Quick question. How much, if any, play should there be in a Max II jack shaft when the chains are off? On mine you can slide the sprocket assembly back and forth on the shaft. It’s almost like it needs more washers/ spacers between the sprocket assembly and the frame. Should the sprockets slide back and forth on the shaft? Will this movement stop and self align when the chains are tight???? One more question, I’m pretty sure I already know the answer. Is there any built-in misalignment with the jack shafts and the T-20? I’m new to the Max and just want to know for sure that I’m fixing this thing the correct way.
