APPENDIX H
TORQUE LIMITS
H-1. SCOPE.
This appendix lists standard torque values and provides general information for applying torque.
Special torque values and tightening sequences are indicated in the maintenance procedures for
applicable components.
H-2. GENERAL.
a. Always use the torque values listed in Table H-l when the maintenance procedure does not
give a specific torque value.
b. Unless otherwise indicated, standard torque tolerance shall be 10%.
c. Torque values listed are based on clean, dry threads. Reduce torque by 10% when engine
oil is used as a lubricant.
d. If replacement fasteners are of higher grade than originally supplied, use torque
specifications for the original. This will prevent equipment damage due to over torquing.
