Grease the bearings:
While slowly turning the bearing, use
1-2 shots of a lithium base NLGI #2
grease from a hand operated grease
gun to adequately fill the bearing
30-50% full.
Note:
Verify that the grease seals on both sides of the bearing are intact and not showing signs of
displacement or deformation once greasing activities have been completed. Over-greasing
bearings will cause premature failure of bearings if seals are compromised.
