I made the assumption (I know) that the PTO Shifter Lever is coupled to the Shift Lever Shaft by the Reamer Bolts, and that the Shaft is connected to the Shift Assy Arm via the Spring Pin, is that not correct? If it is not correct, how is the Shifter Lever coupled to the Shaft or is it. What does the Shifter Lever actuate if it is not coupled to the Shaft? What is the purpose of the Reamer Bolts? As I stated in a previous post, the Shift Lever Shaft will spin freely by hand, but the Shift Lever does not spin with it, which leads me to believe that the Lever is not coupled to the Shaft. If it is supposed to be coupled, is it possible that my Reamer Bolts sheared off at the OD of the Shaft. If I can spin the shaft, what would cause the Shift Lever to be frozen? The fact that I can spin the shaft also indicates to me that the Shift Assy Arm is most likely broken, is that a fair assessment, I don't want to assume again.
