Checking the all gnment of the wheel/rim installation is more important on cast spoke rims since the rims can be
drawn out of alignment when improperly tightened. Use the following installation procedures.
Slide inner rear of front tire and wheel in position over studs and push back far as possible. Use care to
avoid damage to threads on studs.
Install the outer wheel nut on front wheels and inner wheel nut on rear dual wheels. Run nuts on studs until
the nuts start to contact the wheel. Rotate wheel a half turn to allow parts to seat naturally.
Draw up stud nuts, alternately following the sequence (criss-cross pattern) illustrated in Figure 3-4. Do not
fully tighten the nuts at this time. This procedure will allow a uniform seating of nuts and insure the even face-to-
face contact of wheel and hub.
Continue tightening the nuts to the torque specifications in the Torque Chart using the same alternating
Install the outer rear wheel and repeat the preceding method. Be sure that both inner and outer tire valve
stems are accessible.
After operating the vehicle approximately 50 miles (80 km) check the stud nuts for tightness. Some natural
seating of parts may be encountered and the torque on nuts will drop. Retighten all nuts to specified torque.
To check and tighten the inner wheel to proper torque, first loosen the outer wheel nuts several turns. Then
tighten the inner nuts and retighten the outer nuts.
To prevent losing the seating of the outer wheel when checking the inner wheel torque, first loosen alternate outer
nuts. Then tighten the inner nuts and re- tighten the outer nuts. Then loosen the remaining outer nuts, tighten the
inner nuts and retighten the outer nuts.
Once each week inspect and retorque wheel stud nuts.
