YM135 steering shaft

[Gjamtrac]

The bearing on the bottom of my vertical steering shaft went bad and I can't find a new one. Anyone know where I might find a used one? Why isn't there a place to add gear oil to this.

Thanks Winston, but the bearing I need is what Yanmar calls a "ball nut assembly" and is made onto the shaft.
I thought someone would know of a YM135 that is being scrapped or parted out, that I could get it off.
