I've disassembled and reassembled fans on Tays and BR710s for inspection and I can assure you that I've not slept well until after the airplane flies.Wow that bearing is glowing. That’s...impressive.
“Inspected bearing on ground. No noticeable elevated temperature. Reinstalled spinner. Verified free rotation. Cannot duplicate overheat on ground. Ops check sat - RTS.”

A Delta Airlines McDonnell Douglas MD-88, registration N906DL performing flight DL-1425 from Atlanta,GA to Baltimore,MD (USA) with 154 people on board, was enroute at FL330 about 30nm northwest of Raleigh/Durham,NC (USA) when the crew decided to divert to Raleigh/Durham due to a problem with one of the engines (JT8D). The aircraft landed safely on runway 23R about 30 minutes later.
The airline reported the crew received indication of a possible engine issue and diverted to Raleigh/Durham.
Looks like “bubble craps”
