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
