Robinson Racing Pinion Gear 48P 21T
This is a 48 pitch pinion gear made out of an alloy steel material. Available #160;in sizes from 12 to 35 teeth choose the number that will work best for you.
this gear didn't fix on my motor shaft.. I had to grind it down some with my dermal on the inside. I bought 2 others from robinson and they went on the motor fine.
Great quality last for ever befor needing to replace.
