Nothing very specific on that floating around. Some metal gears have nylon teeth which make them cheaper and easier to produce. Years ago, I had a 1988 Olds Cutlas wagon with a plastic gear. It shredded as I started it up to leave work. Luckily the car wasn't in motion. I turned off the engine right away. And had no chain slap damage. Some are all nylon. I don't really care much about engine noise. So I told the mechanic to put an all metal gear for the chain.
I just had the timing belt and water pump changed on my 97 CRV, a few months ago.
I had a commercial "mixmaster", food mixer that goes over and into the bowl of food, very heavy and had space for 3 beaters, but the gears inside were made of fiber board or something. 3 teeth had come off. I tried to make new teeth with PC-70, I think it was, and it worked for a short while and then broke again.
