Well I cleaned the tractor parts up. Took the bearing over to buddy's place to get another. He cleaned it up and said it's going to be OK. The race is a tad bent, but will form back into place once everything is pressed in.
I know now what happened.
The last time the bearings blew apart I failed to clean the cap. There was bearing debris in the grease.
2 bearing parts jammed, wore the pin off, a bit of the threaded spindle, unscrewed the the nut.
Oh well it's cleaned out now. 🤣
Someone isn't the brightest light bulb at certain times.
Sunday I'll put all back together again and see if it's a working tractor again.
