Sprocket help!

[dnfrank]

Hello! I am new to this forum. I’m trying to figure out what kind of sprocket to purchase to replace the one pictured. I want an 11-tooth #41 sprocket but can’t find anything with the squares inside edges to fit the motor shaft. The inside flat edges measure 8mm. Any help is appreciated!

electric scooter parts .com..... (Santa Cruz, California.....great people--great website catalog....lotsa info to help).......they carry a variety of these sprockets for bldc motors from 9 tooth to 15 tooth. The problem is that this notched sprocket will only fit a T8F chains....the good news is that they also carry T8F axle sprockets up to 84 teeth....so match both sprockets for T8F chain and forget the 41.....then everything will match

Thanks so much! I actually found one on that website - 11 tooth for a #41 chain. Seems too good to be true but we’ll see when it arrives! A lot less work than taking the axle apart.
