Re: Steering Problem
Tom, I replied to your PM, but on reading your post above I think that you haven't gotten the mechanism completely broken apart. You should be able to get the horizontal shaft out of the pedestal and there should be a bearing on either side of the break.
From your descripton above it may be that the break is stuck in a "closed" position...
If I remember correctly, there are some set screws that hold bits and pieces in place that will prevent you from removing the horizontal shaft from the pedestal. I think they are located just aft of the sprocket...
