General Torque Information
Mismatched or incorrect fasteners can result in damage or malfunction, or possible injury.
Take care to avoid mixing metric dimensioned fasteners and inch dimensioned fasteners.
Exceptions to these torques are given in the Maintenance Section, if necessary.
Prior to installation of any hardware, ensure that components are in near new condition. Bolts and threads
must not be worn or damaged. Threads must not have burrs or nicks. Hardware must be free of rust and
corrosion. Clean the hardware with a noncorrosive cleaner.
Do not lubricate the fastener threads except for the rust preventative. The rust preventative should be
applied by the supplier of that component for purposes of shipping and storage.
Other applications for lubricating components may also be specified in the
Maintenance
Section.
