Hope this is the right section for this.

According to Philco's Service Bulletin #273, they refer to a lock pin that holds the pinion gear and shaft in. The instructions state to place a wood block on the side with the pin and to rap the block sharply to get the pin out.

Well, that confuses me.

Am I to assume that the pin is supposed to back out on it's own? 

I'm not sure because it appears to be pressed in. 

Any help would be greatly appreciated.
