Section 5: Tail Rotor
The tail rotor’s function is to counter the torque of the power plant and keep the aircraft from rotating. It also provides the
ability to turn the aircraft while hovering by adjusting the pitch of the tail rotor blades through use of the directional controls.
Note: Refer to the Construction Manual for replacement details of these components.
Reference prints: E17-2000, E17-2001
SERVICE NOTES:
1. Remove bolt (part no. E00-2604) from the tail rotor barrel. Using a knife or a tool with a sharp edge, pry under the lip
of the bearing (part no. E17-1260) removing the bearing from the barrel. Replace with new bearings and insert the
bolt, tightening it just enough so that the head of the bolt can be rotated slightly with your fingers. Check end play by
using your hand and fingers, pushing the barrel from side to side to confirm proper end play.
2. Use the following procedure to remove tail rotor blades (part no. E17-6000) and pitch pins (part no. E17-6173):
A. First, mark each blade and pitch horn assembly as A and B. Indicate identity on the tail rotor barrel so reassembly
will be the same. This will maintain tail rotor balance.
B. Remove the two bolts that hold the blade to the pitch pin (part no. E00-2305 and E00-2308).
C. Carefully grasp the tail rotor blade and barrel with your hand and rotate while pulling outward.
D. Remove the snap rings and deburr the snap ring hole if needed. CAUTION: Be careful while doing this procedure
not to mark or scratch the inner surface of the tail rotor barrel.
E. Grasp the pitch pin and pull it out of the barrel. It may be necessary to insert a bolt in the tail rotor pin to lightly tap
on for removal. NOTE: A slide hammer may be fabricated to facilitate the removal of the pitch pin. See drawing on
the next page.
F. After removal of the pitch pin, remove the alignment bearing assembly (part no. E17-1270) and the thrust bearing
assembly (part no. E17-1280). Immerse the parts in a solvent to clean and remove the grease. After inspection of
parts, reassemble according to original procedures as outlined in the Construction Manual and on prints E17-
2000 and E17-2001.
NOTE: When changing out the tail rotor blades, refer to the tail rotor balancing procedures in the Construction Manual.
