I am not to sure who did what to my steering shaft, so I am trying to find a replacement shaft. The shaft that was in the tractor had the end of the shaft machined down and a cone bearing pressed onto the end of the shaft. I am not happy with the way the bearing sits in the thurst bearing. My Super 55 is serial # 16 011, and uses part number 1ES-6767, Super 55s starting with serial number #30 109 use a 1ES-6767-A. Anybody know the difference between the two shafts? I am having my AGCO dealer looking into it too. Thanks for any information. <!-- s:shock: --><img src="{SMILIES_PATH}/icon_eek.gif" alt=":shock:" title="Shocked" /><!-- s:shock: --> 

Here are some pictures of the shaft end, the &quot;un-Oliver&quot; cone bearing that gets pressed on the end of the shaft, and the cup and thrust cone bearing.
