I've drilled a 3/16" hole on the opposite side of the spider gear cross pin down to the level of the broken-off pin, and used the point of an awl to work the pin out of the hole. Once the end of the pin is exposed, a piece of stiff wire like a clothes hanger can be bent and forced into the hole to keep the pin moving. The hole doesn't weaken the carrier in any way.
