APPENDIX F
TORQUE LIMITS
F-1.
GENERAL. Standard torque values are not
called out for individual maintenance procedures in this
manual. Use the standard torque of Tables F-1 and F-2.
F-2.
TORQUE DEFINITIONS.
a.
Breakaway Torque. Breakaway torque
(Table F-1) is defined as minimum torque required to
start the movement of a nut on or off a bolt with no axial
load on the nut and with the bolt completely through the
nut.
b.
Friction Torque. (Tare, Drag, Run on). The
torque required to overcome the internal friction between
a self-locking nut and bolt as the nut is being turned on
the bolt, but before the nut contacts the washer (no axial
load).
c.
Final torque is the sum of the friction torque
plus the applicable torque values from Table F-2 or
friction torque plus torque from the applicable
maintenance manual.
d.
Break-loose torque is defined as the effort to
break loose an axially loaded nut.
