This is my first post/question. I trust my questions more than my answers.
The inner, or second from the spindle nose, bearing of the pair of tapered roller bearings has overheated and the bore of the race is blue as well as the mating surface of the spindle. There is no measured difference (in tenths of thousandths) in spindle diameter in the blued area compared to adjacent areas that appear normal. However, the race is no longer a press fit on the spindle.
The bearing are Timkem, precision versions of there 387 bearing and 382 cup (387-90043 w/382)
What are possible ways of returning it to reasonable use without doing more damage? New precision bearings are not an immediate option due to cost.
Thanks,
Bob W.
