2 BOLT AND SCREW TORQUE VALUES There are several areas on this machine where specific torque values are required. Nordco only uses Grade 5 or Grade 8 bolts. These are identified on the exploded view parts sheets. The following values are industry standards for torqueing bolts: SAE Grade and Head Markings Grade 5 Grade 8 Size N m lb-ft N m lb-ft 1/4 (.250) /16 (.3125) /8 (.375) /16 (.4375) /2 (.500) /16 (.5625) /8 (.625) /4" (.750) /8 (.875) Metric Grade and Head Markings Grade 8.8 Grade 10.9 Grade 12.9 Size N m lb-ft N m lb-ft N m lb-ft M M M M M M M Bolts, screws, and nuts 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. For example, if Grade 5 was called out but Grade 8 was used, you would torque to the requirements of Grade 5. Always turn off machine when performing maintenance, making adjustments, or whenever unintended movement of machine could occur; unless directed otherwise. Failure to comply could result in personal injury and/or damage to the machine. SYSTEM Mechanical, Page 2 JUNE/2004 ( )
