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.

Sorry. I have the lock ring off on the left, non-drive side,
and am left with an adjustable cup that will only turn
partway. The fixed cup is still in place too (on the other
side), so the spindle is in place and blocks putting in the
bolt and nut that Sheldon describes.

For what it's worth, the fixed cup also seems to be pretty
stuck. It's an aluminum frame, so presumably the shell is
aluminum too and there may be some corrosion in the interface
between the two different metals of the shell and the cups?

if you search on aluminum/steel frame/shells/cups install or
remove there should be an avalanche of umbrage.

if your system shows white material in joints then poss an
ionic binding occurred between steel and aluminum. Andy Muzi is
an expert on this.

Blaster does not dissolve the white material. Uneeda torch and
another pin tool.

expanding aluminum with torch or heat gun will remove the cup.

Okay, I will try heating too.

try utube on heating with propane torch

small flame, cone above steel, wave flame around ext of where cup is
located inside, go around around slowly at 90 degrees if poss, with all
the other tools on hand.....have a vise ? place pin tool in vise n rotate
frame...wuhwuhwuh....

heat the steel until the grease inside the BB smakes a bt...keep an eye
on that...when smokes then slowly turn in one direction just a budge then
back then forward again...you hope...then back repeating.

Hot enough to make the grease smoke has probably ruined the temper of the
steel.

It may be worth considering sacrifice the bearing cup anyway - its cheaper
and easier to replace than the frame.

gnaw .....800 is a warm summer's day in Steelville.

propane doesn't turn steel from everday steel color to a different heat color tho there is increased oxidation prob nearing 800.....that is very visual.

oxidation tends to double every 10 degrees.

I dunno aluminum ...thin aluminum wrinkles but the expansion rate is greater.
