During inspection, four key areas should be checked for wear:

1. Check the babbitted surface of the pivoting journal shoe. Replace any shoe with scored or deeply scratched babbitted faces or signs of wear. Lightly scrape with a sharp scrapper if no wear is detected. Replace temperature detectors showing wear in the wire coverings.
2. Inspect the bore of the seal ri...
