ken studs, or damage to wheel components will result.

NOTE: After replacing broken stud(s), all wheel locknuts
must be re-torqued.

6. Check wheel assembly for gaps at each stud. Use a 0.0015
in. (0.038 mm) thickness gauge to detect gaps. If gaps are
detected, disassemble and reassemble wheel assembly and
recheck for gaps. If gaps are still detected, replace outer
rim half.
WARNING: Never inflate a wheel assembly without
having checked wheel locknut torques to ensure the
wheel locknuts are tightened to specifications. An as-
sembly with improperly tightened locknuts could sepa-
rate under pressure, resulting in serious injury or
death.
WARNING: Always use a tire inflation cage for infla-
tion purposes. Stand on one side of the cage during in-
flation, never directly in front. Keep hands out of cage
during inflation. Inflate assembly to recommended
pressure, using a clip-on air chuck. Do not exceed 50
psi (345 kPa) cold inflation pressure. Failure to follow
these instructions may result in serious injury or death.
7. Place wheel in safety cage and inflate tire to the
recommended tire pressure.
8. Check for leaks around rim edges and valve bore with
soapy water.
