CAUTION:
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

dirty gray, 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.
