I've also been through this a few times ...
The first time is chronicled HERE. Pictures included ...
It also happened twice last summer because I couldn't source the proper roll pin (the ones I was finding were too weak). I have since sourced some higher grade roll pins and I will be double-pinning the gear in an 'X' across the gear. There is no way to get a smaller roll pin inside the 3/16 roll pin that fits inside the gear. My gear was drilled for the second pin; however, I have to get the dist drive shaft drilled to match. I'll post pix once I undertake the work ...
