If you see the splined ends showing through the crank was pressed onto the spindle from the right. If you see what appears to be the rim of a flange, the spindle was pressed through the arm from the right the same as the one in the photo I linked.
It's non-removable as far as I can tell. - Wait, whoa.. Okay, just discovered how the bolt is attached, a small bit of 10mm over the 8mm hex slot. Clever. The bolt, not me.
So, brilliant, it looks like the failure happened mainly in the bolt itself. Which shouldn't be too hard to find. I'll have to report back on the state of the spindle threads, perhaps they aren't as stripped as they seem. Thought all that debris was spindle shavings - but the bolt is aluminium. I might have been wrong about the robustness of this gear.
Cheers for the help!
