de/Forum/showth...?tid=15327&page=5

with: http://up.picr.de/10426260jq.jpg

I think it is very difficult to give general informations about the clutch of the PTO.
If you can give us a concrete problem or precise question normally someone in the Forum would probably help.

Best regards
Franz Josef
