Locate the MA122-65 steel T/R hub, two MA0873-1 plastic T/R blade mounts, two MA120-39 ball bearings, two MA0457 thrust
bearings, two MA0446-4 steel shims, two MA0361 control balls, two MA0001 washers, two MA0049-3 m2x8 socket bolts, and two
MA0021 m4 lock nuts. Refer to Illustration 3-4g for this step. Use an MA0049-3 m2x8 socket bolt and an MA0001 washer to mount
the MA0361 control ball to each plastic blade mount. Note that on each blade mount there are two mounting points for the control
ball. For this model, the hole closest to the flat side of the T/R blade mount is correct. Push an MA120-39 ball bearing into each of the
inner pockets of the MA0873-1 plastic T/R blade mount. Before installing the thrust bearing, you will need to determine which of the
outer races has the larger inside diameter (I.D.) The outer race with the larger inside diameter will go in first. It is very important to
grease the ball race of the thrust bearing. We suggest using Tri-Flow synthetic grease (MA3200-06). Pack the open side of the ball race
with grease and install into the plastic T/R blade mount with the pocket facing in to keep the grease captured. Slide the outer race with
the smaller I.D. into the plastic T/R blade mount, followed by the MA0446-4 steel shim. Hold the MA122-65 steel tail hub vertical,
and gently slide on one completed T/R blade mount. We suggest using some "green" retaining compound such as MA3200-22 "super
lock-green" applied to threads of the MA0021 m4 lock nut. The best way to apply this compound is with a very small amount on the
tip of a toothpick. It is very important to not use too much retaining compound here, as getting any into the bearing or shims will result
in unsatisfactory performance. We have found that the best way to tighten the MA0021 m4 lock nut is with a Wiha #265 7.0mm nut
driver. Tighten the nut until a slight resistance is felt when rotating the grips, and then back the nut off until the grips rotate freely.

Locate two MA128-166 plastic T/R blades, four MA3700-155 1.5mm T/R blade mount spacers, two MA0097 Phillips bolts, two MA0019
m3 lock nuts, and two MA0056 m3x5 dog-point set screws. Refer to Illustration 3-4h for this step. Install the completed tail rotor hub
assembly onto the tail rotor output shaft. Note there are two "dimples" on the T/R shaft. The MA0056 m3x5 dog-point set screws must
engage the "dimple" on the T/R output shaft. Snap the pitch slider control links onto the MA0361 control balls on the plastic T/R blade
mount. Install the plastic T/R blades using the MA3700-155 T/R blade mount spacers, an MA0097 Phillips bolt and an MA0019 m3 lock
nut. These bolts should be tightened until the T/R blade can no longer "fall" under its own weight.
