4. PARTS LIST
4.2 Torque Charts
4.2 TORQUE GUIDELINES
DO NOT use these values if a different torque value or tightening procedure is given for a specific application.
Torque values listed are for general use only. Check tightness of fasteners periodically.
Shear bolts are designed to fail under predetermined loads. Always replace shear bolts with identical grade.
Fasteners should be replaced with the same or higher grade. If higher grade fasteners are used, these should only be
tightened to the strength of the original.
Make sure fasteners threads are clean and that you properly start thread engagement. This will prevent them from
failing when tightening.
