I've pulled the cranks and the lock ring on the left side, but
the adjustable cup won't come out. It turns about a quarter
turn, but then gets too stiff to turn further. It has no
flats for a wrench instead having holes for turning with a pin
spanner--so I'm unable to put a lot of force on it.

I've soaked it with WD40, but still no joy. Any advice for

Have you had any luck getting that cup off or looser?

Check Sheldon's Tool Tips again because he tells you whether to tighten the inside or the outside of the bolt-nut tool.For what it's worth I found that it took a lot of presure to tighten the nut/bolt to the point where it'd unscrew the cup and when it did it was a very sudden movement of the cup.

Good luck and cheers
