Here is my take on the fiber gear vs the aluminum one. The price difference is about $15 between the better fiber gear and the aluminum one. I have found that the aluminum ones are not noisy if mated with a new steel crank gear. ( the whine I believe is caused by differences in the pitch angle and roughness in gears.) Is the $30 cost of a new crank gear and the upgrade to the aluminum gear worth the risk of future failure? My customers and I say no. If you are throwing a motor together to go to the auction, I will send you a box of used timing gears that I usually throw away, cause they aren't worth the risk to me.
