SCOPE .
Section II lists torque ratings for fasteners used on the generator set. When torque values are called out in
the maintenance procedures, whose supersede specified in this appendix. Table H-1 lists torque limits for
standard fasteners installed dry. Table H-2 provides formulas for converting the dry torque values to wet.
Table H-3 lists torque limits for metric fasteners installed dry.
