W 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 torque. If the above conditions are not followed,
parts or system damage could result.
