Assemble the constant drive Main Gear Subassembly according to Figure 1-6-2 first. Then build up the Wash Out Subassembly
according to 1-6-1. Insert the No.3 Main Shaft into the bearings and then add the No.4 Lock Ring and slide in the Main Gear
Subassembly. Add two M3x6 Button Head Screws to the Locking Ring, and the two screws are threaded into the holes on the
main rotor shaft.
The locking ring prevents the main shaft from sliding up. Line up the hole on the main gear and the main shaft, then insert M4x25
mm Bolt through them. Place a 4 mm M4 locknut on the other side of the autorotation hub, and then tighten the Bolt. Do not
over tighten the Bolt, otherwise the autorotation assembly will be distorted. Loosen the 3mm bolts holding the Upper and lower
bearing blocks for the 12mm main shaft. Wiggle the main shaft in the bearing blocks until the main shaft spins freely in the bearings.
This ensures the upper and lower bearing blocks are aligned. Push the lower bearing block up until the main shaft has no up
and down play. Then tighten the 3mm bolts for the upper and lower bearing blocks.
INSTALLATION OF THE LINKS

opening sizes on the two sides. Always snap the
bigger opening to the ball on swashplate gently and
afterward please check to make sure it is securely
attached and there is no damage or cracking.
