9-6 . REAR PLANETARY WHEEL ENDS - REPLACE (Contd)
Apply a thin film of gear
lubricating oil to inside
diameter of oil seal (17) and to
oil seal journal surface of wheel
bearing spindle (10).
Align wheel hub and disc assembly
(16) with wheel bearing spindle
(10) . Push wheel hub and disc
assembly (16) onto spindle (10).
Install outer bearing cone (18)
in outer bearing cup (20).
Install hub bearing nut (14) and
draw wheel hub and disc assembly
(16) into position while rotating
PRELOAD WHEEL BEARINGS.
Seat bearings and related
components by tightening the
hub bearing nut (14) to 100 lb.
ft . while hub is rotated in both
Back off hub bearing nut (14) to
relieve preload on bearings.
Torque on nut should be 0 lb.
Use fabricated hub drag tool and a
torque wrench to check rolling torque
while hub is rotating at a steady
rate (not starting torque).
Tighten hub bearing nut (14) and
check hub rolling torque again.
Increase in rolling torque
from zero preload , should be 36
to 60 lb . in . for new bearings.
If bearings are to be reused , the
increase in rolling torque should be
1.5 to 2.5 lb . ft.
