Yes all 125/151/176 ccm have the same clutch.
Say, LIKE, DINK, AGILITY, GRAND DINK/YAGER.
Check up on all of it and send me a list what you need, goes at once then.
BTW: pics look to me as only the big (39mm) nut would have gone off...
..could be reassambled, if nothing broke or missing
EDIT: looking closer at this thread pic #2 and #3 and analyzing, I would see (from marks)that, it had been removed before and not properly tighened then. For the skidmarks at the threads rim I would say, repairable with a tap-file.
Indestines of your clutch have to be checked, particularely resistance coil and sleeve with warts(sliders). Balance of clutchbell too.
So don't rush with a new clutch.
