6. Thread the components together and tighten to the
following torque specications using only the correct
size wrenches. Use spanner wrenches on components
with spanner wrench holes or an open end wrench on
components with wrench ats. See Figure 6–5 for the
correct procedure. Refer to Table 6-III for torque unit
conversions. Be careful not to overtighten.
Table 6-III Horn/Booster Torque Unit Conversions
NOTE
Horn and booster torque specications
are higher than stud torque specs. Be
sure to tighten the horn or booster joints
to the higher torque limits.
Do not tighten the studs to these higher
ratings as it may induce unnecessary
stress in the assembly.
