I'm trying the penny in the primary trick and rear axle is locked in gear and held tight with the castleated nut but I still can't torque it down. Air wratchet doesn't do it. Pulling the Christmas tree shows the keyway depth around 3mm. Socalguy looked at an old one of his and got around 1.5-2mm.
Sorry for the shitty pic. iPhone won't focus on the key depth
So, what kind of Christmas tree do I have that it won't hold, and the keyway depth is larger than a stock 125?
