Torque Specifications
Tighten all bolts to torques specified in chart unless otherwise noted. Check tightness of bolts periodically, using bolt
chart as guide. Replace hardware with same grade bolt.
NOTE:Unlessotherwisespecied,high-strengthGrade5hexboltsareusedthroughoutassemblyofequipment.
Torque figures indicated are valid for non-greased or non-oiled threads and heads unless otherwise specified. There-
fore, do not grease or oil bolts or capscrews unless otherwise specified in this manual. When using locking elements,
increase torque values by 5%.
* GRADE or CLASS value for bolts and capscrews are identified by their head markings.
