Locate the MA128-47 tail rotor drive belt, and the MA128-46 tail rotor drive pulley. Refer to Illustrations 1i.1 and 1i.2 for this step.
Insert the tail rotor drive belt through the boom clamps as shown in the illustrations. Note the orientation of the tail rotor drive belt in
between the two tension pulleys. Place the tail rotor drive pulley on top of the lower bearing block, keeping correct orientation of the
drive belt between the tension pulleys.
Locate the MA128-52 main gear, MA128-49 autorotation hub, MA128-43 main shaft, MA0875-1 main shaft collar, MA0059-1
m2.5x6 socket bolt, four MA0062-2 m3x12 tapered socket bolts, and four MA0019 m3 locknuts. Refer to Illustration 1j for this
step. Start by assembling the autorotation hub to the main gear. The use of Tri-flow oil MA3200-02 is recommended to lubricate
the Torrington bearing in the MA128-49 autorotation hub. Tighten the MA0019 m3 locknuts equally around the hub. Do not use
thread locking compound on lock nuts. Loosely thread the MA0059-1 m2.5x6 socket bolt into the MA0875 main shaft collar.
Carefully slide the entire assembly into the frame above the tail rotor drive pulley. The MA128-43 main shaft is then inserted down
through the bearing blocks. (Note the orientation of the main shaft. The top of the main shaft has a hole all the way through, and the
bottom of the main shaft has a hole that only goes through half way.) Apply light pressure down on the main shaft, while tightening
the MA0059-1 m2.5x6 socket bolt. While tightening this bolt ensure that the collar is pushed up towards the upper main shaft,
eliminating main shaft vertical play.
