THIS WORK PACKAGE COVERS:
Scope, Torque Limits, How to use Torque Table, Tightening Metal Fasteners, Fastener Size and Thread Pattern,
Fastener Grade and Torque Limits for Engine.
This work package provides general torque limits for screws used on the M88A2 HRV vehicles. Special torque limits
are indicated 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 shall not be applied to screws that retain rubber components. The rubber components
may be damaged before the correct torque limit is reached. If a special torque limit is not given in the maintenance
instructions for rubber components, tighten the screw or nut until it touches the metal, then tighten it one more turn.
Table 1 lists dry torque limits. Dry torque limits are used on screws that do not have lubricants applied to the threads.
Table 2 lists wet torque limits. Wet torque limits are used on screws that have high--pressure lubricants applied to the
HOW TO USE TORQUE TABLE
a. Measure the diameter of the screw you are installing.
b. Count the number of threads per inch or use a pitch gage.
c. Under the heading SIZE, look down the left hand column until you find the diameter of the screw you are installing
(there will usually be two lines beginning with the same size).
d. In the second column under SIZE, find the number of threads per inch that matches the number of threads you
counted in step b.
