A bearing using an oiling ring as a means of static oil feed must occasionally be serviced by removing the wear particles, grit, and moisture. How is this accomplished?

Correct Answer: Option A — Draining the bottom of the bearing lube oil sump.

Static oiling rings rely on a small sump within the bearing housing. Over time, contaminants like wear particles and moisture settle at the lowest point of this reservoir. Draining the bottom of the sump is the standard maintenance procedure to remove these impurities and prevent them from recirculating into the bearing.
