TM5-3825-229-14&P APPENDIX H TORQUE LIMITS H-1. GENERAL This section provides general torque limits for fasteners. Special torque values are indicated in the maintenance procedures for applicable components. The general torque values given in this appendix shall be used when specific torque values are not indicated in the maintenance procedures. H-2. TORQUE LIMITS Torque limits are listed in table H-1 for dry fasteners and in table H-2 for wet fasteners. Dry fasteners are defined as fasteners on which no lubricants are applied to the threads; wet fasteners are defined as fasteners on which special graphited or poly-disulphide greases or other extreme pressure lubricants are applied to the threads. Torque limits listed in Table H-3 are for specialized torques for dry fasteners. Table H-4 lists torques applicable to the semitrailer engine and are for wet fasteners.
