Hi all,

I have an early 1990s Rodriguez tandem with a rear bottom bracket
in serious need of overhaul. The cranks flop severely.

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 me?

If your unit is a cup rather than a cartridge then tghis do it
yourself tool from Sheldon Brown (RIP) works wonders.

It's towards the bottom of the page under "Fixed-Cup Tools".

Thanks guys, but I need to get the adjustable cup off before I
could use Sheldon's tool on the fixed cup.

Ted, I don't quite follow. You are talking about using a pin spanner and then say that you need to get the adjustable cup off first. Isn't that what we were talking about? The lock nut on the adjustable side and the fixed cup do not use pin spanners as far as I know.
