Today I rebuilt the Honda's clutch assembly with new friction disks and springs. Then I disassembled the gears and spacers off the worn transmission countershaft and reassembled them onto a new one.
Half way through the clutch rebuild.
The countershaft gears reassembled onto the new shaft. Its hard to see in the picture but the splines on the old shaft are very worn out where the front sprocket for the chain rides. This allowed the sprocket to rock back and forth on the splines every time I shifted gears which was wearing a deep grove into them. I doubt it would have survived the trip.
