105 Upper Steering Bearing
 

So I needed to take the tower off my 105 to replace my hydro shift linkage and thought I might as well check out my steering while I had it apart. What I discovered is that there is currently no bearing at the top of the column. It looks like I can buy a new upper bearing. The question that I have based on reading some other threads is that there is maybe supposed to be an upper plastic retainer. I do not see this on the online parts breakdown. Rather just a bearing. Also my steering wheel does not appear to have any kind of offset to act as a retainer. I am wondering if I have the correct wheel. Also since the steering shaft does not have any sort of shoulder what stops it from dropping down? I have attached some pictures. Any help appreciated.

I just had one apart. There was a plastic bushing at the top op the column. It had a shoulder to keep it from going down inside the tube.

I use the same bearings that are in the front wheels. You can also get cheap ones at the hardware store that are a lot better then the plastic bushing.

So is there only a plastic bushing and no actual bearing?

This is the second time I have heard of using a wheel bearing. Would i also not need a bushing on the top of the bearing? I see that it shows a bearing on the parys breakdown but it does not show a close up of it.

Here is the steering colum from my IH Cub Cadet 70:

So is this the plastic bushing? Does the wheel go on next? Or is there a bearing that goes on top and then the wheel?

Hattrick, just put the bearing in the column in your first pic and then bolt the wheel on, nothing eles is needed.

So if I slide the bearing on the shaft and inside the column what stops the bearing from sliding down the shaft other than friction? It also seems like there would be a gap between the shaft and steering wheel.

This will help you visualize it better.
