Mamiya C330 film wind crank problem

Hi everyone,

I’ve a Mamiya C330 and the film wind crank at one point slows down then it does its job again how it should. Also I realized that if I do not wind the crank very slowly sometimes it could wind 2 frames instead of 1. I’ve only found one video on youtube but it’s about a stucked wind crank and as I’m not sure if that solution would solve mine as well I did not want to follow those instructions. Has anyone experienced this before and if yes what was the outcome/solution? Would some lubrication solve the problem or is it something else as well?

Kind regards,

Laci

One of my c220 also goes over a frame if I don’t pay extra attention.

But I can’t help you. I’ll try to open my c220 one day, shouldn’t be a difficult fix.

Did you check the multiable exposure knob beside the winder handle?
I assume you have the pressure plate set to 120 and not 220.
