3.
Rest the spindle on the flange end. Lower the hub (9)
carefully onto the spindle shaft. Ensure that the bearing
cone (3) contacts the shoulder of the spindle. Squeeze
the small end of the bearing cone. Press the cone onto
the shaft.
4.
Measure the rolling torque of the assembly. This is the
initial value.
5.
Press the bearing cone (4) onto the spindle (8) with a
slight play of the bearing. The bearing end play should
measure .08 to .13 mm (0.003 to .005 inch).
6.
Press the inboard cone (4) until the rolling torque
increases 1.13 to 1.70 Nm (10 to 15 lb-in). This torque
should be higher than the torque measured in step (4).
If the increase of the torque is greater than 1.13 to 1.70
Nm (10 to 15 lb-in), then back off the cone by tapping
on the spindle end.
7.
Apply 4C-9507 Retaining Compound to the locknut (7).
Install the washer (5), the lock washer (6), and the
locknut (7).
8.
Tighten locknut (7) to 375 Nm (277 lb-ft). Rolling the
locknut will seat the bearings. The assembly should
have no end play. Check the rolling torque. The torque
must increase 1.13 to 4.52 Nm (10 to 40 lb-in) more
than the rolling torque measurement in step (4). This
will result in a bearing preload of .025 to .050 mm (0.001
to .002 inch).
9.
Tap the end of the spindle and check the rolling torque
again. If the rolling torque reading is different, tighten
the locknut (7) again.
10.
Bend the tanged washer (6) into the slot on the locknut.
Check the tab on the washer. The tab must align with
the locknut Tighten the tab with the locknut in order to
align.
11.
Install the pipe plug (12) and apply 9S-3263 Thread
Lock Compound.
12.
Install the spacer (13) and the O-ring.
