Torque values listed are for general use only. 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 fastener threads are clean and you properly start thread engagement. This will prevent them from failing when tightening. Tighten cap screws with plastic insert or crimped steel-type lock nuts to approximately 50 percent of amount shown in chart. Tighten toothed or serrated- type lock nuts to full torque value. Check tightness of cap screws periodically. INCH SERIES TORQUE CHART AllTractorManuals.com
