Press a 5x11x4mm bearing and bearing collar into the tail rotor gearbox as shown. Apply
Lite Lube
(or similar) grease to the gear on the shaft, and insert the shaft into the
gearbox.
MAKE SURE BOTH BEARINGS ARE COMPLETELY SEATED
.
Note:
Petroleum-based greases and oils (like automotive motor oil) can cause certain
plastics to crack or become brittle. Do not use petroleum-based oil or grease on the
tail rotor gears because the oil or grease will damage the plastic gearbox over time
and cause it to crack.

Secure the tail rotor bearing collar to the shaft with two 6-32 x 1/8" setscrews and
threadlock while lightly squeezing the hub and bearing collar together (this insures that
the tail rotor shaft and gear are correctly positioned inside the gearbox). Make sure no
threadlock gets on the tail rotor shaft inside the bearing collar.
