Out of curiosity, why are you disassembling the freewheel in the first place? Replacements are generally cheap enough that it's not worth rebuilding them.
If you're trying to remove the freewheel to service the wheel hub bearings, then you're going at it all wrong. You need a freewheel removal tool and a big adjustable wrench and the entire freewheel will come off as a unit.
