'\f CAUTION: .
When fasteners are removed, always reinstall them at the same location from which they were removed.
If a fastener needs to be replaced, use the correct part number fastener for that application. If the correct
part number fastener is not
available, a fastener of equal size and strength (or stronger) may be used.
Fasteners that are not reused, and those requiring thread
locking compound, will be called out. The correct
torque
values must be used when installing fasteners that require it. If the above conditions are not
followed, parts or system damage could result.
