TORQUE LIMITS

L-1. SCOPE.

This section provides general torque limits for the screws used on the flatrack. Special torque limits are listed in the

maintenance procedures for applicable components. The general torque limits given in this appendix shall be used

when specific torque limits are not indicated in the maintenance procedure. These general torque limits cannot be

applied to screws that retain rubber components. The rubber components will be damaged before the torque limit is

reached. If a special torque limit is not given in the maintenance instructions, tighten the screw or nut until it touches

the metal bracket then tighten it one more turn.

L-2. TORQUE LIMITS.

Table L-1 lists the torque limits for wet flange nuts. Table L-2 lists the torque limits for wet socket head capscrews.

Table L-3 lists dry torque limits for capscrews. Dry torque limits are used on screws that do not have high pressure

lubricants applied to the threads. Table L-4 lists wet torque limits for capscrews. Wet torque limits are used on screws

that have high pressure lubricants applied to the threads.
