NOTE: After 30 hours of operation, pump in extra grease to purge out any
moisture. Visually inspecting the purged grease at this time will give an
indication of conditions inside the bearing housing. A gradual increase in
moisture content indicates seal wear. If the grease begins to turn a dark, dirty
gray color, the driveshaft bearing and seals should be inspected and replaced
if necessary. Some discoloration of the grease is normal during the break‑in
period on a new set of seals.
