Update.
I knocked the bearings out and took them to my local bearing supplier.
He took measurements and ordered bearings. I picked them up in Friday evening and am trying to install them now.
So. Here's some part numbers. And some measurements for anyone interested.
Inner bearings
Original.
Hyatt cup 11786Y 52Y OD 3.874
Hyatt bearing D11786 46-B ID 2.256
New
Timken cup 382 OD 3.874
Timken bearing 387 ID 2.246
Outer bearing
Original
Hyatt cup 11830Z 52-Y OD 3.542
Hyatt bearing B11630. 46B ID 2.032
New
Timken cup 28520 OD 3.543
Timken bearing 28580 ID 1.994
The bearing surfaces on the axle are
Inner 2.264
Outer 2.031
There's a pretty big problem. I'm looking for suggestions.
The bearings are supposed to be a slip fit on the axle and these won't even start.
Help.
