Can someone please tell me the size of the socket that fits the lock nuts /jam nuts that hold the tranny shafts in the trap door. The SAE 1 inch is too small and 1 1/16 inch feels too big. Are these nuts metric? The bike is an 07 Road King with 6 speed transmission. Thank you.

 

My guess would be a 1-1/16" socket, since a 2002 Road King uses the same mainshaft and countershaft nut as a 2007 Road King. (35078-79)

Thanks Lookout, Just watched the video. Bert does say 1 1/16 inch. When I put this socket on the nut, it felt a little loose. I didn't want to try torquing to spec with the wrong size and round off the nut. This is my first venture into the transmission. It started with replacing a destroyed main drive bearing. One thing leads to another. I replaced the "walked" IPB race with a Baker high torque bearing. I'm trying to get a few more miles out of the OEM transmission. Eventually, will replace it with a Baker. I'm not a Harley mechanic, just enjoy working on my own bike and learning as I go.
