Installation Bolt Torque - Eaton L-852G Instruction Manual

either an alternating flashing bar of lights (i.e. YO---YF---YO---YF---YO---YF---... etc.), in
which the YOs flash on while the YFs flash off in an alternating fashion, or a solid bar of lights
that flash in unison (i.e. YO---YO---YO---YO---YO---YO---... etc.). In the case of an accidental
undesirable light bar installation (i.e. YO---YF---YF---YO---YO---YO---...etc.), each 852G-AP1
light unit's immediate powered flashing state is reprogrammable using Bluetooth technology. See
APPENDIX A for Bluetooth access instructions.

Installation Bolt Torque

•
Use fully threaded, 3/8-16 bolts meeting requirements of FAA EB83A. (P/N 21716 is
recommended.)
•
Use Heico-Lock or Nord-Lock stainless steel lock-washers per FAA specifications*.
•
Mounting base holes must be degreased, cleaned, and dried prior to bolt installation.
•
Base-to-fixture mating surfaces must be degreased, cleaned, and dried prior to
installation.
•
Apply marine grade anti-seize (K=.18) per manufacturer's instructions to each bolt.
•
Install the 3/8-16 bolts with lock-washers per lock-washer manufacturer's guidelines.
•
See Section 9.2 for Heico-Lock installation guidelines (2014)
•
Achieve a full final torque of 28 FT-LBS (37.9 N-m) ±10% with a calibrated torque
wrench.
•
Impact wrenches are not recommended as installation tools.
•
Check torque and re-torque all bolts within 2 weeks of initial installation.
•
Maintain all bolts by checking and re-torqueing per FAA specifications*.
•
If any lubricants or thread locking compounds are used (not recommended), torque must
be recalculated based on K factor provided by lubricant or compound manufacturer.
•
New bolts and lock-washers shall be used each time a light unit is removed from its base.
