Egg Beater has a warranty program to upgrade old pedals. They will exchange your early model Egg Beaters with a new pair of the current, much improved model. There is a $25 per pair charge. I just got my FIVE pair exchanged. The new ones are supposed to be easier to rebuild. Call or email If your pedals have the rubber dust cap that pops out to access the screw, you have the old original model. The new ones have a screw in aluminum dust cap and disassemble with a nut.
