they use 2 on one of the gear shafts and 1 on the bottom of the crank on the inside slot. i guess it was just cold out or something, i got it to shift by pulling up swift and hard. put everything in including the crank, put the top case on, see if it will shift, it most likely will bind, just spin the big gear shaft and it will pop into gear. check for all gears, then pull the top case back off, yamabond it, and seal it up without touching anything else! nitrotate's advice and it worked great!
