"There was zero reference in that post to make anyone think "wrong style
bearings…" so I think my reply there is fitting."
There are really only two reasons that could lead to bad clearances in a
tapered roller bearing -- wrong size bearing or damaged shaft. MarkWard
pointed you directly to the trouble, and certainly deserves credit for his
clear thinking. It is difficult to understand how any mechanic could
install a bearing half that was an eighth of an inch too large for the
shaft, but checking the clearances as MarkWard said would have instantly
found it .
