Accord slow speed stuck

[stroller]

I have a moore unidrill with an accord type seed metering mechanism, I’ve pulled out the red slow speed cog but I can't push it back again. It is lined up with the indents in the cog behind but won't move at all, gentle persuasion with a socket and hammer won't shift it either. Any ideas?

Wd40 in between the cogs, and try easing it back and forth, from memory theres a wee springy ballbearing thing in there that can stick.

Done the wd, it’s always been a bit stiff

I still haven't moved it, what happens if I take the circlip off and pull the cog off the shaft?
