I'm having trouble getting the gear out of the 4 speed tranmission. It appears to take some odd size wrench. The 1" is to large, the 15/16 too small. The grip area is so small I can't get a cresent wrench on it. Anyone with information or suggestions... I have been trying to get my speedo to work. I have tested everything and it appears that the speedo driven gear is not holding the cable.
