If thread locking adhesive is used, apply only one drop of Grade AV Loctite
®
to each of the six 3/8-inch (9.525-mm-) diameter mounting bolts. Torque the
bolts to 185
±
5 inch-pounds (20.902
±
0.565 Nt-m).
NOTE:
When Grade AV Loctite
®
is used, the bolts must be torqued to 185
±
5 inch-pounds.
9.
If using anti-seize lubricate, instead of threadlocking adhesive, on the threads
check with the manufacturer of the anti-seize lubricate to find out what the
Lubricity
"k"
factor
is for the compound that you are going to be using and
then refer to Table 3-1.
Table 3-1 Determining Torque Based on "K" Factor
If "k" factor is…
Then recommended torque is…
0.13 141/151
In-Lbs
0.14 152/162
In-Lbs
0.15 164/173

0.16 175/180

0.17 180/190

NOTE:
Always torque the bolts across the corners. Refer
to Retorquing
Mounting Bolts
in the
Maintenance
section. To torque the outer bolts across
corners, tighten bolts in noted sequence: #1 and #4, then #2 and #5, then #3 and
#6. See Fig 4-1
NOTE:
Applying more than one drop of Loctite to the bolt threads will create
future difficulty in removal of the bolts.
NOTE:
After several re-lampings, threaded holes may accumulate with dirt and
excessive Loctite. If this occurs, screws may not seat properly. Clean holes with
light weight oil or diesel fuel using a small fiber brush. Wipe the holes clean with
alcohol to remove all oil or diesel fuel and dirt. Clean with dry, oil-free, low-
pressure air. After the bolt has been retorqued three times, replace with new bolt.
If bolt is continuously loose, inspect taped thread in the light base flange for
damage. If thread is damaged, contact ADB Airfield Solutions, Inc., Sales
Department for field repair inserts kit.
