Always tighten hardware to these values unless a different torque value or tightening procedure is listed
for a specific application.
Fasteners must always be replaced with the same grade as specified in the manual parts list.
Always use the proper tool for tightening hardware : SAE or SAE hardware and Metric for metric hardware.
Make sure fastener threads are clean and you start thread engagement properly.
