FIGURE 2-5. TIRE LIFTING SLING
(BODY REMOVED)
Due to its size and weight, always keep person-
nel away from a wheel assembly when it is being
removed and installed.
NOTE: Be sure to position outer dual wheel so that
tire valve bracket aligns with inner wheel inflation
line.
3. Install wedges onto studs and secure in place
with lubricated wheel nuts. Evenly tighten each
nut in an alternating (criss-cross) pattern as
shown in Figure 2-7) to 407 N·m (300 ft lbs)
torque.
4. Spin the wheel and check rim run-out. Maxi-
mum run-out is 5mm (0.20 in.). If run-out
exceeds specifications, then loosen all the nuts
and re-tighten them evenly as shown in Figure
2-7.
5. If run-out is OK, then tighten each nut as shown
in Figure 2-7 to 746 N·m (550 ft lbs) torque.

bracket on outer rim. Tighten cap screws to
standard torque.
7. Install wheel cover. Remove blocks from under
truck and lower truck to the ground.
8. Operate truck for one load and retighten wheel
nuts as specified in Step 6. Recheck nut torque
daily (each 24 hours of operation) to insure
proper torque is maintained on each nut. Once
torque is maintained, daily checking is no longer
required. Check intermittently to insure torque is
maintained.
