Make sure the outer end of the speedo gear has a good square hole in it, and the end of the speedo cable that mates with it also has a good square crimp that will enter the square hole in the gear properly. When you connect, make sure the end of the cable is fully seated in the gear, with the metal end of the sheath on the cable bottomed-out on the speedo gear adapter, before you tighten the threaded collar. If the cable isn't fully-engaged in the gear and you tighten the collar, the cable won't turn, and the plastic gear will be driven past its proper engagement with the drive gear on the output shaft and you'll have to go fishing for it.
