BOLT TORQUE CHART
Always tighten hardware to these values unless a different torque or tightening procedure is listed for a specif-
ic 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 sure fastener threads are clean and you start the thread engagement properly. All torque values are giv-
en to specification used on hardware defined by SAE J1701 & J1701M (Jul 96).
