Tightening Torque Procedures
Listed below are some procedures which make fastener tightening more accurate and will
help to be sure that the proper torque is being applied.
1. Be sure that the torque wrench is properly calibrated and used by qualified
personnel to achieve the required fastener tightening torque for all critical parts.
The exception is the crosshead-balance lock nut which may be tightened using
the Ariel tried and true slugging method.
2. Always check to determine over what range the torque wrench is accurate, since
