I broke the key way shaft in my shift drum so I replaced it today. I have installed the clusters and drum with the forks in the right postion. The key way slot on the drum is in the 1 o'clock position. When I put the two cases back together with the shift shaft should I be able to go through all the gears or do I need to put something else back on. I don't want to seal the cases back up until I know that the trans is in right. Can anyone help please????
