Thanks for this Gadge that confirm what i was thinking this axial play is the problem.
I bought a new bearing today and actually the old one was rusty but still in good operation order but I'll still change it to be sure
I also order a spacer to compensate for the wear. So i will rebuild the clutch when i got it and let you know.
Cheers
