Torque Limits
E-1. SCOPE.
This section provides general torque limits for the screws, hoses, and fittings used on the IHMEE. 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.
Para E-4. shows torque data provided by ADI for fasteners used on the IHMEE. These torque values must be used whenever
applicable.
The material shown in Para E-5. is U.S. Army standard torque values. Ensure that you use the correct torque values for the
type and size fastener being tightened.
E-2. TORQUE LIMITS.
The tables on the following pages in this appendix may list values for "wet" or "dry" fasteners. Dry torque limits are used on
screws that do not have high-pressure lubricants applied to the threads. Wet torque limits are used on screws that have
high-pressure lubricants applied to the threads. Torque values are also provided for several styles of hose connections.
E-3. HOW TO USE THE TORQUE TABLES.
a. Screws and Nuts.
(1)
Measure the diameter of the screw you are installing (with a ruler).
(2)
Measure out 1 in. with the ruler and count the number of threads per inch.
