FRONT PLANETARY WHEEL ENDS REPLACEMENT - CONTINUED
INSTALLATION - CONTINUED
Install wheel hub and disc assembly (16).
Install two bearing cups (20) with a suitable driving
sleeve into wheel hub.
Place wheel hub and disc assembly (16) on floor or
bench with the brake disc up.
Apply a thin film of clean lubricating oil to inner bear-
ing (19) and install in inner bearing cup (20).
Install new oil seal (17) with a suitable driver.
Use a sling and hoist or other suitable lifting device to
support weight of wheel hub and disc assembly (16).
Apply a thin film of clean oil to inside diameter of
new 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 disk assem-
bly onto spindle.
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 wheel hub.
To preload wheel bearings, seat bearings and related
components by tightening the hub bearing nut (14) to
100 lb-ft (136 Nm) while hub is rotated in both direc-
Back off hub bearing nut (14) to relieve preload on
bearings. Torque on nut should be 0 lb-ft (0 Nm).
Use planetary hub drag tool and a torque wrench to
check rolling torque while hub is rotating at a steady
rate (not starting torque). Record torque.
Tighten hub bearing nut (14) and check hub rolling torque again. Increase in rolling torque from zero preload should be
3 to 5 lb-ft (4.07 to 6.78 Nm) for new bearings.
