Assembly
NOTE: All mating surfaces of wheel and brake
components must be clean and dry during assem-
bly. No thread lubricant is permitted on these sur-
faces.
1. Position the spindle vertically.
2. Check bearing cones (7 & 28, Figure 3-6) for free
fit on the spindle (26).
3. Check threads in holes in end of spindle to be
certain capscrews will thread freely into spindle.
If not, re-tap threads.
4. Install bearing cups (6 & 29) in the wheel hub (1)as
follows:
a. Preshrink cups by packing them in dry ice, or
by placing them in a deep-freeze unit.
NOTE: Do not cool below -65°F (-54°C).
b. Install cups in wheel hub bores.
c. After cups have warmed to ambient tempera-
ture, press the cups tight against hub shoulder
as follows:
1.) Inner Cup (29) - Apply 23 tons (20,860 kg)
force.
2.) Outer Cup (6) - Apply 21 tons (19,050 kg)
force.
5. Install spacer (27). If necessary, tap lightly to seat
spacer against spindle. Spacer must fit tightly
against spindle shoulder.
6. Install pin (39) in groove in spindle and install inner
bearing cone (28) over pin and against the
spacer. (Cone is a loose fit on spindle.)
7. Install wheel hub (1) onto spindle (26). Install outer
pin (40) and outer bearing cone (7).
NOTE: To assure bearing lubrication during initial op-
eration lightly lubricate the bearings with hydraulic oil.
The brake assembly should not be installed at this
time in order to facilitate the bearing adjustment
procedure.
8. Install a new O-ring (9) onto spindle cap (10).
Lubricate the O-ring with clean hydraulic oil. In-
stall the cap into the end of spindle (26). The
tapped holes on the spindle cap must face the
outside for disassembly purposes.
Wheel Bearing Adjustment:
9. Install bearing retainer (13) onto the spindle with-
out any shims. The thickness of the retainer is
etched on the surface of the retainer. This side
should be facing outward. Use 4, equally spaced
capscrews in order to secure the retainer. Two
capscrews must be positioned adjacent to the
0.50 in. (12.7 mm) diameter access holes in the
retainer.
10. Seat the wheel bearings using the following pro-
cedure:
a. Tighten the 4 capscrews to 80 ft. lbs. (108 N.m)
torque. Rotate the wheel hub at least 3 full
revolutions.
b. Tighten the 4 capscrews to 160 ft. lbs. (217
N.m) torque. Rotate the wheel hub at least 3
full revolutions.
c. Repeat step 10-b until torque is maintained.
d. Loosen the 4 capscrews and rotate the hub at
least three revolutions.
e. Tighten the 4 capscrews to 60 ft. lbs. (81 N.m)
torque. Rotate the wheel hub at least 3 full
revolutions.
f. Tighten the 4 capscrews to 100 ft. lbs. (136
N.m) torque. Rotate the wheel hub at least 3
full revolutions.
g. Repeat 10 - f until torque is maintained.
11. Using a depth micrometer, measure and record
the distance between the face of bearing retainer
(13) and spindle (26) through each of the two 0.50
in (13 mm) diameter access holes.
12. Add the two dimensions measured in step 11 and
divide the sum by 2 to obtain the average depth.
13. Subtract the retainer plate thickness (etched on
the surface of the retainer plate (13) from the result
calculated in step 12.
14. Assemble a shim pack to equal the dimension
calculated in step 13 within 0.001 in (0.0254
mm).
