How to Use These Specs
-
Always use a calibrated torque wrench.
-
For angle torque bolts (e.g., head and rod bolts), tighten in two stages: torque to specified ft-lb first, then rotate the given degrees.
-
Replace torque-to-yield bolts after removal.
-
Apply proper lubrication on threads when specified to ensure accuracy.
