CHART 2

RECOMMENDED NUT TORQUES

(Sheet 1 of 2)

TORQUES:

The importance of correct application can not be overemphasized.

Undertorque can result in unnecessary wear of nuts and bolts as well as the
parts they are holding together.  When insufficient pressures are applied, uneven
loads will be transmitted throughout the assembly which may result in excessive
wear or premature failure due to fatigue.  Overtorque can be equally damaging
because of failure of a bolt or nut from overstressing the threaded areas.  The fol-
lowing procedures should be followed to assure that the correct torque is applied:
1.

Self-Locking Fasteners - Add the friction torque from Chart 2A for sizes 8
through 7/16 to the recommended torque from Chart 2 to get the final
torque.  This would be the actual reading on the torque wrench.  To deter-
mine friction drag torque for sizes 1/2 through 1 1/4, turn the nut fully on to
the bolt and determine the torque required to turn the nut.  Add this friction
drag torque to the torque given in Chart 2.

2.

Castellated and Non-Self Locking Nuts - Use only the torque given in Chart
2.  Unless otherwise specified, when castellated nuts are used with a cotter
pin on moving joints, do not torque the nut.  Turn the nut onto the bolt until
proper grip is established and alignment with the cotter pin hole is achieved.
Then install the cotter pin.

GENERAL REQUIREMENTS.

1.

Calibrate the torque wrench periodically to assure accuracy.  Recheck fre-
quently.

2.

Ascertain that the bolt and nut threads are clean and dry (unless otherwise
specified by the manufacturers.)  If the bolt or nut is required to be lubricated
prior to tightening, the torque range should be reduced 50 percent.

3.

Use a bolt long enough to prevent bearing loads on the threads.  The com-
plete chamfer or end radius of the bolt or screw must extend through the
nut.

4.

Unique torques specified in the text of this manual supercede the torques
given in Charts 2 and 2A.

5.

Refer to the latest revision of Lycoming Service Table Limits, SSP1776, for
torques on parts used on Lycoming engines.

6.

A maximum of two AN960 washers may be added under bolt heads or nuts
to correct for variations in material thickness within the tolerances permitted.

7.

Self-Locking Fasteners - Limitations of the use of self-locking nuts, bolts and
screws including fasteners with non-metallic inserts are as follows:

a.

Fasteners incorporating self-locking devices shall not be reused if they
can be run-up using only fingers.  They may be reused if hand tools
are required to required to run them up providing there is no obvious
damage to the self-locking device prior to installation.

b.

Bolts 5/16 inch diameter and over with cotter pin holes may be used
with self-locking nuts.  Nuts with non-metallic locking devices may be
used in this application only if the bolts are free from burrs around the
cotter pin hole.

c.

Do not use self-locking nuts at joints which subject either the nut or bolt
to rotate.

d.

Never tap or rethread self-locking fasteners.  Do not use nuts, bolts or
screws with damaged threads or rough ends.
