WARP TEN · 12-07-2018

An interesting situation and discussion. I tend to agree with Paul that it would seem there must be a source of steel or other strong abrasive to cause all that galling. The shaft is (I believe) case hardened steel and the bushing is bronze, a much softer metal so I would expect that it would not in itself cause the galling, rather the scoring would likely be more pronounced on the bushing itself. Curious to know if you examined the grease for what appear to be metal filings in it (although presumably some of it probably came from the shaft) and whether there was scoring inside the bronze bushing. --Bob
