Olympus OM-4 film advance problem

<p>Hello,<br>

film advance only works, when I'm very careful and stop at a certain point right before the end. If I use the advance lever normally, I can't press the release button, but I can use the advance lever over and over again.<br>

This video shows my problem clearly:<br>

I've been told that at the end of the transport, the first curtain is supposed to be held. But it doesn't work, because the detend (?) doesn't lock. <br>

I've been told that I won't need any spare parts, but how can i fix it???<br>

Thank you, Kai</p>

This is a common problem in OM-2S, 3, 3Ti, 4, 4T and 4Ti. I still see a lot of them for repair.
