Note: Torque specifications listed should not be confused with the torque value observed on
engines which have been run.
The Torque specifications take relaxation into account so sufficient clamping force exists
after an engine has reached operating temperature.
Torques listed are intended to cover highly critical areas. More extensive torques are found
