APPENDIX G
TORQUE LIMITS
G.1 SCOPE.
This appendix lists torque specifications and torquing instructions for specific
engine nuts and bolts.
G.2 TORQUE SPECIFICATION.
This application, preloading and torque angles in degrees
are listed in table G-1.
6.4 ENGINE TORQUING INSTRUCTIONS.
Preloading is applied with a torque wrench that is calibrated in foot pounds
(ft. lbs) or Newton meters (N · m).
Preloading is applied before angle torques.
All angle torques listed in table G-1 and table G-2 are accomplished by turning the
bolt or nut a specific number of degrees from a zero reference point as shown in
figure G-1.
Torquing of two or more bolts securing one assembly should be
accomplished in an alternating fashion to ensure assembly seating and equal load
d i s t r i b u t i o n .
For example, if angle torque specified is 30° initial then 30°
final, proceed as follows:
a.
Coat bolt and surface under bolt head with engine oil MIL-L2104C.
b.
Set bolts squarely to ensure assembly seating.
c .
Apply specified preload with torque wrench.
