NOTICE:
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 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 value
must be used when installing fasteners that require it. If the above conditions are not followed, parts or system
