(My current adventure began with F04 tape loading error. I'm now deep into Panasonic K Mechanism alignment (AG-5710/1980.)
I'm seriously thinking my Pinch Cam is misaligned or not assembled correctly. I've yet to discover a video or written explanation in any detail of this aspect of the Panasonic K Mechanism.
Symptom: the pinch roller doesn't go up and down properly AFAIK. When I turn the pinch cam gear, it doesn't go up/down even though I see the plastic spiral. I can manually move it up/down a little by lifting/turning... yet even that seems inadequate.
Progress:
- I've removed the pinch roller assembly from the top of the pinch cam.
- I've now got the inner gear+spiral axle (white plastic), and outer yellowish plastic housing that apparently should ride up and down the spiral.
Problem: while the outer housing is loose, it absolutely will not lift off of the inner gear/spiral.
QUESTIONS:- Any pointers to descriptive info / video on how this ought to function?
- Any ideas on disassembly?
Thanks muchly!
