APPENDIX J
TORQUE LIMITS

Section I. Introduction
J-1. SCOPE.
This section provides general torque limits for the screws, hoses, and fittings used on the truck. 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 instruc-
tions, tighten the screw or nut until it touches the metal bracket then tighten it one more turn.
J-2. TORQUE LIMITS.
Table J-1 lists the torque limits for wet flange nuts. Table J-2 lists the torque limits for wet socket head caps-
crews. Table J-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 J-4 lists torque limit for wet fasteners. Wet torque limits are
used on screws that have high pressure lubricants applied to the threads. Table J-5 lists the torque limits for
SAE 37 degree flare hose connections. Table J-6 lists the torque limits for SAE 45 degree flare hose connections.
Table J-7 lists the torque limits of ORS preformed packing face seal hose connections. Table J-8 lists the torque
limits for NPSM swivel connections.
J-3. HOW TO USE TORQUE TABLE.
