the bearing cups.
10. Apply thin coat of No. 2 general purpose lithium

lock nut while rotating shaft from 20 to 25 ft–lb (2.8 to 3.5
kg–m) to seat the bearings. Back off lock nut.
Note: Starting torque may exceed 10 ft–lb (1.4 kg–m)
when torquing the lock nut the second time. This torque
will fall once the nut starts to turn.
