I had a feeling there wasn't a good solution apart from buying a replacement. Definitely a shame. Thanks for the response!

Hi everyone,

I've just got into photography and borrowed my friend's camera for a month to have a play around. He lent me his old Pentax P30, which was working fine. But then half way through a film roll the wind lever (also known as advance lever maybe?) went very loose. It is not engaging at all now.

I was struggling to find instructions on how to tighten it. Online, it seems there are a lot of similar issues coming up. Could anyone help here at all?

It would save me from having to buy another camera for my friend!:/
