6.2.3 Torque Specifications
The following tables give correct torque values for various bolts, cap screws, and hydraulic fittings.
• Tighten all bolts to the torques specified in chart (unless otherwise noted throughout this manual).
• Replace hardware with the same strength and grade bolt.
• Check tightness of bolts periodically, using the tables below as a guide.
• Torque categories for bolts and cap screws are identified by their head markings.
SAE Bolt Torque Specifications
Torque values shown in this table are valid for non-greased, or non-oiled threads and heads. Therefore, do NOT
grease or oil bolts or cap screws unless otherwise specified in this manual.
