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
