CHECKING BOLT TORQUE:
The tables shown below give correct torque values for various bolts and capscrews. Tighten all bolts to the torques specified
in chart unless otherwise noted. Replace hardware with the same strength bolt.
Torque figures indicated above are valid for non-greased or non-oiled threads and heads unless otherwise specified. Therefore, do not grease or
oil bolts or capscrews unless otherwise specified in this manual. When using locking elements, increase torque values by 5%.
* Torque value for bolts and capscrews are identified by their head markings.
