My mistake!
I didn't catch the long arm pulley cage in your first picture or the parts breakdown.
That's a Cyclone GT model which came out in late 1975. My descriptions of capacities refer to the short arm original version. I'm going to leave them posted because the info may help someone else.
Side note, aside from cleaning and re-greasing the pulleys, I've only taken apart a few Suntour rear derailleurs. My Cyclones have never needed more than that.
BITD (1970's) Suntour RDs were so cheap (inexpensive) that few ever bothered working on them, it was easier to just replace them.
Suntour V short arm RDs sold form ~$6.00 retail and the long arm versions sold for ~$7.00! (as opposed to Campy Nuovo Record RDs that went for $29-$39).
Good luck with your project.
