FIELD LEVEL MAINTENANCE
TORQUE LIMITS
SCOPE
This section provides general torque limits for the screws, hoses, and fittings used on the vehicle. Special torque
limits are listed in the maintenance procedures for applicable components. The general torque limits given in this
work package 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.
TORQUE LIMITS
Table 1 lists the torque limits for wet flange nuts. Table 2 lists the torque limits for wet socket head capscrews.
Table 3 lists torque limits for dry fasteners. Dry torque limits are used on screws that do not have high pressure
lubricants applied to the threads. Table 4 lists torque limits for wet fasteners. Wet torque limits are used on screws
that have high pressure lubricants applied to the threads. Table 5 lists the torque limits for SAE 37-degree flare
hose connections. Table 6 lists the torque limits for SAE 45-degree flare hose connections. Table 7 lists the torque
limits for ORS preformed packing face seal hose connections. Table 8 lists the torque limits for NPSM swivel
connections.
