Bolt Torque Chart - HLA BR72 Operator's Manual

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 for SAE hardware and Metric for metric hardware.
Make certain fastener threads are clean and you start thread engagement properly.
All torque values are given to specifications used on hardware defined by SAE J1701 MAR 99 & J1701M JUL 96.
