Bergen Intrepid Magnum Tazer, Manual, Page: 65 / 88

Remove the 2 ea 3X4 SHCS bolts from the sides of the tail gearbox, and
lubricate the o’rings of the bearing carrier.
Locate the end of the tail boom with the 2 drilled holes and insert the
TT drive system into the boom, pushing it ALL the way in and lining up the
holes in the tail boom with the threaded holes in the tail gearbox.
Reinstall the 2 ea 3X4 SHCS with loctite. These bolts do NOT require
excessive torque, just tighten them down. Now is a good time to slide
the horizontal fin clamp onto the boom, as it will be difficult to do
later….
