APPENDIX D
TORQUE LIMITS
D-1.
SCOPE.
This appendix lists standard torque values, as shown in Table D-1, and provides general information for applying
torque. Special torque values and tightening sequences are indicated in the maintenance procedures for applicable
components.
D-2.
GENERAL.
a.
Always use the torque values listed in Table D-1 when the maintenance procedure does not give a specific
torque value.
b.
Unless otherwise indicated, standard torque tolerance shall be 10%.
c.
Torque values listed are based on clean, dry threads. Reduce torque by 10% when engine oil is used as a
lubricant. Reduce torque by 20% if new plated capscrews are used.
d.
Capscrews threaded into aluminum may require reductions In torque of 30% or more of Grade 5 capscrew
torque. Capscrew threaded into aluminum must also attain two capscrew diameters of thread engagement.
