Spoggy, I've wondered that same thing many times. Hell, I even know an old time machine shop that can cut gears (in case Graingers or McMaster doesn't have it). Truthfully, since I've never had my engine apart that far I don't know how they (the gears) are made, assembled or attached. I know they are actually made of filled nylon, and they (usually) fail because engine heat softens the plastic and they lose teeth. But I agree that it seems possible and plausible to replace them with metal gears.
