I have replaced the bearings on myTX472. Two bearing places in Spokane said
that there is no replacement available with the correct ID and OD.. They
could supply a bearing with the correct OD but the ID would be too large.
They did have a bronze sleeve bearing with exactly the correct OD and ID to
fill the space between the thru bolt and the available bearing. It was
relatively easy to change the bearings and stake the edge of the sheave.
