Hey everyone,

I'm in the process of rebuilding the 4g transmission for my 4 stroke after the bolt that held the 10t rear sprocket fell off causing a domino effect of transmission failure. I got another sprocket but I don't know what size nut goes on the threaded shaft, anyone know?

Take her down to home depot size up the nuts with their threaded chart. I always buy the two closest sizes that appear to be correct.

Take a pencil and paper and lightly rub the pencil over the end of the shaft with the paper over it and do the same with the threads. Then you can go in home depot with a better idea on size and pitch.

Drill bits also help size threads using the back side will give you a general fitment
