APPENDIX F

TORQUE LIMITS

This appendix lists standard torque values and provides general information and methods for

applying torque. Special torque values and sequences are indicated in the maintenance

procedures for applicable components.

To determine breakaway torque, thread nut onto screw or

bolt until at least two threads stick out. Nut shall not

make contact with a mating part. Stop the nut. Torque

necessary to begin turning nut again is the breakaway

torque. Do not reuse selflocking nuts that do not meet

minimum breakaway torque.
