APPENDIX H
TORQUE LIMITS
H-1.
SCOPE.
This appendix lists standard torque values (see Table H-1) and engine torque values (see Table H-2), and
provides general information for applying torque. Special torque values and tightening sequences are indicated in the
maintenance procedures for applicable components.
H-2.
GENERAL.
a.
Always use the torque values listed in Table H-1 or Table H-2 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
capscrews torque. Capscrew threaded into aluminum must also attain two capscrew diameters of thread
engagement.
