['LIVEWIRE?']

Here are some pictures of the upper and lower deck and the cam gear. I have tried to locate the cam correctly with the deck in both the loaded and ejected positions without success, and don't really want to remove the cassette carrier unless I have to. Maybe I'm missing something but, IMHO, if the cam gear can be removed without dismantling other parts, it should be possible to refit it with the other parts in situ. Correct me if I'm wrong, folks! Unfortunately I don't know how the timing marks on the cam gear and the pinch roller drive gear should be relative to each other. My main problem seems to be locating the projection on the bottom of the cassette carrier into the right slot in the cam gear!
