Jack, reweighing is not the same thing as lubrication of the bearings. Mandatory reweigh intervals were measured in years
but the bearings required much more frequent maintenance. I don't know if this was an AAR thing, or whether the ICC or
other government agency required it. Guy Wilber would know! :-)

From what I recall in discussions here, this was an annual interval unless it was needed beforehand. The repack stencil for date and location would be reapplied after the work was completed.

Was there a regulated interval for repacking plain journals in the early 1950s?  If not, what was a typical interval, please?  I am hoping to be able to use repack dates to get realistic estimates of the dates of some tank car photos.
