RECOMMENDED TORQUES
A. GENERAL
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 throughout this
manual.
•
Check tightness of bolts periodically, using
bolt torque chart as a guide.
•
Replace hardware with the same strength
bolt.
•
Torque figures are valid for non-greased or
